Box 5700 Eugene, OR 97405 (503) 683-6033 What is CopyQM? If you're eager to get going with CopyQM, skip to the section titled "Getting Started". Basically, CopyQM duplicates diskettes in a single pass. Introduced in 1987, CopyQM has been continually improved and up- dated. It now boasts the largest number of features of any PC- based diskette duplicating package. CopyQM reads a master diskette and formats, writes and verifies duplicates of the master diskette. Copying can be performed on up to six drives in a single session; copies are written on only one drive at a time. "No Hands" operation is featured--after you've started things, you needn't touch the keyboard again; just insert diskettes in drives as needed. In addition to the basic operating mode, the basic CopyQM package features the following: 1. Conversion between different formats. Unlike competing products which just copy the same format to different drives, CopyQM actually rebuilds the diskette format to match the drive. It's possible to convert from a 360K format to a 1.44M format. And the result is a "real" 1.44MB diskette with 1.44MB worth of diskette space. 2. Support of diskette image files. An image file created by CopyQM is a complete description of the information on a diskette. A comment may be included in the file with CopyQM's built-in editor. The image file is check- summed with a 32-bit CRC. _________________________________________________________________ Introduction 1 3. Copying of Apple Macintosh HD and DOS diskettes with no special processing. CopyQM will copy most PC-readable diskettes regardless of format with the "Blind" option. However, CopyQM will not copy low-density Apple Macin- tosh 800K diskettes. 4. Formatting of diskettes only when needed with "SMART" mode option. 5. Faster copying by copying only active data--the empty area on a partially-filled diskette is not copied. 6. Verifying of copies can be performed in several modes, ranging from none to a byte-by-byte comparison of copied data with the master diskette. 7. Selection of menu or command-line interface with com- plete on-line help. 8. Choice of direct hardware controller access or use of BIOS routines. CopyQM is also offered in a commercial "Plus" package with the following features: 1. Support of ASCII or binary serial numbering of copies. 2. Insertion of copy-protection information into copies. 3. Maintenance of a diskette usage log. 4. Diskette maintenance utility. 5. Creation of self-extracting diskette image files. 6. Execution of DOS commands or custom code overlays after each copy for support of labeling or auto-feeder devices. _________________________________________________________________ 2 Introduction CopyQM will not: * Write copies on more than one drive simultaneously. However, Sydex does offer SyDupe, which will write on up to three diskette drives at the same time. For more information on SyDupe, please contact Sydex. * Copy proprietary (e.g., Amiga, Apple ][, Atari 820) or copy-protected formats. * Copy individual files. The smallest unit of informa- tion that CopyQM can deal with is an entire diskette. * Copy one hard disk to another. CopyQM is a diskette- copying utility. * Copy individual files from a hard disk to a diskette. CopyQM is fast--in most cases it will copy at the best-case theoretical speed. The primary limitation in any diskette opera- tion is the time that it takes the diskette to complete one revolution. Our timings indicate that CopyQM can format, copy and verify a full 360K diskette in about 50 seconds. Larger capacity diskettes will, of course, require more time. Requirements At a minimum, the following four files are necessary for opera- tion of CopyQM: CINSTALL.EXE installs CopyQM. COPYQM.EXE implements the primary functions needed for dis- kette copying. CQMENU.EXE contains a menu interface and all on-line help. VIEWCONF.EXE is a utility to display the diskette configura- tion information being used by CopyQM. _________________________________________________________________ Introduction 3 Other text and program files may be present which describe the operation of CopyQM or support additional features, but the four files mentioned above are essential for successful operation. In almost all cases, CopyQM will be able to determine the con- figuration of a system without any sort of intervention. Unusual or special disk drive configurations, however, may require that the configuration be explicitly specified. For more information on how to construct a configuration file for all Sydex utilities, consult the section titled "Specifying a Diskette Configuration" near the end of this document. CopyQM requires the following operating environment for execu- tion: 1. An IBM PC-compatible with an 8088, 80286, 80386 or 80486 processor. Other system operating environments, such as PC emulation on non-PC systems (e.g., Commodore Amiga or Apple Macintosh) may work, but operation under them is not supported by Sydex. 2. PC-DOS or MS-DOS Version 3.3 or later. CopyQM has been successfully tested in a DOS session under IBM OS/2 Ver- sions 1.3 and 2.1, but OS/2 operation is not supported by Sydex. Other DOS-compatible systems such as Novell's DR-DOS or The Software Link's PC-MOS may result in successful operation, but these have not been fully tested by Sydex. 3. At least 256K of available base memory, sometimes referred to as "RAM". 4. A hard disk with at least 2MB of free space for tem- porary files created by CopyQM. 5. At least one diskette drive local to the system running CopyQM. Network diskette drives are not supported. CopyQM does not require, but can make use of the following: 1. Extended memory that is managed by an XMS-compatible memory manager such as Microsoft's HIMEM.SYS or Quarterdeck's QEMM. _________________________________________________________________ 4 Requirements 2. Expanded memory, or LIM (Lotus-Intel-Microsoft), that is managed by a a driver that is compliant with EMS 4.0 or later. 3. Additional diskette adapters. Sydex has tested the Micro Solutions Compaticard I, II and IV adapters. Cer- tain non-standard diskette adapters, such as the IBM PS/2 5.25" Diskette Adapter/A or the Micro Solutions Backpack tm drive may require that the BIOS interface option of CopyQM be selected. CopyQM will operate under Microsoft's Windowstm or Quarterdeck's Desqviewtm. However, because diskette copying is a time-critical application, performance under any multi-tasking environment will be degraded somewhat. The actual amount of the degradation depends on several factors, including the scheduling algorithms used by the multitasking software. Use of the BIOS interface op- tion is recommended. Executing more than one copy of CopyQM under control of a multi- tasking executive, such as Windows is not recommended. Severe performance degradation will result. If two sets of diskette copies are required, running two CopyQM sessions consecutively will result in significantly better performance than attempting to execute the sessions concurrently. For efficient concurrent operation on several diskette drives, contact Sydex about the SyDupe duplicating package. CopyQM will support a total configuration of up to twelve dis- kette drives. A CopyQM session can make use of up to seven dis- kette drives--one for reading and six for writing. Getting Started To install CopyQM, execute the CINSTALL program. CINSTALL will copy all necessary files and perform several system checks re- lated to CopyQM execution. For example, if CopyQM is to be in- stalled from drive A:, enter the following command at the DOS prompt: A:CINSTALL _________________________________________________________________ Requirements 5 If you're using a portable computer with an LCD display, you may want to select a monochrome color set to improve display readability: A:CINSTALL /MONO In most cases, this is all that will be required to get CopyQM up and running. First-time users should execute CopyQM through the menu interface furnished by CQMenu. Entering the following command at a DOS com- mand prompt will initiate execution of CQMenu: CQMENU CQMenu displays a menu and translates the menu choices into a com- mand line for CopyQM. After all selections have been made, COPYQM.EXE is located and read into memory overlaying CQMenu. CQMenu also contains a full on-line help facility for CopyQM. Help related to the current selected menu item can be obtained by pressing F1. In addition, a general help facility which describes command-line syntax and configuration file setup can be displayed by pressing F1 a second time. All of the features of CopyQM are not available through CQMenu's interface. Some of the more obscure facilities are accessible only through the DOS command line interface to CopyQM. On-line help is available for the command-line syntax of CopyQM by entering the following command: COPYQM /HELP _________________________________________________________________ 6 Getting Started CopyQM Operation Once menu selections have been made from CQMenu or the command line for CopyQM has been entered, CopyQM begins execution. Opera- tion of CopyQM is divided into two phases, reading the master dis- kette or image file, and writing the copies or diskette image file. Because CopyQM continuously accesses diskette drives to obtain their operating status, diskette changes are permitted when drive lights are illuminated. In addition, since CopyQM is sensitive to drive changes, it may be necessary to remove a diskette and then re-insert it into the same drive to indicate to CopyQM that a change has occurred. When a diskette or image file is being read, a box corresponding to the drive currently being accessed is shown containing a mes- sage indicating the status of the current operation. If the ES- Cape key is pressed before CopyQM is able to read the master dis- kette, execution terminates and CopyQM exits to DOS. A summary of information relating to the diskette is also shown. Sector size indicates the size in bytes of each sector. Sectors/track specifies the number of sectors that occur on each track. Sides reports either 1 for single-sided formats, or 2 for double-sided. Density can show values of low for double-density (360K and 720K), high for high density (1.2M and 1.44M), or ex- tended for 2.88M media. Data cylinders indicates the number of cylinders containing active data. The amount of memory used to hold the data from the diskette is also shown. The DOS volume label name, or the first 11 characters of an Apple Macintosh volume label is shown. If no volume label can be found, "** NONE **" is displayed. If creation of a diskette image file has been requested, the file is written after the diskette has been completed. If the conver- sion option has been specified, a temporary diskette image file will be written and the requested conversion will be performed as the image file is read back into memory. If copying to diskettes has been requested, the following prompt will be displayed: _________________________________________________________________ CopyQM Operation 7 Enter copy count (ESCape to exit) - Between 1 and 9,999 copies may be requested; after the desired number is entered, the Enter key is pressed. If the ESCape key is pressed instead, CopyQM will exit to DOS. After the master diskette or image file has been read and processed, CopyQM begins the writing phase. Up to six drives can be shown on the writing status display. Note that only those drives which support the diskette format cur- rently being copied are shown. For example, if a high-density 5.25" (1.2M) master diskette were being copied, only drives capable of high-density support would be displayed. The "thermometer" bar displayed when writing diskettes shows the progress of the copy operation. A solid, red bar indicates that active data is being transferred; a hatched, green bar indicates that an inactive area is being formatted. When all requested copies have been completed, the following mes- sage appears: All copies done. Press any key to continue... If the ESCape key is pressed before all copies have been written, the following message appears: ESCape pressed. Press any key to continue... If the ESCape key is pressed again, CopyQM exits to DOS. Any other key causes CopyQM to request the next master diskette for reading. CopyQM Command Line Syntax In order to get an idea of how to use CopyQM, consider the follow- ing hypothetical PC setup: _________________________________________________________________ 8 CopyQM Operation Drive A: is a 1.44M 3.5" diskette drive Drive B: is a 1.2M 5.25" diskette drive Drive C: is a hard disk Drive D: is a 1.44M 3.5" diskette drive Drive E: is a 1.2M 5.25" diskette drive The following commands illustrate how to construct commands to perform most common copying tasks: 1. Copy a 3.5" diskette using one drive: COPYQM A: 2. Copy a 5.25" diskette using one drive: COPYQM B: 3. Copy a 5.25" diskette using two drives for writing: COPYQM B: E: 4. Copy a 5.25" 360K diskette to 3.5" 720K diskette: COPYQM A: SOURCE=B: CONVERT=720K 5. Copy a 3.5" diskette using pre-formatted diskettes: COPYQM A: SMART 6. Make an image file (MYIMAGE) of a 3.5" diskette: COPYQM A: RECORD=C:MYIMAGE 7. Make a 3.5" diskette from an image file (MYIMAGE): COPYQM A: PLAYBACK=C:MYIMAGE 8. Make one copy each of a set of 3.5" diskettes: COPYQM A: COUNT=1 REPEAT _________________________________________________________________ Command Line Syntax 9 In general, the format of a CopyQM command is: COPYQM <drives> <options> Where <drives> are drive letters (each followed by a colon) and <options> are either single words or a word followed by an equals sign (=) and a value. Many options are available with CopyQM. What follows is a descrip- tion of all options, grouped by function. For more examples of command lines, consult the section titled COMMAND LINE EXAMPLES. Some options require a value; others do not. A value may be as- signed to an option by following the option with an equals sign (=) and the value. For example, the COUNT option, which controls the number of copies to be made, requires a value. COUNT=10 specifies that 10 copies will be made. Most options also have an abbreviation which can be used instead of the full spelling. Thus, WRITEPROTECT, which causes CopyQM to make sure that the master diskette is write-protected, can be ab- breviated as WR. Basic Operating Options These options change, in a basic way, the manner in which CopyQM operates. BIOS specifies that the system BIOS should be used for dis- kette access. Normally, the controller hardware is directly accessed by CopyQM, but operation under some multi-tasking environments, such as Microsoft Windows may require that this option be specified. The word BIOS can be abbreviated as BI. BLIND specifies that CopyQM should not consider the content of the diskette to be copied, but only its format. This option is useful when the diskette to be copied was not created on a DOS or Apple Macintosh system, or has a non-standard boot sector. Caution: If a DOS dis- kette produces the Not a DOS Diskette error message, this may indicate that the diskette contains a boot sec- _________________________________________________________________ 10 Command Line Syntax tor virus. Before switching to BLIND copying, use any of the commercially available virus scanning packages to determine that the diskette does not contain a virus. BLIND may be abbreviated as BL. To control the way in which BLIND mode processes a diskette, see the section titled SPECIFYING DISKETTE PARAMETERS IN BLIND MODE. CHECK disables the writing of copies and enables a byte-by- byte comparison of copies with a master diskette. Use CHECK to verify that a diskette is a true unmodified copy of the original master. CHECK may be abbreviated as CH. HELP or /HELP gets this on-line help display. H and /H will also activate the CopyQM help display. Specifying A Different Drive for Reading CopyQM normally uses the first drive specified to read the master diskette. However, there are some situations where the drive used for reading should not be used for writing the copies. SOURCE specifies the drive to be used to read the master dis- kette. For example SOURCE=A: indicates that drive A: should be used to read the master diskette. Unless the same drive occurs in the drive list portion of the CopyQM command line, it will not be used for writing. SOURCE may be abbreviated to SO. Display and Sounds These options control the appearance of the display or the use of the PC's speaker: MONO forces CopyQM to use a monochrome color set for all dis- plays. Normally, CopyQM will detect the presence of monochrome-only displays and change its operation ac- cordingly. However, some lap-top systems with LCD or plasma displays may give a more readable display if this option is used. MONO may be abbreviated as MO. _________________________________________________________________ Command Line Syntax 11 NAG activates a "wake-up!" audio signal. If approximately 20 seconds of inactivity occur, a short tone will be sounded every 20 seconds until some action has been taken. SILENT specifies that no audible signaling should be used at all. This is useful in environments where noise must be kept to a minimum, such as in a crowded office. SILENT may be abbreviated as SIL. NOPAUSE disables a "Press any key to continue" message after the master diskette has been read and between each set of copies. The pause is normally inserted to give the user an opportunity to read any important status mes- sages before the screen is erased. NOPAUSE may be ab- breviated to NOP. Converting Between Formats The CONVERT option may be used to change the format of a master diskette and may be used with all copying modes; NORMAL, RECORD and PLAYBACK. CONVERT specifies that the data on the master diskette is to be converted to a different format. A target format must be specified with this option and can be 360K, 720K, 1.2M, 1.44M or 2.88M. The diskette drive used for writing must be capable of supporting the target format. Thus, specifying CONVERT=360K when using a 3.5" DSDD master diskette will cause the data from this diskette to be re-formatted for writing to a 5.25" DSDD (360K) diskette. The exact nature of the re-formatting operation depends on whether or not the BLIND option has been specified. If a normal DOS-mode copy is being done, the boot sec- tor and file allocation tables from the master diskette are modified to conform to the new format and the result will be a readable DOS diskette. It is impor- tant that the amount of data on the master diskette fit the new format. In other words, don't try to pour a quart of data into a pint-sized diskette. _________________________________________________________________ 12 Command Line Syntax If, on the other hand, the BLIND copy option has been specified, no alteration of the data read from the master diskette is performed. Data is simply "re- packed" into the appropriate-sized tracks on the target diskette. In this context, Apple Macintosh HD dis- kettes are considered to be "blind" copies. Each target format has the following characteristics: 360K 40 tracks, 5.25" DSDD, 9 512-byte sectors 720K 80 tracks, 3.5" DSDD, 9 512-byte sectors 1.2M 80 tracks, 5.25" DSHD, 15 512-byte sectors 1.44M 80 tracks, 3.5" DSHD, 18 512-byte sectors 2.88M 80 tracks, 3.5" DSED, 36 512-byte sectors CONVERT may be abbreviated as CON. Memory Usage Several options control how memory is used by CopyQM. Normally, CopyQM stores data from the master diskette first in main memory, then, after main memory has been used up, XMS (extended memory) is used if it is present. If no XMS is present, or if it cannot contain the remainder of the diskette data, EMS (expanded memory) is used. Finally, a hard disk file is created to hold any ex- cess. The location of this hard disk file can be controlled by setting either the TEMP or CQTEMP environment variables to the drive and path name of a hard disk subdirectory. For example, to specify that CopyQM should create its temporary files in the directory called MYDIR on the C: drive, the following DOS state- ment could be placed in the AUTOEXEC.BAT file: SET CQTEMP=C:\MYDIR The setting of the CQTEMP environment variable takes precedence over the setting of TEMP. The NOEMS option specifies that EMS (expanded memory) must not be used by CopyQM. This option can be used when EMS is to be reserved for use by other programs. NOXMS specifies that XMS (extended memory) must not be used by CopyQM. _________________________________________________________________ Command Line Syntax 13 If both NOEMS and NOXMS are specified, all data that will not fit into main memory is written to hard disk. If hard disk storage is not available, an Insufficient Memory error is displayed. Formatting and Verifying Several options are available to control the manner in which CopyQM formats and verifies diskettes. SMART indicates that CopyQM should assume that the current diskette is formatted and bypass the formatting opera- tion. Should an error occur while writing or format- ting, CopyQM will format the remainder of the diskette before writing to it. SMART may be abbreviated as SM. If no errors in the existing format have been detected at the point where the last cylinder of active data has been written, CopyQM will end processing of the dis- kette without checking the remainder of the diskette to see if it is formatted. However, if CopyQM has begun formatting after detecting an error in the existing for- mat, the area between the last cylinder of active data and the end of the diskette will be formatted unless the QUICK option (see following) has also been specified. QUICK specifies that CopyQM should write copies only as far as the last cylinder containing active data. If QUICK is specified, no formatting is performed between the last cylinder of data and the end of the diskette, even if the diskette is not formatted. This will normally not affect reading from the diskette, but will inhibit writing any large amount of data to the diskette if it has not been pre-formatted. QUICK may be abbreviated to QU. COMPARE changes the way in which data just written is verified. Normally, CopyQM simply reads the written data back without inspecting its actual content. If a computer system's hardware is operating correctly, the probability of an undetected error is vanishingly small and should suffice for all but the most demanding ap- plications. If COMPARE is specified, data is read back _________________________________________________________________ 14 Command Line Syntax from the copy and compared with the data from the master diskette. The performance of CopyQM will be degraded somewhat if this option is specified because of added CPU overhead. COMPARE can be abbreviated as COM. VERIFY specifies the extent and type of verification of writ- ten data that should be performed. Normally, CopyQM verifies data that lies between the start of the dis- kette and the last cylinder of data, but not between the last cylinder of data and the end of the diskette. Specifying VERIFY=ALL, will cause the entire diskette to be verified by CopyQM. Specifying VERIFY=NONE will bypass the verification process for the entire diskette. VERIFY=DATA is the default which specifies that only active data will be verified. VERIFY may be abbreviated as VE; ALL, NONE and DATA may be abbreviated as A, N and D, respectively. Diskette Image Files One of the unique features of CopyQM is its ability to create a DOS file which represents the exact image of a diskette. To make a DOS file from a diskette, one records the diskette. Re- creating the diskette from an image file is called playback. Any diskette that can be read by CopyQM can be recorded. In addition, the ability to add a comment to the image file is offered. An image file's integrity is assured by a cyclical redundancy checksum (CRC) of the contents of the entire diskette image. Diskette image files may be treated just as if they were master diskettes. They may be converted to other formats (see the CONVERT option), and may be serial-numbered (CopyQM Plus only). _________________________________________________________________ Command Line Syntax 15 The RECORD option specifies that a diskette image file is to be created. A file name must be given with this op- tion; for example, RECORD=MYFILE would cause a diskette image to be written to the file called MYFILE. A spe- cial case occurs when the file name contains one or more question marks (?). CopyQM starts by substituting the number zero (0) for each question mark. Before each diskette image file is recorded, the rightmost question mark position is increased by one and the resulting file name used to record the next diskette image. In other words, a file name of A?B?C?D? would result in image files named A0B0C0D1, A0B0C0D2...A9B9C9D9. Thus many diskette image files can be created in a single session. If the file name given for RECORD is /ASK, a prompt for a file name will be displayed after each master has been read. RECORD may be abbreviated to REC. PLAYBACK does exactly the opposite of what RECORD does-- CopyQM creates diskettes from the diskette image file. At least one file name is required, but more than one may be specified if the file names are separated by com- mas (,). Thus, PLAYBACK=AFILE,BFILE,CFILE would result in diskettes being created from the files AFILE, BFILE and CFILE. File name "wild card" characters of "*" and "?" are permitted to specify more than one file. CopyQM builds a list of all matching file names and sorts the list by file name and extent. Thus, a specification of PLAYBACK=B,A,D,C would result in read- ing the specified files in the order A, B, C and D. If the file name given for PLAYBACK is /ASK, a prompt will appear onscreen for a file name whenever a master dis- kette is required. PLAYBACK may be abbreviated to PL. NOCOMMENT suppresses both the prompt for and the display of the comment record associated with an image file. In other words, if NOCOMMENT is used, a comment will not be requested when an image file is created, nor will one be displayed when an image file is "played back"; even if the image file has a comment associated with it. NOCOMMENT can be abbreviated to NOC. _________________________________________________________________ 16 Command Line Syntax Comment entry is not enabled with unregistered copies of CopyQM. However, a comment may be added to an image file with the ICOMMENT utility which accompanies regis- tered copies of CopyQM. NOSQUEEZE disables the run-length encoding used on image files. If a very slow (PC XT-class) system is being used, this option may significantly improve the speed at which a diskette image file is created. However, any disk space benefits gained by compression will be lost. NOSQUEEZE can be abbreviated to NOS. Blind Mode If the BLIND copying option is specified, (see "Basic Operating Options" above), CopyQM will attempt to determine the format of the master diskette automatically. However, if the format of the master diskette is sufficiently different from "normal" dis- kettes, it may not be possible to correctly determine the format. There are several parameters which can be used to explicitly describe various aspects of a diskette format. TRACKS specifies the number of tracks or cylinders to be copied. Normally, CopyQM assumes either 40 or 80 tracks, depending on the diskette density and drive type. However, there are some diskette formats which use a different number of tracks. For example, TRACKS=41 specifies that 41 tracks are to be copied. TRACKS may be abbreviated to TR. SIDES explicitly specifies the number of diskette sides to be copied. Often, a single-sided format will contain unrelated data from another system on its second side. SIDES=1 will override CopyQM's determination that a dis- kette is double-sided. SIDES may be abbreviated to SID. FIRST specifies the number of the first sector on a track. Normally, this sector is assumed to be 1, but some dis- kette formats use non-standard values, such as 0, for the first sector. FIRST=128 would specify that the first sector on a track is number 128. FIRST may be abbreviated to FI. _________________________________________________________________ Command Line Syntax 17 "Shelling Out" Between Copies For special processing of copies, such as creation of labels, or maintenance of a copy log, CopyQM Plus offers facilities to ex- ecute DOS commands after each copy is written. CopyQM Plus also has a facility for serial numbering; contact Sydex for details about upgrading a standard license to CopyQM Plus. CopyQM Plus offers a method to insert copy-protection informa- tion. Contact Sydex for details. Miscellaneous Options Several options do not fit neatly into any of the above categories and are described here: CMD specifies that a CopyQM command is continued in a named ASCII file. Within such a file, line boundaries are ignored and a statement may be up to 512 characters long. For example, COPYQM A: CMD=MOREPARS indicates that extra command information is contained in the file MOREPARS. A command file may itself in- clude a CMD option; however, a "circular" command file structure is not detected by CopyQM and will result in a never-ending loop. RETRIES specifies that CopyQM writes be retried a specified maximum number of times. For example RETRIES=13 specifies that write operations that fail may be retried up to 13 times. Normally, write failures are retried a maximum of three times. RETRIES may be ab- breviated to RET. _________________________________________________________________ 18 Command Line Syntax VSN requires no value and specifies that random volume serial numbers should be placed in the boot sector of every DOS diskette copy made by CopyQM. For this op- tion to take effect, the boot sector of the master dis- kette must have been generated by a DOS system later than 4.0. WRITEPROTECT ensures that every master diskette is write- protected. If a master is read by CopyQM that is not protected (either by adhesive tab for 5.25" diskettes or protect "slider" on 3.5" diskettes), an error mes- sage is generated and the master diskette is rejected. WRITEPROTECT may be abbreviated to WR. STATUS is used where diskette drives without hardware change status lines are used. Drives without this feature are primarily 5.25" 360K drives, though some 3.5" 720K drives also lack the change-detection capability. If a copy involving drives without change status lines is attempted and the BIOS option is specified, a test for diskette change is not made until the completion of a copy. STATUS can be used to override this mode of operation and specifies that drives must be checked for status changes after a specified number of cylinders have been written. Thus, STATUS=8 specifies that status checking is performed after every 8 cylinders have been written. The COPYQM Environment Variable Any of the above options may be assigned to the environment vari- able "COPYQM" for use by all CopyQM sessions. However, since the equal sign "=" is illegal inside of an environment string, terms requiring values must use the semicolon ";" instead of the equal sign. Thus, to specify by default that all CopyQM sessions are to verify all data and sound a 20-second inactivity signal, the following DOS command is used: SET COPYQM=NAG VERIFY;ALL _________________________________________________________________ Command Line Syntax 19 Locating Temporary Files In addition to the COPYQM environment variable, the variable CQTEMP can be used to explicitly specify a drive and path to be used to hold copy data that exceeds the limit of memory. If CopyQM cannot find the CQTEMP environment variable, it searches for one named TEMP. If neither variable is defined, the root directory on the first hard disk is used. The following DOS com- mand specifies that all hard disk overflow data be kept in the TEMPFILE subdirectory on drive G: SET CQTEMP=G:\TEMPFILE Command Examples Here are some more examples of CopyQM command lines: COPYQM A: B: Reads the master diskette in A:, writes copies in A: and B:. COPYQM SOURCE=B: A: Reads the master in B:, writes copies in A:. COPYQM SOURCE=A: B: COUNT=1 REPEAT CONV=720K Reads a set of master diskettes in A:, converts it to 720K format, writes one copy of each master in B:. COPYQM SOURCE=A: RECORD=MYFILE Reads a master diskette in A:, produces a diskette image file called MYFILE. COPYQM A: CHECK Reads a master diskette in A:, reads and compares diskettes read in A:. No diskette writing is done. _________________________________________________________________ 20 Command Line Syntax COPYQM A: SMART COMPARE NOEMS Reads a master diskette A:, writes copies in A:, skips for- matting of the copies if possible, performs verification of the copies by reading back copies and comparing the data with the master. Expanded Memory, if available, will not be used. COPYQM A: PLAY=DISK* COUNT=3 REPEAT Reads diskette image files whose names satisfy the file specification of DISK* and makes three copies of each file. Differences from Earlier Versions Users of previous versions of CopyQM will notice many differences in Version 3.1. A few of the more significant ones are as fol- lows: 1. Improved display. More information has been incor- porated into an easier-to-read display. 2. Image file embedded comments. A comment can now be en- tered at image file creation time or added later to an image file with the ICOMMENT utility. Image file com- ments are displayed when the image file is read by CopyQM. 3. Choice of direct or BIOS interfaces. All versions of CopyQM prior to version 3.00 directly accessed the dis- kette controller hardware for operation. Versions 3.00 through 3.05 used the computer BIOS to accomplish the same thing. Version 3.1 offers a choice of either the direct or BIOS interface, with the direct interface as- sumed to be the default. Many users have found that the direct hardware interface provides superior perfor- mance over the BIOS interface. 4. Persistent CQMenu options. CQMenu now "remembers" many of the more common option choices made during previous sessions. _________________________________________________________________ Command Line Syntax 21 This represents only a partial list; there are many other changes, refinements and additions to CopyQM. Memory Usage CopyQM reads a master diskette or image file in one uninterrupted pass. Because most diskette formats can hold more data than can be contained in conventional memory on a system, CopyQM uses a variety of methods to store the "overflow" data: 1. As much data as can be contained in conventional memory is first read. Sufficient memory must be available for CopyQM execution; this can be as little as 256K. 2. A test for extended memory is then performed. Extended memory, if it is to be used by CopyQM, must be managed by a high memory manager, such as Microsoft's HIMEM.SYS. Unmanaged high memory will not be used by CopyQM. If the NOXMS command line option has been specified, no check is made for extended memory. 3. After extended memory has been filled, or if extended memory could not be located, a test for expanded memory is performed. Expanded memory, or EMS, must conform to the Lotus/Intel/Microsoft Expanded Memory Specification level 4.0 or later. If the NOEMS option has been specified on the command line, no check is made for ex- panded memory. 4. Finally, after expanded and extended memory have been used, a search for an environment variable named CQTEMP is performed. If found, it is taken to specify a drive and directory on which a temporary file can be created. If the CQTEMP variable cannot be located, a search for an environment variable named TEMP is per- formed and the drive and path specified by it is used. If neither environment variable is found, the first hard disk partition is used that has enough free space available for the temporary file. _________________________________________________________________ 22 Differences 5. If sufficient memory or disk space cannot be located, the master diskette or image file is rejected by CopyQM and a NOT ENOUGH MEMORY error message is displayed. When converting between formats, CopyQM writes a temporary image file and then reads it back into memory. A sufficient amount of hard disk space must be available for the temporary image file and any overflow storage required for the master diskette image. Diskette Image Files CopyQM has the ability to save the information contained on a dis- kette in the form of a hard disk file called a diskette image file. Diskette image files contain all of the data that would be processed in the course of a diskette copy, along with other in- formation necessary to construct a copy. After an image file has been created, it can be read later by CopyQM to produce copies of the original master diskette. Diskette image files are unlike "archive" files in that in- dividual diskette files cannot be manipulated. However, image files of non-DOS diskettes can be created. WHen CopyQM options are called out using the DOS command line in- terface, the RECORD and PLAYBACK options respectively are used to specify creation and reading of diskette image files. Format conversion can be performed when creating a diskette image file, as well when reading it as a master image. In other words, an image file corresponding to a 2.88M diskette can be created from a 360K diskette, even though the system used to create the file does not support 2.88M diskettes. An on-screen editor is provided for adding comments to an image file. Image files contain a 32-bit Cyclical Redundancy Checksum (CRC) which is computed from the data read from the master dis- kette. This checksum is re-computed and verified when the dis- kette image file is read back. _________________________________________________________________ Memory Usage 23 Although a limited amount of data compression is performed within a diskette image file, it is recommended that sufficient hard disk space be reserved equal to the capacity of the master dis- kette when diskette image files are created. Copying Modes CopyQM contains logic to optimize copying of DOS and Apple Macin- tosh high-density diskettes. A master diskette is processed by CopyQM only as far as the highest cylinder containing active data. While this ensures that all active data is copied, areas of a diskette which contain erased data may not be copied. Nor- mally, this presents no problem and the result is a fully func- tional diskette. However, some copy-protected products may record their protection information as erased data. When the DOS utility DISKCOMP is used to compare a master dis- kette with a copy, it may report mismatches when erased data from the master diskette is compared with the corresponding areas on the copy. If all areas of a diskette are to be copied, "blind" mode copying may be specified. In this mode of operation, CopyQM does not at- tempt to interpret the data being copied and no "shortcuts" are taken. Usually, "blind" mode is specified when a diskette was not created by a DOS or Apple Macintosh system. However, "blind" mode may also be used for DOS and Macintosh diskettes when it is desired that all data contained on a master diskette be trans- ferred to the copies. Note that format conversion, described below, operates dif- ferently in "blind" mode. _________________________________________________________________ 24 Image Files Format Conversion CopyQM can be used to translate one diskette format to another. For example, a 360K 5.25" diskette can be converted to a 3.5" 1.44M diskette. This conversion can be specified by a CQMENU menu choice or by the CopyQM CONVERT command-line option. WHen DOS diskettes are being copied, CopyQM adjusts track sizes and File Allocation Table (FAT) lengths and updates the informa- tion contained in the boot sector. The resulting combination of active data and new system tables must fit on the new format specified. Thus, a 1.44M diskette containing less than 360K of data can be copied to a 360K diskette. When non-DOS diskettes are being copied in "blind" mode, conver- sion is performed differently. Data from the master diskette is "re-packed" to fit the new track size; no other adjustments are performed. A special case occurs when conversion of a DOS 1.2M or 1.44M master to a 2.88M format is specified. Because of limitations in the conversion process, the result will exhibit only 2.04M of available data space, rather than the entire 2.88M. CopyQM also supports non-conversion copies between some formats. This capability, undocumented in previous versions, allows copy- ing of some smaller formats to larger ones without any processing of the data. For example, a 1.2M 5.25" diskette can be copied to a 1.44M 3.5" diskette. The result is a 3.5" 1.2M diskette. Copy Verification Several methods of checking the accuracy of data are offered by CopyQM. CQMenu offers a menu selection for each verification method. By default, CopyQM checks the part of a diskette known to contain active data for readability by reading the copy diskette and dis- carding the data. The part of the copy not containing active data is not checked. This corresponds to the VERIFY=DATA command line option. _________________________________________________________________ Format Conversion 25 An entire diskette can be checked for readability by specifying the VERIFY=ALL option on CopyQM's command line. Note that the accuracy of the copied data is not checked, but only the readability of the data. Read-back checks can be completely disabled by specifying VERIFY=NONE. This option is usually selected when the speed of the copy operation is more important than the accuracy of the copy. A byte-by-byte compare can also be specified by use of the COM- PARE command-line option. Comparison is performed only on the part of the diskette containing active data. Inactive areas can be checked for readability only. Checking Copies An option not covered by a CQMenu selection alters the basic operation of CopyQM. If the CHECK option is specified on the CopyQM command line, copies are not formatted or written. In- stead each copy is compared with the data from the master dis- kette. This option is useful when the validity of a number of copies needs to be checked against a master standard copy. Audible Signals CopyQM provides several audible "cues" during its operation: 1. A high-pitched "warble" that indicates that an opera- tion has been successfully completed. This tone is sounded after a master diskette has been read, after after each copy has been written, and after keyboard entries have been selected. 2. A low-pitched "beep" that signals an error condition. This tone is sounded after unsuccessful disk read or write operations, and when an erroneous keyboard entry is made. _________________________________________________________________ 26 Verification 3. A medium-pitched "warble" that signals a need for atten- tion. This tone can be selected as an option and is sounded after intervals of 20 seconds of inactivity. The command line option for this tone is NAG. All audible signaling may be disabled by CQMenu menu selection or by the SILENT command line option. "Smart" Formatting By default, CopyQM formats all copies before writing data. However, it is possible to direct CopyQM to check for pre- formatted media before writing. This option is available by a CQMenu choice, or by the SMART command line option. "Smart" mode attempts to write data without first formatting a copy. If writing and verification succeed, the inactive area on the copy is skipped. However, if an error is detected while writ- ing active data, all remaining tracks on the diskette are for- matted before being written. "Smart" mode can result in substantial time savings over normal format-then-write operation. Quick Mode Copying When copies of partially full DOS diskettes are made, a con- siderable increase in copying speed can be obtained by specifying the QUICK command-line option. When this option is selected, only the part of the master diskette that contains active data is copied or formatted. However, when using unformatted blank diskettes, it is important to realize that tracks at the end of each diskette will not be formatted. This may make it impossible for users of the copies to successfully write to the copies or duplicate them using the DOS DISKCOPY utility. This option is not available from within CQMenu. _________________________________________________________________ Audible Signals 27 Display Color Set In some instances, it may be desired that CopyQM show all dis- plays with a black-and-white (monochrome) color palette. This may be specified by means of the MONO command line option. This option is not available from CQMenu, but if CQMenu is started with the "MONO" command-line option, the monochrome color set will be used for CopyQM also. A monochrome color set is particularly useful when portable sys- tems with liquid crystal displays (LCD) are used. Many of these systems support color as shades of gray, rather than actual colors. A monochrome color set will be found to be more readable in this case. Status Messages CopyQM displays the following status messages during the process of reading and writing diskettes: DRIVE NOT READY Meaning: The drive has become not ready during reading or writing. This is usually the result of opening the drive door or removing the diskette from the drive. The current read or write operation is canceled and the operation is retried from its beginning. INSERT MASTER Meaning: CopyQM is awaiting insertion of the master dis- kette. If there is a diskette already in the diskette drive, the diskette should be removed and re-inserted into the drive to signal that the correct diskette has been in- serted. READY TO WRITE Meaning: CopyQM has noticed that the last diskette written in this drive has been removed. A blank diskette may be in- serted in the drive, but the message will not change until CopyQM is ready to write to the drive. _________________________________________________________________ 28 Quick Mode INSERT BLANK Meaning: CopyQM is awaiting insertion of the next blank copy diskette. This message persists after the blank dis- kette has been inserted and is changed only when writing has begun on the drive. INSERT COPY Meaning: This message occurs only when CopyQM is being run with the CHECK option. The next diskette copy to be verified should be inserted. This message is not removed until verification of the copy has actually begun. ANALYZING Meaning: CopyQM has begun reading the master diskette and is evaluating its structure and contents. READING Meaning: The structure of the master diskette has been determined and data is being read and stored for later writ- ing. WRITING Meaning: CopyQM is in the process of writing a copy. No formatting is being performed. WRITING WITH FORMAT Meaning: CopyQM is formatting and writing a copy. RECORDING Meaning: A diskette image file is being written to disk. _________________________________________________________________ Status Messages 29 CONVERTING Meaning: Diskette data is being converted to the requested format. CHECKING Meaning: This message occurs only in CHECK mode. CopyQM is reading a diskette copy and comparing the data with the master. REMOVE MASTER Meaning: CopyQM has finished reading the master diskette. The diskette should be removed from the drive. RE-INSERT MASTER Meaning: The current diskette should be removed from the drive and inserted again. CopyQM is attempting to ensure that the diskette in the drive is, in fact, the diskette to be copied. READ ERROR Meaning: The master diskette did not read without errors. Reading of the same diskette can be attempted again, or a new master diskette may be inserted. NOT DOS DISK Meaning: The boot sector on the master diskette does not conform to any DOS standard layout. If the diskette is not a standard DOS format, it may be possible to copy the dis- kette by specifying the BLIND option. This message may also occur if the diskette contains a computer virus in its boot sector. Diskettes infected with the so-called "Stoned" virus will cause this message to be displayed. _________________________________________________________________ 30 Status Messages OUT OF MEMORY Meaning: Not enough memory and hard disk storage could be located to contain the data from the master diskette. It may be possible to avoid this message by explicitly specify- ing the location of the overflow hard disk file. READ COMPLETE Meaning: The specified diskette image file has been read. A blank diskette can be inserted into the drive for copying. NOT PROTECTED Meaning: The WRITEPROTECT option has been specified and the master diskette is not write-protected. COMPLETE - REMOVE Meaning: A diskette copy has been successfully completed and can be removed from the diskette drive. DISK UNUSABLE Meaning: Writing the diskette failed because of an un- recoverable error. Either the wrong media type (high den- sity instead of low density) has been used or the diskette contains a permanent flaw. VERIFIED - REMOVE Meaning: This message occurs only when CopyQM is being run with the CHECK option. The diskette copy has been success- fully verified and may be removed from the drive. PROTECTED--TRY AGAIN Meaning: Writing has failed on a diskette because the dis- kette was write protected. The diskette should be re- inserted after the diskette has been write-enabled. _________________________________________________________________ Status Messages 31 BAD IMAGE FILE Meaning: CopyQM has detected an error in the diskette image file being read. No recovery from the error is possible. This message can occur if a version of CopyQM prior to 2.10 was used to create the image file. FILE WRITTEN Meaning: The requested diskette image file has been written and the master diskette can be removed from the drive. OUT OF FILE SPACE Meaning: There was not enough hard disk space to success- fully create the requested diskette image file. This mes- sage also occurs when there is insufficient hard disk space to hold temporary files when format conversion has been re- quested. TARGETTE TOO SMALL Meaning: After the requested format conversion was per- formed, CopyQM determined that the data from the master dis- kette would not fit on a single diskette of the requested format. The ICOMMENT Utility ICOMMENT can be used to add comments to diskette image files or edit comments already contained in image files. In addition, ICOMMENT adds or re-computes the Cyclical Redundacy Checksum (CRC) for image file data. To run ICOMMENT, the following command format is used: ICOMMENT file-list _________________________________________________________________ 32 Status Messages Where "file-list" represents a diskette image file name or the name of several diskette image files. Wildcard file specifiers of "*" and "?" are allowed. In addition, the switch "/MONO" can be used. For example, the command: ICOMMENT /MONO MYIMAGE.* selects a monochrome color palette and processes all image files satisfying the file specification "MYIMAGE.*". ICOMMENT is included only with registered and Plus versions of CopyQM. Specifying a Diskette Configuration Normally, CopyQM can determine a system's configuration without intervention. However, there are cases where add-on diskette adapters make it impossible to accurately sense the system setup. To determine if CopyQM has correctly sensed your system's con- figuration, use the VIEWCONF command that is included with CopyQM. If necessary, a text file, named DISKETTE.CFG can be prepared using any text editor or word processing program in non-document mode. This file can be placed anywhere in the DOS command search path and will be automatically located by CopyQM. The layout of the configuration file is straightforward. Each line in the file begins with the letter of the diskette drive being described, followed by a colon (:). The rest of the line contains keywords and numeric values which specify the configura- tion for that drive. Each item on the line is separated by one or more spaces. In most cases, keywords can be abbreviated. A configuration file line can contain any of the following keywords. The minimum abbreviation for each keyword is shown in parentheses: 360K (3) specifies a 5.25" 360K drive. 720K (7) specifies a 3.5" 720K drive. Most utilities also support the less common 5.25" 720K quad-density drive. _________________________________________________________________ The ICOMMMENT Utility 33 1.2M (1.2) specifies a 5.25" 1.2M drive. 1.44M (1.4) specifies a 3.5" 1.44M drive. 2.88M (2.8) specifies a 3.5" 2.88M drive. 8INCH (8) specifies an 8" drive. Note that the drive type must be specified. BIOS (B) specifies the BIOS drive number for the drive. The word BIOS is followed by a a number between 0 and 127. This number is also the same one used for the /D: parameter when DRIVER.SYS is used to support the drive in the system's CONFIG.SYS file. PORT (P) specifies the base I/O port of the adapter con- nected to the drive. The first or primary adapter is always described by the number 3F0H (observe the "H" at the end of a hexadecimal number.) Secondary adapters are usually ad- dressed by the number 370H and sometimes by 360H or 3E0H. If not specified, a PORT value of 3F0H is assumed. UNIT (U) specifies the physical unit number of the drive on the adapter. This unit number must be within the range of 0 to 3 and should not be confused with the BIOS unit number. DMA (DM) specifies the Direct Memory Access channel which services the adapter. If omitted, DMA channel 2 is assumed. INTERRUPT (I) specifies the system interrupt which services the adapter. If omitted, interrupt 6 is assumed. SEEK (S) specifies the track-to-track stepping time of the drive in milliseconds. If omitted, 6 milliseconds is as- sumed. CHANGE (CH) specifies that the drive possesses diskette change detection circuitry. If this term is omitted, the drive is assumed not to support change detection. Usually, 1.2M, 1.44M and 2.88M drives have change detection cir- cuitry; 360K, 720K and 8 inch drives do not. _________________________________________________________________ 34 Specifying a Configuration DUAL (DU) is applicable for 1.2M 5.25"drives only. Some inex- pensive secondary adapters require that 1.2M drives be con- figured for dual-speed operation in which the spindle motor spins at 360 revolutions per minute for high-density opera- tion and 300 revolutions per minute for low-density opera- tion. If omitted, normal single-speed operation is assumed. COMPATICARD (CO) specifies that the drive is connected to a MicroSolutions Compaticard Itm or Compaticard IItm adapter. If the Compaticard IVtm is being used, this term should not be specified. DAA (DA) indicates that the drive is connected to an IBM PS/2 Diskette Adapter/A. This adapter is present on external drives on Microchannel systems only and is assumed not to be present. A number is required to follow the following words: BIOS PORT UNIT DMA INTERRUPT SEEK A number is assumed to be a decimal value unless suffixed by the letter "H" which indicates a hexadecimal quantity. Thus, 1000 and 3E8H refer to the same quantity. Here is an example of a DISKETTE.CFG file: A: BIOS 0 UNIT 0 1.44M CHANGE B: BIOS 1 UNIT 1 1.2M CH Q: BIOS 4 PORT 370H UNIT 0 360K There are two other items which may start a configuration line. DEFAULT: initializes the configuration to the values that would be obtained if automatic configuration sensing were to be per- formed. Use of DEFAULT is useful if automatic sensing has cor- _________________________________________________________________ Specifying a Configuration 35 rectly sensed all but one or two drives. For example, suppose that the configuration given above is correctly sensed, with the exception of drive Q:. The DISKETTE.CFG file could be stated as: DEFAULT: Q: BIOS 4 PORT 370H UNIT 0 360K DEFAULT must appear as the only item on a line. NOTE: causes the remainder of a line to be ignored. Comments may be inserted into the DISKETTE.CFG file in this manner. For ex- ample: NOTE: Automatic sensing gets everything but NOTE: drive Q: connected to a special second NOTE: adapter. DEFAULT: Q: BIOS 4 PORT 370H UNIT 0 360K NOTE: This is the end of the configuration file. ---------------------------------------------------------------- Certain terms used in this document are trade marks of one or more of the following companies: Apple Computer, Microsoft Cor- poration, International Business Machines Corporation, Quarter- deck, Inc., Microsolutions, Inc., Digital Research Inc., The Software Link, Inc. _________________________________________________________________ 36 Specifying a Configuration
