-
- *** Accessing TransCD with a DOS Drive Letter
-
- Accessing TransCD requires loading the TransCD device driver (TCD-IDE.SYS)
- and executing the Microsoft CD-ROM Extension (MSCDEX.EXE) which assigns a
- DOS drive letter. To do this, you need to perform one of the following:
-
- 1. Permanent Installation --
- TCD utility allows normal installation of the TransCD software onto the
- internal hard drive. It makes changes to the CONFIG.SYS and AUTOEXEC.BAT
- files. A reboot is required to load the device driver and MSCDEX.
-
- Syntax: TCD
-
- 2. Dynamic Loading --
- TCDGO command allows loading the device driver and MSCDEX dynamically
- without first installing the software via TCD. It does NOT change any
- of the host system setup. No reboot is required.
-
- Syntax: TCDGO [timing] [U] [B]
-
- timing timing adjustment for device driver to match parallel port
- characteristics. Range: 0 - 99; Default = 0.
- U force parallel port to work uni-directionally.
- B force parallel port to work bi-directionally.
-
- See following sections for detail on timing adjustment and 'U/B' option.
-
- 3. Boot from Diskette --
- TCDBOOT utility allows creating a boot disk out of this same diskette for
- loading the device driver and MSCDEX.
-
- Syntax: TCDBOOT [timing] [U] [B] (same as TCDGO)
-
- --------------------------------------------------------------------
-
- *** MANUAL INSTALLATION AND UN-INSTALLATION
-
- This section describes how to install and un-install TransCD system
- software manually if a user needs or prefers to do so.
-
- In order to use TransCD, user needs to install the following software.
-
- (1) TCD-IDE.SYS into CONFIG.SYS
- (2) MSCDEX.EXE into AUTOEXEC.BAT
-
- The utility program, TCD.EXE, in installation diskette can perform the
- above installation automatically. However, a user can manually do it
- if it is perferrable or if he/she wants to change options.
-
- To un-install, remove the driver and MSCDEX statements from config.sys
- and autoexec.bat. Also, remove TransCD software from boot drive.
-
-
- *** TCD-IDE.SYS ***
- Syntax:
- In CONFIG.SYS,
- DEVICE=C:\TCD-IDE\TCD-IDE.SYS /D:TCD-IDE$ [/U] [/B] [/T:<t>]
- Description:
- /D:TCD-IDE$ specifies the driver signature of this CD-ROM device
- driver. This name is used by MSCDEX.EXE in the /D: switch to match for
- service channel.
- /U option forces the device driver to operate in the uni-directional
- mode regardless of the printer port hardware.
- /B option forces the device driver to operate in the bi-directional
- mode if the printer port hardware supports it. Otherwise, it is equivalent
- to the /U option.
- If neither /B nor /U option is specified (default), the device driver
- will AUTOMATICALLY detect whether the printer port hardware is uni-directional
- or bi-directional or EPP (Enhanced Parallel Port).
- In each mode, the driver will operate in full speed to take
- advantage of the highest performance offered by the hardware. However,
- under certain circumstances, the operation may not be satisfactory and the
- timing may need to be adjusted. /T option allows manual setting of the timing
- between the device driver and the printer port. When /T option is not specified
- (default) or set to 0, the driver will run at full speed. When /T option is
- specified, <t> indicates the MANUAL-TIMING parameter. The larger the value of
- <t> is, the slower the system becomes. The range is from 0 to 255.
- The /T option has no effect on the EPP mode operation, it always
- operates at the fastest possible speed.
- In certain rare cases, if an EPP port does not work properly, /B or
- /U option can be specified to force bi/uni-directional mode operation.
- And if a bi-directional port does not work properly,
- /U option can be specified to force uni-directional mode operation.
-
- Example:
- Enable AUTO-DIRECTIONAL mode
- DEVICE=C:\TCD-IDE\TCD-IDE.SYS /D:TCD-IDE$
-
- Enable AUTO-DIRECTIONAL mode, timing parameter to 5
- DEVICE=C:\TCD-IDE\TCD-IDE.SYS /D:TCD-IDE$ /T:5
-
- Set UNI-DIRECTIONAL mode, full speed
- DEVICE=C:\TCD-IDE\TCD-IDE.SYS /D:TCD-IDE$ /U
-
- Set BI-DIRECTIONAL mode, timing parameter to 5
- DEVICE=C:\TCD-IDE\TCD-IDE.SYS /D:TCD-IDE$ /B /T:5
-
-
- *** MSCDEX.EXE Provided by Microsoft ***
-
- Syntax:
- In AUTOEXEC.BAT,
- MSCDEX /D:driver [/D:driver2 ...] [/E] [/K] [/S] [/V] [/L:letter]
- [/M:number]
- Description:
- /D:driver1 [/D:driver2]
- Specifies the driver signature of the first CD-ROM device driver.
- The driver1 parameter must match the parameter specified by the /D
- switch on the CONFIG.SYS command that starts the corresponding
- CD_ROM device driver.
- The MSCDEX command must include at least one /D switch. To install
- additional CD-ROM device drivers, specify an additional /D switch
- for each device driver.
- /E
- Specifies that the CD-ROM driver be allowed to use expand memory,
- if available, to store sector buffers.
- /K
- Specifies that MS-DOS should recognize CD-ROM volume encoded in
- Kanji. By default, MS-DOS does not recognize Kanji CD_ROM volumes.
- /S
- Enables Sharing of CD-ROM drives on MS-NET or Windows for Workgroups
- servers.
- /V
- Directs MSCDEX to display memory statistics when it starts.
- /L:letter
- Specifies the drive letter to assign to the first CD-ROM drive.
- If you have more than one CD-ROM drive, MS-DOS assigns additional
- CD-ROM drives subsequent available drive letters.
- /M:number
- Specifies the number of sector buffers.
-
- Example:
- C:\TCD-IDE\MSCDEX /D:TCD-IDE$
-
- C:\TCD-IDE\MSCDEX /D:TCD-IDE$ /L:S
-

-
- *** Note on LASTDRIVE setting in CONFIG.SYS
-
- User may have to set LASTDRIVE, in CONFIG.SYS, to high number if TransCD
- is assigned to a higher number than that current system allows to.
- Refer to DOS user's guide for LASTDRIVE setting.
-
- ____________________________________________________________________
-
- *** Note on DAISY-CHAIN multiple FIT parallel devices
-
- If there is TransDisk 3000, you can only daisy chain up to 2 units per
- printer port.
-
- If ther is no TransDisk 3000, you can do so up to 4 units per printer
- port.
-
- There is no restriction in what order the devices should be daisy chained.
-

-
- *** Note on Printer Port Compatibility (1)
-
- If you cannot access TransCD and you have already followed the
- troubleshooting instruction in the User's Guide, it is most likely
- that your printer port may not be fully IBM compatible. In this case,
- Try /B or /U option, and/or adjust the timing by using /T option mentioned
- above and reboot the system. Also see the note below.
-
- ____________________________________________________________________
-
- *** Note on Printer Port Compatibility (2)
-
- If you are using IBM PS/2 (or similar) machines which has DMA capability
- on the printer port, e.g., PS/2 models 56, 57, 76, 77 and 90XP, you MUST
- disable the "DMA Arbitration Level" of the printer port to use TransCD.
-
- In order to do so, you can enter configuration (CMOS) setup mode at
- the system boot time. On PS/2 model 56, enter Ctl+Alt+Ins when cursor
- moves from upper left corner to right upper corner at system boot.
- Please refer to PS/2 User's Handbook for additional information.

- *** Dynamic Driver Loader
-
- DLD.COM allows a user to load TransCD driver at DOS prompt.
- DLD.COM works on MS DOS 3.x, 4.x, 5.x, and 6.x. It may or may not work on
- other DOS operating systems.
-
- Syntax:
- DLD C:\TCD-IDE\TCD-IDE.SYS /D:TCD-IDE$
-

-
- *** Advise on potential printer port I/O address conflict from other I/O card
-
- In some rare case, some I/O adapter, especially LAN adapters, causes
- I/O address conflict to printer ports. These I/O adapters respond to
- full 32(20H) I/O addresses starting from its base I/O address, for instance,
- it occupies 360H-37fH when I/O address 360H is selected. In the example,
- it will cause conflict with printer port 378H. This problem is due to
- design failure of that particular I/O adapter. Nothing DOS or TransCD
- can do. To get around the problem simply uses the other I/O address
- for that adater or printer port. Since I/O adapters allow a user to
- have many choices for I/O address, please try not to use I/O address of
- 3A0H, 360H, and 260H. It will make your potential printer I/O addresses
- 3BCH, 378H, and 278H, very safe.
-
- The common sympton for the above I/O conflict is that TransCD hangs or
- runs with extremely poor performance.

- *** How to use TransCD on a OS/2 system
-
- Before an OS/2 native driver is available for TransCD, the following
- procedure can be used to access TransCD on a DOS session under OS/2.
- Thanks to Mr. Doug Azzarito of IBM, an excellent technical support,
- accessing TransCD under OS/2 is now possible.
-
- The following procedure describes how to access the TransCD from OS/2
- by using a "specific DOS session." This is a feature in OS/2 that allows
- you to boot a session of "real" DOS mode while running OS/2. To set this
- up, do the following:
-
- * Hardware:
- If you are using non-PS/2 machine, no hardware setup is necessary.
- If you are using PS/2 (or similar) machines which has DMA capability
- on the printer port, e.g., PS/2 model 56, you MUST disable the DMA
- of the printer port to use TransCD.
-
- In order to do so, you can enter configuration (CMOS) setup mode at
- the system boot time. On PS/2 model 56, enter Ctl+Alt+Ins when cursor
- moves from upper left corner to right upper corner at system boot.
- Please refer to PS/2 User's Handbook for additional information.
-
- * Software:
- (1) Create a bootable DOS diskette that will load the TransCD driver and
- MSCDEX command. Boot from this diskette to make sure everything
- works properly.
- (2) Boot OS/2, and insert the bootable DOS disk in drive A:
- (3) Copy the file \OS2\MDOS\FSFILTER.SYS to A:
- (4) Add the line: DEVICE=FSFILTER.SYS as the first line in the CONFIG.SYS
- on the bootable DOS diskette.
- (5) Open the COMMAND PROMPTS folder (inside the OS/2 SYSTEM folder).
- you will see a "DOS FROM DRIVER A:" object. Start that object, which
- will boot the DOS disk in drive A:.
-
- From this DOS session, you will have access to the TransCD. No other
- session will see the TransCD, and all printing from other sessions will
- be held in the spooler until the DOS session is closed.
-
- The VMDISK command can make an "image" of this boot floppy, so you can start
- a TransCD session without inserting the floppy. Type HELP VMDISK from
- an OS/2 command prompt for details.
-
- * Caveat:
-
- Due to multitasking environment of OS/2, TransCD performance on this
- DOS session is far below that in actual DOS environment.
-

- *** Attention IBM PC-XT users
-
- If you encountered difficulty when trying to access the TransCD on an IBM
- PC-XT (or any Intel 8088/8086 compatible) equipped with EPP port, specify
- /B or /U option to the device driver (TCD-IDE.SYS), and reboot the system.
