-------------------------------------------------------------------- Norton Utilities 6.01 READ.ME file -------------------------------------------------------------------- This file contains compatibility information, late-breaking news, and feature updates which do not appear in the manual. If you would like to print this file, at your DOS prompt type: LP READ.ME /H60 The "Getting Started" chapter of the User Guide states that this READ.ME file will be available as part of the on-line help system. Instead, this file will remain a separate file on disk, to ensure that the information is the most current available. Changes from prior versions of Norton Utilities ========================================================= Some programs from previous versions of Norton Utilities have been combined into other programs in version 6.0. These changes are noted in the following list: Version 4.5 Program Version 6.0 Program ----------------------- --------------------------- DI - Disk Information Sysinfo DT - Disk Test NDD LD - List Directory NCD NU - Norton Utilities DiskEdit, UnErase, DiskTool QU - Quick UnErase UnErase TM - Time Mark NCC UD - UnRemove Directory UnErase VL - Volume Label NCD WIPEFILE WipeInfo WIPEDISK WipeInfo The Norton Integrator (NI) program from version 4.5 has been greatly enhanced and is now called "NORTON." The FILESAVE.EXE program from the Norton Utilities 5.0 has been renamed to EP.EXE, and is now known as "Erase Protect." The File Info (FI) program is no longer available, but a more powerful version is available through the DESCRIBE command found in NDOS. New Features ========================================================= NCD --- A new command has been added to the "Disk" menu in NCD. The "Free Space" command will display the total size, space used, and available space of the current drive. Questions and Answers ========================================================= Installation Errors ------------------- If, for some reason, your are unable to install the Norton Utilities on your system using the Install program, they can be installed manually. The following steps will install the Norton Utilities: 1) Create a directory on your disk to receive the Norton Utilities programs, if you don't have one already. For example, to install the Norton Utilities in a directory called NORTON on your hard disk, use the command MD C:\NORTON 2) Copy the contents of the distribution diskettes to your Norton Utilities directory. For example, assuming you are installing from drive A:, use the command COPY A:*.* C:\NORTON for each of the distribution diskettes. 3) There are various files stored in compressed form on the distribution diskettes. See the section "Archive File Extraction Errors" below to extract the compressed files. Note that you have already copied the archive files to the destination directory, and can run the extractions from there. 4) Now your system must be configured to run the Norton Utilities whenever you want them. To have the Norton Utilities Configuration program do this for you, make sure you are in the directory with the Norton Utilities, for example use the commands C: CD C:\NORTON Then enter the command NUCONFIG /$INSTALL and follow the instructions on the screen. You can look in the Installation Guide for more details on the Configuration stage of installation. 5) Finally, if you have made any changes to your system configuration in step 4, you will need to reboot your computer for these changes to take effect. 6) You are now ready to use the Norton Utilities! Archive File Extraction Errors ------------------------------ The Help files and the Windows icons supplied with the Norton Utilities are compressed into archive files. While running Install, if you encounter an error during the extraction of the programs from the archive file, first try uncompressing them manually. This is done by launching the archive file with the destination drive and path name where you wish to install the Norton Utilities: <Source Disk:Archive File Name> <TargetDisk:\Directory>. For example, to extract the help files manually, use the following command: A:HELPARC.EXE C:\NORTON There are three archive files, whose contents are listed below: ICONARC.EXE HELPARC.EXE NDOSARC.EXE ----------- ----------- ----------- DISKEDIT.ICO NU.HLP COMPAT.DOC DISKREET.ICO TROUBLE.HLP ALIASES FILEFIND.ICO NDOS.HLP DESCRIPT.ION FILEFIX.ICO NCD.ICO NDD.ICO NDOS.ICO NORTON.ICO PETER.ICO SFORMAT.ICO SYSINFO.ICO PC-MOS ------ Symantec does not support the use of the Norton Utilities under PC-MOS. Limited testing has shown that some of the programs will work, however those which perform direct disk access are not compatible. These programs include Norton Disk Doctor, Calibrate, UnErase, Speed Disk, Disk Editor, Norton Cache, Directory Sort, WipeInfo (disk wiping only), and NCD (Prune and Graft, and Copy Tree). CMOS Error Messages ------------------- If any of the Utilities reports an invalid CMOS on a computer that doesn't have a CMOS chip, use the /NOCMOS switch on the command-line when invoking that program. Lap Top Colors -------------- To improve the viewing quality of an LCD laptop screen, at the DOS prompt you may type NORTON /LCD. During the installation process, you can configure all the Norton Utilities to use the LCD color set without having to include the /LCD switch. Video Display and Mouse Problems -------------------------------- Some EGA and VGA adapters have a quirk which causes screen degradation problems when the graphical (arrow- shaped) mouse pointer is used. If small dots appear and disappear as the mouse is moved, you should use the standard mouse pointer. Choose the Video and Mouse Options item from the Norton program's Configure menu, and set the Graphics Options to either "Standard" or "Graphical Controls." If you have trouble reading the Norton program's screens in order to change this option, type "MODE CO80" at the DOS command line to fix the display, then type "NORTON /G0" to start the program in the standard mode. Use of the DOS "FASTOPEN" program --------------------------------- Starting with version 3.3, DOS has included a program called FASTOPEN that is supposed to increase the speed of certain disk operations. WE STRONGLY RECOMMEND THAT YOU DO NOT USE FASTOPEN. FASTOPEN can cause data loss under some conditions. Some versions of DOS, and some computer vendors, install FASTOPEN by default when they set up the machine. You may have FASTOPEN installed on your computer even though you didn't put it there yourself. Many of the Norton Utilities cannot be used if FASTOPEN is installed. Norton Cache Documentation Changes ---------------------------------- There have been a number of changes to the NCACHE command line switches since the manual was printed: The manual indicates that the /INSTALL switch will use all available Extended and Expanded memory for caching under both DOS and Windows. NCACHE actually leaves 64K of Extended and/or Expanded memory free under DOS, and reduces to 25% of that amount under Windows. If using 25% would reduce the cache size to 256K or less, the cache is disabled while in Windows (reduced to 0K). The cache automatically resumes operation upon return to DOS. The manual indicates that if only one memory size is given to the /EXP or /EXT switch (e.g. /EXP=512), the cache size will be the same under both DOS and Windows. NCACHE actually uses the size specified under DOS, but reduces to 25% of that amount under Windows. If using 25% would reduce the cache size to 256K or less, the cache is disabled while in Windows (reduced to 0K). The cache automatically resumes operation upon return to DOS. If both a DOS and Windows memory size are explicitly given (e.g. /EXP=512,128), NCACHE will always use those amounts. The /QUIET switch was inadvertently left out of the manual. This switch will prevent NCACHE from displaying any messages on the screen unless there is an error. Norton Cache Compatibility Notes -------------------------------- We have attempted to make NCACHE one of the most compatible disk caching programs available. NCACHE will work with almost any hard disk supported by DOS. It is important to understand, however, that it is impossible to test any cache against all the computers and disk drives ever sold. There is simply too much variety in the PC marketplace, and very few machines are exactly alike. NCACHE integrates itself closely with the operating system and hardware, and may be effected by compatibility problems that would not show up with standard applications programs (e.g. word processors and spreadsheets). If your computer isn't 100% compatible, you may be able to run standard programs perfectly, but be unable to use NCACHE. In many cases, using the /WRITE=0 switch during cache installation will solve any compatibility problems (you can also use the NCACHE "advanced configuration" dialog in the NUCONFIG program to set the size of the write-back buffer to zero). If you have an older computer, you may also want to check with the vendor to see if a more recent ROM BIOS is available. If you are using the combination of DOS 5.0, NCACHE, and the QEMM-386 memory manager, we recommend that you obtain QEMM version 5.13 or later. Please contact Quarterdeck for an update. NCACHE only works on "normally connected" floppies. If the floppy drive requires a special interface board or a device driver, NCACHE probably won't be able to cache it. Most external drives are not supported by NCACHE. NCACHE is unable to cache a floppy drive that does not have "Change Line" support. This is a hardware feature on the drive that tells the computer when a diskette has been removed. 360K drives often do not have a change line, and thus cannot be cached. NCACHE will work fine on most other drives (1.2M, 720K, 1.44M, etc.). NCACHE will automatically determine which drives can be cached. If a drive cannot be cached, NCACHE will either report "Cannot detect media change for this drive" or simply omit the drive from its status display. In order to use Expanded Memory (EMS) with NCACHE, you must have an expanded memory manager that implements Version 4.0 of the EMS specification (sometimes called the "LIM" specification). You must also have true EMS support through hardware or through a driver such as QEMM. You cannot use a software emulator like Above Disc. If you have an older memory manager, check with your memory board manufacturer to see if an upgrade is available. In most cases all you'll need is new memory manager software; no hardware changes will be required. NCACHE will normally ignore EMS memory if you don't have the correct memory manager. If you run NCACHE with no parameters it will simply skip over EMS and try to use extended or conventional memory instead. If you provide an explicit EXP= parameter, you will receive an error message and NCACHE will not install itself. NCACHE is compatible with IOMEGA removable disk drives only when using Version 7.0 or later of the RCD.SYS device driver. This version of the driver is compatible with all types of IOMEGA disk drives, and both ISA and MicroChannel computers. Please contact IOMEGA for an upgrade if you are using an earlier version. Only one disk cache program can be loaded on the computer at once. You must remove any other cache (e.g. SMARTDRIVE or PC-KWIK) before installing NCACHE. Multiple disk cache programs may conflict with each other and corrupt disk data. NCACHE is not compatible with Zenith DOS 3.3 Plus when any hard disk partitions are larger than 32MB. There is a potential incompatibility between NCACHE delayed writes and certain versions of the American Megatrends (AMI) 486 BIOS. The most recent version of the AMI BIOS appears to be OK, but older versions may exhibit a random lock up when delayed writes are used. If you experience a lock up, simply disable the delayed writing feature with the /WRITE=0 command line switch during cache installation. You may also want to contact your system vendor to see if a more recent BIOS is available for your computer. If you use a program that automatically reboots your computer, there is the potential that data stored in the cache will not be written to disk. The BE REBOOT command automatically resets NCACHE, but other rebooting programs will not. We recommend either changing to use BE REBOOT, or using an NCACHE RESET command right before the command that reboots the system. On most computers, NCACHE will trap the CTRL-ALT-DEL sequence used to reboot the system. If there is unwritten data stored in cache buffers, NCACHE will write it to disk before rebooting. Some older 8088-based computers and some 386 memory managers prevent NCACHE from trapping CTRL-ALT-DEL. If your computer has this problem, you must either obtain a ROM BIOS upgrade, switch memory managers, or disable the NCACHE delayed writing feature. Delayed writes can be disabled by using the command line switch /WRITE=0 during cache installation. When using certain 386 memory managers, Windows may not function properly if there is less than 64K of free Extended and/or Expanded Memory. If you use the /INSTALL switch, NCACHE will automatically leave 64K memory free. If you set the cache size manually using the /EXT or /EXP switches, you need to ensure that at least 64K of memory will be free. Some computers appear to require more than 64K of free memory; if Windows will only run in the Real Mode, or returns to DOS immediately after displaying its logo screen, try leaving more free memory. Please note that this problem is not just related to NCACHE. If you have a RAM disk or other drivers using Extended or Expanded memory, you must also ensure that at least 64K is free before running Windows. If you will never run Windows, you may use all available memory for NCACHE. Ventura Publisher Version 2.0 Standard Edition has problems working with many drivers and TSR's, including NCACHE. If you encounter "Internal Error 19" dialog boxes, you need to upgrade to Version 3.0 or later of Ventura Publisher. Some anti-virus products can corrupt device driver files, including NCACHE. The Norton Anti-Virus DOES NOT have this problem, and is fully compatible with NCACHE. The products that have a problem are those that directly modify .EXE files to store checksums or other data. Note that NCACHE is not the only driver this may effect. Any driver file with an EXE extension can be corrupted, including the SETVER.EXE driver in DOS 5.0. If you are unable to boot your system because of an NCACHE compatibility problem, you can prevent NCACHE from installing by holding down the CTRL key as it is loading. UnErase ------- When in the View File Window, to Scroll Left, use CTRL+Left Arrow Key to Scroll Right, use CTRL+Right Arrow Key WipeInfo -------- A change was made to the "government wipe" switch after the manual was printed. The manual says this switch is called /Gn. It has been renamed to /GOVn. This avoids a conflict with the switches used to select video modes. Diskreet -------- DISKREET is incompatible with certain disk partitioning systems and with some OEM versions of DOS. DISKREET can create NDISK's on any disk partition under 32MB. If the partition is larger than 32MB, it must be accessed using DOS version 4.0 or later, or DOS version 3.31 from Compaq. The maximum size of a single NDISK is 32MB, even on versions of DOS that support large disk partitions. You can create multiple NDISK's if you need to secure more than 32MB of data. OEM versions of DOS such as Zenith DOS 3.3 Plus or Wyse DOS 3.21 are not compatible with DISKREET. Partitioning systems like Disk Manager and SpeedStor may have compatibility problems; it will depend on the size of the partition and the physical layout of the hard disk. We recommend testing DISKREET with your partitioning software before storing valuable data on an NDISK. If there are going to be problems, they should manifest themselves immediately. NDOS ---- NDOS is a complete replacement for COMMAND.COM, and is compatible with DOS versions 2.1 and above, as well as the OS/2 DOS compatibility box. Compatibility issues involving NDOS can be found in a file called COMPAT.DOC, located in the directory in which the Utilities were installed. The NDOS FREE command will return incorrect information for Novell Netware volumes greater than 512MB. This is actually a bug in the network shell and not a problem with NDOS. The Netware CHKVOL command can be used on network drives to obtain accurate free space information. The NDOS REN command is unable to rename directories on Novell Netware servers. This is actually a bug in the network shell and not a problem with NDOS. The Netware RENDIR command can be used instead. NDOS will use ANSI escape sequences to control screen colors if an ANSI console driver is loaded (ANSI.SYS). NDOS can't always determine when an ANSI driver is available, particularly if the Novell Netware shell is loaded. If you know you have an ANSI driver, but NDOS doesn't recognize it, the command SETDOS /A1 will force NDOS to believe that the driver is available. This is a good command to include in your NSTART.BAT file. The batch file example on page 20-9 of the User Guide is shown with a filename of TIMER.BAT. This name will conflict with the internal TIMER command in NDOS. To try this example you must either select a different filename, or execute it using COMMAND.COM. Unzapping dBASE Files --------------------- FileFix may have problems when unzapping a dBASE file when Erase Protect is on. The original of the zapped file may be in the TRASHCAN (dBASE creates a new copy of the file, saving only the header, then deletes the original file). FileFix does not currently check the TRASHCAN for zapped files. However, UnErase can be used to recover the original file. Hard Disks with More Than 1024 Cylinders ---------------------------------------- The Norton Utilities Version 6.0 provides limited support for hard disks with more than 1024 cylinders. This feature is available only on drives which are using Ontrack's Disk Manager or Storage Dimension's SpeedStor. The following limitations apply: Calibrate will not perform a Low-Level Format on any DOS partition on a drive with more than 1024 cylinders. It also will not test or optimize any DOS partition which lies BEYOND the 1024 cylinder boundary. NDD will state that DOS partitions which lie BEYOND the 1024 cylinder boundary are device-driven. Safe Format can't format any DOS partitions which lie BEYOND the 1024 cylinder boundary. Use of ALT key tap to activate pulldown menus --------------------------------------------- The Norton Utilities normally uses ALT key taps to activate its pulldown menus. This is automatically disabled under DESQview, because the default DESQview configuration uses ALT to to bring up its own control panel. If you have an ALT key conflict with a TSR other than DESQview, you can use the /NOALTKEY command line switch with any of the Norton Utilities programs. Multitasking Environments ========================================================= In general, applications or commands that modify the file allocation table (FAT) can cause unpredictable results when run under multitasking environments. The following multitasking environments are currently detected: Windows Desqview DOSSHELL version 5.0 PC-MOS Please be aware of the following conditions: DiskEdit -------- Should be run in read-only mode. Diskreet -------- The Auto Open and Quick Close features are disabled under Windows. You must use the DISKREET.EXE program to manually open and close NDISKs. Any NDISKs that were opened before starting Windows will remain open and available. FileFix ------- May cause problems when unzapping a dBASE file. Erase Protect ------------- As a general rule, Erase Protect should be turned on BEFORE loading Windows. For Advanced Users: Drives can be manipulated independently from within separate instances of COMMAND.COM or NDOS.COM. Norton Control Center (NCC) --------------------------- Under Windows, only affects the current instance of COMMAND.COM or NDOS.COM. Norton Change Directory (NCD) ----------------------------- Only affects the current instance of COMMAND.COM or NDOS.COM System Information ------------------ The CPU Speed Benchmark will not reflect the true speed of the computer. Also, Windows 3.0 will not allow the XMS reporting function of System Information to operate properly, and this function is automatically disabled as a result when running under Windows 3.0. Image ----- Should be run before loading Windows or DESQview. Special Network Notes ========================================================= The Norton Utilities Version 6.0 can be installed on a network server. In order to use them effectively in a networking environment, we recommend the following: NU Environment Settings ----------------------- The Norton Utilities saves configuration information in initialization files (*.INI). Since each user on a network will likely have a unique hardware configuration, the NU environment variable must point to a directory on the user's local hard disk. For example, typing: SET NU=C:\ will instruct the Norton Utilities to find information about the user's computer in the root directory of his C: drive. You should place this statement the AUTOEXEC.BAT file. Erase Protect ------------- The first time Erase Protect is run on a network drive, it will create an invisible subdirectory off the root directory. This directory will be called TRASHCAN. All users will need rights to this directory in order for Erase Protect to work correctly. We recommend that the supervisor run Erase Protect first, then modify the directory attributes so all users have ALL RIGHTS, except SEARCH. Note: Under Novell Netware 386, user's without SEARCH rights to the TRASHCAN will not be able to recover files using UnErase. Erase Protect must be loaded AFTER the network driver (e.g. IPX) and shell (e.g. NET3). Loading Erase Protect before the network software will prevent it from protecting network drives. NCD --- NCD saves a copy of the directory tree on the drive, so that it doesn't have to scan the drive every time it is run. On a network drive, it will try to save the directory tree in a subdirectory called NCDTREE. On non-network drives, the directory tree is saved in the root directory, but most networks don't give users any rights to the root directory. For this reason, in order to use NCD on a network drive, the supervisor should create a directory in the root directory called NCDTREE and give all users ALL RIGHTS to this directory. --------------------------------------------------------------------
