- TITLE :DoubleSpace Estimated & Actual Compression Ratios
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- This article discusses common questions and issues with DoubleSpace
- actual compression ratio (ACR) and estimated compression ratio (ECR).
- The following three subjects are covered:
-
- - Actual Compression Ratio
- - Estimated Compression Ratio
- - Viewing and Changing the Compression Ratio
-
- More Information:
-
- Actual Compression Ratio
- ------------------------
-
- The actual compression ratio (ACR) represents the compression ratio
- for data that already exists on a drive. The ACR varies over time
- depending on the type of files you store on you hard disk.
-
- The ACR is calculated by dividing the sum of the uncompressed data
- size by the physical space consumed after the data is compressed. For
- example, if a disk with 100 megabytes (MB) of uncompressed data is
- compressed and occupies 50 MB of disk space, the compression ratio is
- 2:1. The formula is as follows:
-
- 100MB/50MB =2.0
-
- Note: 2.0 is written as 2.0:1 (that is, 2 to 1)
-
- Estimated Compression Ratio
- ---------------------------
-
- The estimated compression ratio is a number that DoubleSpace uses to
- calculate the amount of free space on a compressed drive. Changing the
- ECR doesn't change the compression algorithm or the ACR. It simply
- changes the value that DoubleSpace uses to estimate the free disk
- space.
-
- You may need to increase the compression ratio if you are trying to
- store several new highly compressible files and you are low on disk
- space.
-
- For more information on ECR:
-
- - Run DoubleSpace, choose Change Ratio from the Drive menu, and then
- press the F1 function key.
-
- -or-
-
- - Type "help dblspace /ratio" (without the quotation marks) at the
- MS-DOS command prompt.
-
- Viewing and Changing the Compression Ratio
- ------------------------------------------
-
- To view the ACR and ECR for a drive, type "dblspace" (without the
- quotation marks) at the MS-DOS command prompt, select the drive you
- are interested in, and then press the ENTER key.
-
- To view the ACR for a file or directory, use the DIR /C or DIR /CH
- command. For example, to see the ACR for COMMAND.COM, type the
- following at the MS-DOS command prompt:
-
- dir c:\command.com /ch
-
- To view the ACR for the DOS directory, type the following at the
- MS-DOS command prompt:
-
- dir \dos /ch
-
- Note: DIR /C reports the ACR of the compressed data based on an
- 8-kilobyte (K) cluster size. DIR /CH reports the ACR based on the
- compressed data based on the host drive cluster size. Use this number
- when you compare the ACR and ECR.
-
- To set the ECR to the ACR value, type "dblspace /ratio" (without the
- quotation marks) at the MS-DOS command prompt.
-
- To set the ECR to a specific value, type the following at the MS-DOS
- command prompt:
-
- dblspace /ratio=n.n
-
- where "n.n" is the ECR value.

- TITLE :Error in MS-DOS Help Example for the MENUCOLOR Command
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- If you are using an MS-DOS 6.0 multiple-configuration menu and you set
- the MENUCOLOR command in the CONFIG.SYS file to match the example
- shown in MS-DOS Help, the menu color does not display.
-
- More Information:
-
- The example in MS-DOS Help shows a space after the comma, which causes
- MS-DOS to stop reading the MENUCOLOR command when the CONFIG.SYS file
- is processed. As a result, the menu color is not displayed.
-
- To work around this problem remove the space after the comma.

- TITLE :DoubleSpace Doesn't Mount After Installing RAMDrive
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- If you use DoubleSpace with a removable hard drive (such as Syquest,
- Bernoulli, or Quatam Passport XL) and later install RAMDrive,
- DoubleSpace may refuse to mount its compressed drive(s). This problem
- only occurs if the RAMDrive DEVICE command in the CONFIG.SYS file
- precedes the removable hard drive DEVICE command line. Since RAMDrive
- may inadvertently use the drive letter of the removable drive,
- DoubleSpace may not find the compressed volume on the expected drive.
- The same behavior may occur if you remove RAMDrive after compressing
- your removable hard drive. (The drive letters shift and DoubleSpace
- does not mount.)
-
- If this problem was caused by installing RAMDrive, you can simply move
- the RAMDrive DEVICE command past the removable drive's DEVICE command
- in the CONFIG.SYS file. The advantage of this workaround is that the
- drive letter assignments stay the same.
-
- If this problem occurs after removing RAMDrive, run DBLSPACE. From the
- Drive menu, choose Mount. DoubleSpace scans all your drives for
- compressed volumes and reassigns drive letters appropriately. This
- workaround may cause problems for programs configured to specific
- drive letters.

- TITLE :Manifest Shows EMS Memory with NOEMS Switch
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- Quarterdeck's Manifest program indicates that EMS memory exists, even
- if EMM386.EXE is loaded with the NOEMS switch. If you add the NOVCPI
- switch to the EMM386.EXE line in the CONFIG.SYS file, Manifest no
- longer shows any EMS memory.
-
- More Information:
-
- EMM386.EXE version 4.45, which ships with MS-DOS 6.0 is a Virtual
- Control Program Interface (VCPI) provider even when the NOEMS switch
- is specified. With VCPI support enabled, EMM386.EXE supplies an upper
- memory frame buffer for the VCPI applications to use. When an
- application checks for EMS memory, it may see this buffer and believe
- it to be an EMS page frame, thus reporting that EMS memory is
- available when it is not. When the NOVCPI switch is added, it disables
- this upper memory buffer, thus disabling what the application is
- seeing as EMS.
-
- Maintaining VCPI server functionality with the NOEMS switch specified
- is a new feature in MS-DOS 6.0.
-
- It should be noted that VCPI support can exist without a page frame.
- For example, EMM386 in MS-DOS 5.0 (version 4.44) provided VCPI support
- by using the "frame=0" switch. In MS-DOS 6.0 we can now achieve the
- same result using both the NOEMS switch and the NOVCPI switch
- together.
-
- Manifest is manufactured by Quarterdeck Office Systems, a vendor
- independent of Microsoft; we make no warranty, implied or otherwise,
- regarding this product's performance or reliability.

-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- If DBLSPACE /RATIO or other DoubleSpace commands cause the system to
- restart, load DBLSPACE.SYS before your network drivers in the
- CONFIG.SYS file.
-
- More Information:
-
- Setup installs DBLSPACE.SYS before any network drivers, so this
- problem should not occur unless you have moved the DBLSPACE.SYS driver

- TITLE :Err Msg: SYS Is Unable to Operate on Target Drive
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- If you try to run SYS.COM on a drive that has been compressed with the
- DoubleSpace, you may receive the following error message:
-
- SYS is unable to operate on target drive
-
- To work around this problem, you must manually unmount the compressed
- drive before you run the SYS command to make drive C a bootable drive.
-
- More Information:
-
- This error usually occurs when an attempt is made to run SYS.COM on a
- hard disk drive that has been compressed with DoubleSpace and has
- failed because of corrupted MS-DOS files. DoubleSpace performs "drive
- swapping," giving the physical drive a drive letter other than C
- (typically the fifth letter after the system's last block device) and
- designating the compressed volume file as drive C. Even if you boot
- from a floppy disk, it is possible that DoubleSpace will mount the
- compressed drive and perform the drive swap. Because we cannot run
- SYS.COM on a DBLSPACE drive, SYS.COM generates the error message.

- TITLE :Difference Between the DIR /C and DIR /CH Commands
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- The DIR command has two switches that you can use to display
- compression ratio information, /C and /CH. /C displays the compression
- ratio of a file assuming that it resides on a drive using 8-kilobyte
- (K) clusters. /CH uses the cluster size of the host partition. In most
- cases, there is no difference between the output of these switches
- unless your DoubleSpace host partition uses a cluster size other than
- 8 kilobytes. For example, if you have a file on a drive using 4K
- clusters, the compression ratio displayed generated from DIR /C would
- be 1.5; DIR /CH would generate a compression ratio of 2.0.

- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- Microsoft CD-ROM Extensions (MSCDEX.EXE) version 2.22 for MS-DOS is
- included in MS-DOS 6 Upgrade and MS-DOS 6.0 plus Enhanced Tools.
- MSCDEX.EXE version 2.22 includes code to recognize MS-DOS 6.0 and make
- it easier to load MSCDEX.EXE into upper memory blocks (UMBs).
- (MSCDEX.EXE 2.22 has a smaller initialization size than earlier
- versions, making it easier to fit in smaller UMBs.)
-
- MSCDEX.EXE is included with MS-DOS 6.0 so that you do not need to
- obtain additional software to continue using your CD-ROM drive after
- you upgrade to MS-DOS 6.0.

- TITLE :Using DoubleSpace to Compress a Bootable HardCard
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- You should not use DoubleSpace to compress your boot drive if that
- drive requires a device driver in the CONFIG.SYS file. Because the
- DoubleSpace driver (DBLSPACE.BIN) is loaded with IO.SYS before the
- CONFIG.SYS file is processed, Microsoft does not support this
- configuration. If you want to use DoubleSpace on such a drive, you
- must mount the drive after loading the device drivers in the
- CONFIG.SYS file.
-
- For example, if drive C is a Plus Hardcard and you compress that
- drive, DoubleSpace cannot automatically mount the drive. You can
- either mount the drive from the MS-DOS command prompt or from the
- AUTEOXEC.BAT file.
-
- Note: DoubleSpace does not support compression of removable hard disk
- drives that require a device driver to write to the drive. This is
- because DoubleSpace must mount the drive before the CONFIG.SYS file is
- processed, and the mounting process rewrites the BitFAT structure in
- the compressed volume file (CVF).
-
- More Information:
-
- You can manually mount the DoubleSpace drive from the command line by
- using the DBLSPACE /MO command. If you want to mount the compressed
- drive from the AUTOEXEC.BAT file, you must copy the CONFIG.SYS and
- AUTOEXEC.BAT files to the host drive, copy the device drivers called
- from those files, and then add a line to the AUTOEXEC.BAT file to
- mount the compressed drive. To do this, follow the procedure outlined
- below.
-
- Note: This procedure does not work if your drive does not meet the
- following conditions:
-
- - It is bootable (that is, accessed by the BIOS during the startup
- process).
-
- - It is a system disk. (If it is not, use the SYS command to transfer
- the MS-DOS system files.)
-
- To automatically mount the compressed drive:
-
- 1. Compress the boot drive with DoubleSpace. For example, to compress
- drive C, type the following at the MS-DOS command prompt:
-
- DBLSPACE /COMPRESS C:
-
- 2. Ensure the following files are in the root directory of the host
- drive (the drive containing the compressed volume file [CVF]):
-
- IO.SYS
- MSDOS.SYS
- COMMAND.COM
- DBLSPACE.BIN
- DBLSPACE.000
-
- To determine which drive is the host drive, type "DBLSPACE /LIST"
- (without the quotation marks) at the MS-DOS command prompt.
-
- Since the files listed above have read-only, hidden, and system
- file attributes set, use the /A parameter to see the files. To do
- this, type DIR /A at the MS-DOS command prompt.
-
- 3. Copy the following three files to the root of the host drive:
- DBLSPACE.EXE, CONFIG.SYS, and AUTOEXEC.BAT.
-
- For example, if H is your host drive, you would use the following
- three commands to copy these files:
-
- copy c:\dos\dblspace.exe h:\
- copy c:\config.sys h:\
- copy c:\autoexec.bat h:\
-
- 4. Copy any files called from the CONFIG.SYS file to the host drive.
- For example, if the command DEVICE=C:\DOS\HIMEM.SYS is in your
- CONFIG.SYS file, copy HIMEM.SYS to the host drive with the
- following command:
-
- copy c:\dos\himem.sys h:\
-
- 5. Edit the CONFIG.SYS file on the host drive to reflect the new
- location of the device drivers. Given the above HIMEM.SYS example,
- change the CONFIG.SYS file on the host drive (H) to read as follows:
-
- device=c:\himem.sys
-
- 6. Add the following line to the AUTOEXEC.BAT file on the host drive:
-
- DBLSPACE /MO
-
- 7. Any other programs or executable files called from the AUTOEXEC.BAT
- file should be located on the host drive. If they are not, you need
- to edit the AUTEXEC.BAT file to reference the correct drive letter.
- The host and boot drive letters swap when the DBLSPACE /MO line is
- run from the AUTEOXEC.BAT file.

- TITLE :Differences Between DOSSHELL.INI in MS-DOS Versions 5 and 6
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- This article discusses the differences between the DOSSHELL.INI file
- in MS-DOS versions 5.0 and 6.0.
-
- More Information:
-
- The DOSSHELL.INI file in MS-DOS 6.0 does not contain references to the
- MS-DOS 5.0 BACKUP and RESTORE commands.
-
- Since Setup doesn't update a existing DOSSHELL.INI file, the existing
- references to Backup Fixed Disk and Restore Fixed Disk are not
- updated. BACKUP.EXE is copied to the OLD_DOS directory so that the
- Backup Fixed Disk option no longer works. You can either copy the
- MS-DOS 5.0 BACKUP command (BACKUP.COM) to the DOS directory or modify
- the Backup Fixed Disk properties to reference the new backup program,
- Microsoft Backup (MSBACKUP.EXE).
-
- If you don't have an existing DOSSHELL.INI file, Setup creates a new
- one with the following default items:
-
- Main Menu
- ---------
-
- Command Prompt
- Editor
- MS-DOS QBasic
-
- Disk Utilities Menu
- -------------------
-
- MS Anti-Virus
- MS Backup
- Quick Format
- Format
- Undelete
-
- Setup leaves the RESTORE command (RESTORE.EXE) from MS-DOS 5.0 in the
- DOS directory even though it does not appear as an item in MS-DOS 6
- Shell. The BACKUP command (BACKUP.EXE) from MS-DOS 5.0 is available on
- the supplemental disk or in the OLD_DOS directory as described above.
-
- To replace your existing DOSSHELL.INI file, you can expand the
- appropriate .IN_ file from the original MS-DOS 6 Upgrade disks. For
- example, if you have an EGA or VGA video display card, expand EGA.IN_
- from the MS-DOS 6 Upgrade disks (Disk 2 of the 1.2-megabyte (MB) set
- or Disk 1 of the 1.44-MB set). For example, if you insert the Setup
- disk in drive A, you would type the following command:
-
- expand a:ega.in_ c:\dos\ega.ini
-
- If the new utilities made available by the MS-DOS 6.0 DOSSHELL.INI
- file are not installed, you must install them using the SETUP command
- with the /E parameter.

- TITLE :Situations in Which Defragmenter Cannot Run
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- Microsoft Defragmenter operates on the MS-DOS logical drive level
- only. Third-party partitioning utilities that modify or translate disk
- geometry (such as Disk Manager and SpeedStor) operate beneath the
- MS-DOS file system and are therefore transparent to Defragmenter.
-
- Defragmenter cannot share access to a drive with other tasks;
- therefore, you cannot run Defragmenter if Windows or DESQview is
- running.
-
- More Information:
-
- Defragmenter does not work in the following situations:
-
- Situation Reason
- ---------- ------
-
- Network Drive Network software usually does not allow full
- single-tasking access to the entire drive,
- including the file tables. Often network drives
- (such as Novell NetWare) use another file system.
-
- CHKDSK Errors Errors in the drive organization can cause
- unpredictable results from Defragmenter.
- Defragmenter identifies most CHKDSK errors while
- reading the drive organization and then refuses
- to run until you correct them.
-
- Windows Defragmenter cannot operate properly in a
- multitasking or task-switching situation;
- therefore, it detects Windows in real, standard,
- and 386 enhanced modes and does not run.
-
- Task Swapper Defragmenter cannot operate properly in a
- task-switching situation; therefore, it detects
- the MS-DOS Shell task swapper and does not run.
-
- Interlnk Drives Interlnk is not designed to support defragmentation
- and other low-level utilities. Specifically, it does
- not implement interrupts 25 and 26.
-
- Fastopen The Fastopen program tracks which files are located
- in which clusters on your disk. Defragmenter
- rearranges data on a cluster level, which confuses
- Fastopen.
-
- JOIN JOIN does not allow normal access to a drive.
-
- SUBST SUBST drives do not have their own file tables or
- directories to optimize.
-
- The products included here are manufactured by vendors independent of
- Microsoft; we make no warranty, implied or otherwise, regarding these
- products' performance or reliability.

-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- If you are running FTP Software's PC/TCP network software and
- Microsoft Windows in 386 enhanced mode, your SYSTEM.INI file may
- contain the line DEVICE=C:\PCTCP\VPCTCP.386 in the [386Enh] section.
- If it does, Windows may stop responding (hang) at the logo screen
- after you have compressed a drive with DoubleSpace.
-
- More Information:
-
- The system hangs if the line DEVICE=C:\DOS\DBLSPACE.SYS /MOVE is not
- present in your CONFIG.SYS file before any of the drivers that load
- the network. To correct this problem, add or move the line
- C:\DOS\DBLSPACE.SYS /MOVE before the first line that loads the network
- software. In most cases, the first line that starts the network is
- something similar to C:\PCTCP\PROTMAN.SYS /i:C:\PCTCP.

- TITLE :Regions Scanned by the EMM386.EXE HIGHSCAN Switch
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- The HIGHSCAN switch included in EMM386.EXE version 4.45 allows
- EMM386.EXE to map expanded memory pages or upper memory blocks (UMBs)
- over portions of the upper memory area (UMA) used by system read-only
- memory (ROM).
-
- Choosing "Yes" in response to the MemMaker prompt "Scan the upper
- memory area aggressively?" causes MemMaker to add HIGHSCAN to the
- EMM386.EXE device= line.
-
- More Information:
-
- If you use the HIGHSCAN switch on the DEVICE=C:\DOS\EMM386.EXE line in
- the CONFIG.SYS file, EMM386.EXE examines the system ROM area starting
- at memory location F000:0000. If EMM386.EXE determines that ROM is
- duplicated between F000h-F7FFh and F800h-FFFFh, EMM386.EXE uses the
- F000h-F7FFh region for expanded memory page mapping or UMB memory.
- (This adds up to 32 kilobytes to the UMA.
-
- On Micro Channel (MCA) systems with ROM BASIC (for example, IBM PS/2
- systems), the HIGHSCAN switch allows EMM386.EXE to map expanded memory
- or UMB memory over the ROM BASIC code in the system ROM. Typically
- this is the region from F600 to FDFF.
-
- Note: On some systems, EMM386.EXE uses the ROM area and the system
- does not operate correctly. The symptoms of this condition vary. For
- example, the system may stop responding (hang) or appear to operate
- normally until you use a floppy disk drive. Because of these potential
- problems, HIGHSCAN is not used by default.

- TITLE :Setup Leaves Windows .INI Files in Root of the Novell Server
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- If you run MS-DOS 6 Setup when you are logged onto a Novell server,
- Setup may leave MS-DOS initialization (.INI) files in the root
- directory. This problem occurs when all the following conditions are
- exist:
-
- - You are logged on as a supervisor or a user with full access
- privileges to the root of the file server.
-
- - You are using a shared installation of Windows (installed with the
- SETUP /N command).
-
- - Your Windows initialization files are in a user directory that is
- being accessed with a search drive.
-
- - You have installed the Windows-based optional utilities.
-
- If these conditions exist, MS-DOS 6 Setup leaves your initialization
- files in the root of the Novell file server.
-
- The following initialization files are left in the root of the Novell
- server:
-
- PROTMAN.INI
- SYSTEM.INI
- WINFILE.INI
-
- Setup also leaves the backup (.BAK) files for those files in the root
- of the Novell file server.
-
- Workaround
- ----------
-
- Use one of the following techniques to correct this situation:
-
- - If this is the only installation of MS-DOS 6 you plan to perform
- when you are logged in as supervisor, you can simply move these
- six files back to the user directory.
-
- - If you plan to do multiple installations of MS-DOS 6 when you are
- logged in as supervisor, temporarily override the search drive before
- beginning the MS-DOS 6 Setup on each subsequent computer. For example,
- if your Windows initialization files are accessed on Search drive
- W:\USER\JOEB. Before beginning the MS-DOS 6 Setup type these two
- commands at the MS-DOS command prompt:
-
- map del w:
- map w:=sys:user\joeb
-
- When MS-DOS 6 Setup prompts you for the location of Windows directory,
- use W:\USER\JOEB for the path.
-
- Note: If desired, you may substitute the second command above with the
- following:
-
- map root w:=sys:user\joeb
-
- When MS-DOS 6 Setup prompts you for the location of Windows, use W:\
- for the path.
-
- More Information:
-
- Do not use a search drive to specify the location of your Windows
- initialization files. A search drive represents its drive letter as
- "<drive>:." instead of "<drive>:\<pathname>." MS-DOS 6 looks at
- "<drive>:.", changes to the root of the drive, and then looks for the
- current (.) directory. This is why MS-DOS 6 writes the files to the
- root of the server.
-
- If you are logged on as a user without write access privileges to the
- root of the file server (as is generally the case with a user on a
- Novell network), the same approach as described in the second
- technique applies. If you don't have privileges in the root directory,
- the temporary initialization files (.$$$) are written to your user
- directory. No changes are been made to your original initialization
- files. You can safely delete these .$$$ files. Use the second
- technique and then restart the MS-DOS 6 Setup program.
-
- The following three .$$$ files may be left in your user directory:
-
- __SYS__.$$$
- __PGI__.$$$
- __WFI__.$$$
-
- If Setup detects that it did not need to modify one or more of the
- initialization files, you may not have all three of these in your user
- directory.
-
- Note: This information applies to both the SETUP and SETUP /E
- commands. (SETUP /E is used to install the optional components.)

- Microsoft Defragmenter reorganizes data on MS-DOS drives so that it
- can be retrieved faster.
-
- MS-DOS organizes data on the hard disk into a series of clusters
- (allocation units) and then tracks which files are using which
- clusters through directory structures and the file allocation tables
- (FATs). Neither users nor applications need to know exactly where
- specific data is located on the hard disk. When an application needs a
- file, it simply asks MS-DOS to get it.
-
- Over time, pieces of files may be spread all over the hard disk. When
- this occurs, retrieving files requires more time. Defragmenter
- reorganizes the clusters for faster access. (For example, information
- is stored at the front of the disk, and parts of files are regrouped
- together). Defragmenter uses interrupt calls 25H and 26H to move the
- information stored in one cluster to another, directly updating the
- FATs and directory structures.
-
- Defragmenter operates at nearly the same level as MS-DOS. However, it
- is still uses MS-DOS and is protected from direct interactions with
- the following:
-
- - Third-party partitioning utilities that modify or translate disk
- geometry (such as Disk Manager and SpeedStor).
-
- - DoubleSpace and third-party drive compression utilities.

- TITLE :SETVER Table Entries Are Not Maintained When Upgrading
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- If you do not install the MS-DOS 6 Upgrade in the current MS-DOS 5.0
- directory, your old SETVER entries are not maintained.
-
- More Information:
-
- When you install the MS-DOS 6 Upgrade over MS-DOS 5.0, Setup updates
- the current version table (maintained in SETVER.EXE). If you install
- MS-DOS 6 in a new directory, Setup cannot update the old version table.
-
- Workaround
- ----------
-
- To work around this problem:
-
- - Update the new SETVER.EXE file, adding the entries that your
- software requires.
-
- -or-
-
- - Uninstall MS-DOS 6.0 and reinstall the MS-DOS 6 Upgrade in the
- original MS-DOS directory.
