Novell Login Drive Not Available After Installing DoubleSpace (97565)
The information in this article applies to:
• Microsoft MS-DOS operating system 6.0
• Microsoft MS-DOS operating system 6.2
• Microsoft MS-DOS operating system 6.22

This information applies to both Microsoft DoubleSpace and Microsoft
DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands
After you install Microsoft DoubleSpace, the drive letter F (normally
used by Novell NetWare) may be in use.
To work around this problem, you can either use a different drive
letter for your login drive, or adjust DoubleSpace so that it uses a
different drive letter for its host drive.
You can avoid this problem if you make sure your NetWare software is
loaded before you run DoubleSpace to compress your drives.
If your usual NetWare drive letter is not available, one of the
following should correct the problem:
• If your CONFIG.SYS file has a DEVICEHIGH=C:\DOS\DBLSPACE.SYS
command, make sure it is placed before any RAMDrive statements.
Changing the order of the RAMDrive and DBLSPACE.SYS lines in the
CONFIG.SYS file changes the "Last drive reserved for DoubleSpace's
use:" setting in the DBLSPACE.INI file, freeing up an additional
• Edit the DBLSPACE.INI file to manually change the host drive
letter. To do this:
• If you use Microsoft Windows and have a permanent swap file (PSF),
run Windows, note the current size of your PSF and change your PSF
to None. (You will undo this change later in this procedure.)
• Change to the host drive (for example H).
• Use the ATTRIB command to change the file attribute on the
DBLSPACE.INI file. For example:
attrib h:\dblspace.ini -s -h -r
• Edit the DBLSPACE.INI file with a text editor, such as MS-DOS
• Change the LastDrive setting to the letter you want to be the host
drive. For example, if you have only one hard disk drive (C), you
should use D for the host drive so that F will be available for your
Novell login drive. To do this, change the FirstDrive and LastDrive
statements to read as follows:
• Change the first parameter in the ActivateDrive line to the same
letter you used in step 4.
WARNING: Do not change the second parameter (represented by
"xx") in the following example:
Before change: ActivateDrive=H,xx
After change: ActivateDrive=D,xx
WARNING: If you use a drive letter that is used by a physical
device (such as drive A), for the N value, the system may stop
responding (hang) or continually reboot when you restart it.
• Save your changes and quit the text editor.
• Reset the system, hidden, and read-only attributes on the
DBLSPACE.INI file. For example:
attrib h:\dblspace.ini +s +h +r
• Restart your computer (press CTRL+ALT+DEL).
• If you removed your PSF in step 1, run Microsoft Windows and
re-create the PSF on your host drive. Do not attempt to create
the PSF on your DoubleSpace-compressed drive. You may receive
the following message if you re-create your PSF at its
You can ignore this error message; it is likely incorrect. As long
as the PSF is not larger than four times your physical memory,
Windows can use a swap file that is larger than the recommended
