If you are using MS-DOS 6.0 or 6.2 with a Novell network, you may
receive the following error message or your system may stop responding
Because the Novell NET.COM file requires that you use SETVER (set for
MS-DOS version 5.0 by default), the OS_VERSION environment variable is
set to the current version as follows:
Many Novell system login scripts map the COMSPEC environment variable
to the OS_VERSION variable. (This is not an MS-DOS environment
variable.) Under this configuration, when MS-DOS needs to find the
transient portion of COMMAND.COM, it looks in the V5.00 directory on
the network and may lock the computer or generate the error message
To temporarily work around this problem, do the following:
• Create a directory for the MS-DOS files called V4.60 on the
• Copy the MS-DOS 6.0 files to the V4.60 directory.
• Modify the SETVER.EXE table by typing the following at the MS-DOS
• Restart your computer by pressing CTRL+ALT+DEL.
NOTE: This procedure requires that you use a directory name with a
version number earlier than 5.0 (4.40, 4.50, and so forth). The actual
directory name doesn't matter since NETX depends on the major version
The new Novell shell (version 3.32) is compatible with MS-DOS 6.0. The
new shell is available for download from the NOVFILES area on
CompuServe in the file DOSUP7.EXE.
NOTE: To make this version work correctly, you must remove the SETVER
entry for NETX.EXE, BNETX.EXE, EMSNETX.EXE, or XMSNETX.EXE. For
example, type setver netx.exe /d at
the MS-DOS command prompt and then press ENTER.
If you are using MS-DOS 6.2 with the Novell 3.32 shell, you still need
to use a directory called V6.00 if you want to use %OS_VERSION. This
information may change when Novell releases an MS-DOS 6.2-compatible
version of its shell.
