SCSI Interface Board Not Properly Seated
If the SCSI interface board is not fully seated into the computer’s expansion
slot, the device driver software will not recognize it. Inspect the interface
board where it seats into the connector on your computer’s motherboard.
There should not be more than a small gap between the interface board and
the connector.
Symptom
• Incorrect DOS version
Possible Causes and Solutions
Conflict Between MS-DOS 5.0 and Microsoft’s CD-ROM Extensions Version
2.2 (or Lower)
MS-DOS 5.0 users should use Microsoft’s CD-ROM Extensions (file name
MSCDEX.EXE) Version 2.25. If you do not have either of these versions and
plan to use DOS 5.0 with MSCDEX.EXE Ver 2.2 (or lower), you can resolve this
conflict by doing the following
1) Type the following line into your CONFIG.SYS file:
DEVICE=C:\DOS\SETVER.EXE
2) Switch to the DOS prompt.
3) Type the following:
SETVER MSCDEX.EXE 4.01
Then press the Enter key.
4) Reboot your computer.
Conflict Between MS-DOS 6.0 and Microsoft’s CD-ROM Extensions (file
name: MSCDEX.EXE) Version 2.21 (or Lower)
MSCDEX.EXE Ver. 2.22 (or higher, preferably ver. 2.25) must be used with
DOS 6.0. Use of an earlier version will result in an Incorrect DOS Version
message. A copy of MSCDEX.EXE ver. 2.25, is included with DOS 6.0. You can
find this file in your C:\DOS directory.
If you previously had loaded MSCDEX.EXE ver. 2.21 (or lower), your computer
might still be recognizing this lower version rather than 2.22 (or higher).
