Error in CONFIG.SYS line XX
Usually caused by a missing/corrupted file or device driver, or
typing error.
Bad or missing COMMAND.COM
Any
one of the following reasons could be the cause of this message
COMMAND.COM file was deleted or renamed.
COMMAND.COM wrong version
COMMAND.COM has a damaged header.
SOLUTION:
Use a Startup floppy (must be the same version or later as the
system your trying to boot).
Type sys c: at the A:\> prompt and press enter.
Reboot
HIMEM.SYS not loaded
The
HIMEM.SYS command line in your config.sys file must appear before
any commands that start programs or device drivers that use extended
memory. If any of these other programs or devices try to load before
HIMEM.SYS is loaded you could receive this error message.
Missing or corrupt HIMEM.SYS
The
file may have been deleted from the C:\WINDOWS\COMMAND directory, or
there is a line in CONFIG.SYS calling on a different version of
HIMEM.SYS.
SCSI
The
SCSI and CD-ROM support built into Windows requires that CD-ROM
drives provide SCSI parity to function properly. For many drives,
this is a configurable option or is active by default.
The
ends of the SCSI bus must have installed. In addition to the
requirement that the last external and the last internal SCSI device
be terminated, some hardware have additional requirements for where
it must be placed in the SCSI chain.
If
Setup does not automatically detect a SCSI CD-ROM drive, try the
following:
-
Try loading real-mode drivers for the SCSI controller, the
CD-ROM driver, and Mscdex.exe, and see if the CD-ROM drive works
in MS-DOS.
-
If the drive does work in MS-DOS, in Device Manager, examine the
SCSI controller’s properties to make sure it was detected
correctly.
-
Check your physical connections.
-
Check the SCSI IDs for all devices to make sure they are unique.
A
SCSI or IDE tape drive or scanner does not show up in Device
Manager. Windows does not assign drive letters to tape drives and
scanners, because they have no drive to assign a letter to.
Therefore, they might appear as Unknown Devices in Device Manager.
After you start Windows, it asks if you have a driver for these
devices. If you have Windows drivers, click Yes, and then type the
path to where the drivers are located. To use existing real-mode
drivers, click No. Windows will continue to recognize and support
these devices although they are listed as Unknown Devices. |
