MS-dos compatibility mode & lost CD drive

[Barrie]

My hard drive & partitions all read as MSDOS
compatibility mode, and the CDRW/DVD drive is not shown
in Windows 98SE, so I cannot access it. (It was the H:
drive).
This happened after trying to install a USB mobile disk
driver. I have uninstalled the driver to see if that
would resolve the problem, but this did not work.
I have also checked the internal cables - there are no
loose wires.
Any help would be greatly appeciated. Thank you.

Thank you. I have already looked at some of these, but
will try the other articles when I get home from work
this evening.
Regards, Barrie.

PS The driver I tried to install was for a Twinmos mobile
disk(not sure if that is relevant). The CD is a Lite-on
CDRW/DVD combi.

Turned out it was the VIA busmaster chipset. Everything
now working, after downloading new driver from Viatech.
Many thanks for your help. Regards, Barrie
