Alan,

If you are getting that boot message and the drives don't work in Windows,
you probably have 2 separate problems.

The OEMCD001 reference is what I've seen to be the CD /D: parameter for many
OEM's.  This is used in the device driver loading in CONFIG.SYS as a name to
match with when invoking MSCDEX in AUTOEXEC.BAT or DOSSTART.BAT.  Your
problem here appears to be that the DEVICE or DEVICEHIGH command in
CONFIG.SYS has been removed or commented out.  However, this should affect
the availability of a CD ROM only in DOS mode.  To repair, either track down
your OEM's CD driver (OEMCDROM.SYS or something like that) on your system OR
make an emergency startup disk through Windows and copy the file
OAKCDROM.SYS from the diskette to your hard drive.  Then add the line
DEVICE=C:\{your path}\OAKCDROM.SYS /D:OEMCDROM to CONFIG.SYS (replacing
OAKCDROM.SYS if you found your original driver.)  If your CONFIG.SYS doesn't
have a line like LASTDRIVE=Z, add that to the end, so DOS will have enough
drive letters to work with.

Windows does not use this driver, however, but instead has built in CD
drivers.  If the drives aren't working there either, you can follow the
instructions from another poster given just recently.  From rereading, make
sure that upon startup, your BIOS identifies your CD/DVD on the secondary
IDE controller; if not, you may need to use the primary in the instructions
below.  This from Joseph Marty:

> Go back into device manager, highlight the secondaryIDE controller, then
click remove and yes to the warning.  Have your Win 98 disk handy if IBM
didn't load Win 98 into C:\windows\options\cabs on your hard drive.  Then do
a shutdown restart.  As soon as the POST screen finishes, press F5 to
startup in safe mode.  Choose safe mode (usually #3) from the choices. In
safe mode go to device manager and check the IDE controllers to make sure
you don't have multiples of them.  If you do, highlight the busmaster and
remove it, which ought to remove the controllers. If you don't, no problem.
Then close device manager, and do a shutdown/restart.  Windows should
install them correctly when it boots up.

Good luck,
