cd rom drive disappears when I install a new hard drive ???

Okay, I have a question for the experts here.

I have a dell dimension XPS D266 computer (pentium II computer, I believe).
Anyway, this computer is running windows 98. When the computer was first
setup, it had a C drive (8 gigs in size) and an NEC cd rom drive (setup as
drive D).

I recently added a second hard drive to the system (a fujistu hard drive, 20
gigs in size) and that drive has become drive D. Now when the system starts,
the cd rom drive does not appear in my computer icon, but when I run any
applications or insert a cd, I can run programs from the cd rom drive and the
computer recognizes the cd drom drive as drive E.

When I removed the new fujitsu hard drive and set the computer back to just
a c drive and the cd rom drive, everything was okay, except for the fact that
I had losted the cd rom drive for awhile until I removed the cd rom drive and
let windows 98 detect the cd rom drive again.


I reinstalled the fujitsu hard drive again, and the bios recognizes that
there are two hard drives and a cd rom drive, but again the my computer
windows/Icon shows that there is no cd rom drive, just a c drive and a d
drive. When you right click on my computer icon and check the hardware
window, the cd rom drive is displayed there along with the two hard drives.

I tried to remove and re-detect the cd rom drive in the hardware section of
my computer but no cd rom drive was added to the my computer window. Its as
if the computer will not let the user see the cd rom drive, but its there and
you can run applications off the cd rom drive. You can reference the cd rom
drive as drive E.

Does anyone know what has happened and can anyone explain ow I can fix this
problem?
