Getting CD-ROM recognized outside of BIOS

[mainit123]

I am running Windows 98SE on a clone PC. On the Primary
Controller, I have a Seagate 8 GB drive that is my C:
drive (master) and a Matsushita CD-ROM (not a burner,
just reads CD) for the slave on that controller. The
jumper pin on the CD is set to Slave.
On the secondary controller, I have a Maxtor 20 GB
drive (master) and no slave.
On boot, the AMI BIOS sees these three devices just fine.
Windows98SE sees the two hard disks as C: and D: but
never can recognize the CD-ROM. I have a yellow
exclamation mark on each controller in Device Manager
and NO recognition of the CD-ROM in any program
(Windows Explorer or Device Manager).

How can the BIOS recognize this CD-ROM and yet it
doesn't show in Windows? I can get at the data on
the C: and D: drives just fine. This whole setup
was working fine until I had to change ribbon cables.
I made no other changes except to swap the existing
ribbon cable with a different one to clean up some
clutter in the chassis.
I can boot from a Windows98SE boot disk and the CD
DOES get recognized to where I can copy data from
a CD in that drive to one of the hard drives so I
know the CD is physically working fine.

I am asking why I cannot see this CD ROM when in
Windows and how to remove the yellow exclamation
marks from both controllers in Device Manager?

Thanks.
Joel

Usually a matter of the chip drivers getting clobbered or not being installed correctly.
This is most prevalent on intel or VIA chipsets.
Your BIOS has minimal to read all, but the SE loads replacement stuff.
Your M/B should have come with floppy or CD with drivers. If so, reload them. Or get them off the web.
