CD detected by bios, disappeared in win98

[bruntoj]

A few days ago my system was fine (win98, Dragon+ AMD1800+) and last night I found that my CDROM drive had disappeared from Win98. It is detected correctly at bootup by the bios, but in Win98 its not there (Explore and Device Mgr).

The only thing I did recently was attach some USB devices. I've unplugged my USB hub, cold-booted, tried detecting new hardware (nothing).

The CD is primary in IDE1, and I have a Western Digital HD as primary in IDE2. (My boot drive is a SCSI HD).

The only reference I can find to disappearing CD drives makes mention of VIA4-in-1 drivers, and I haven't started messing with Bios and MB drivers yet, because the CD is detected at bootup...

I don't know if this applies to the current mobo's out there, but I ran into this problem a number of times a few years back when I was the official "computer guy" for my dorm.

In your BIOS, do you have the system set to auto-detect or CD-ROM on that channel? Try turning that off (selecting none) and booting. That usually did the trick. But again, I don't know if that trick/problem still applies.

lazily lifted off another webpage:

Symptoms:
- CDROM drive disappears
- In device manager, both "Primary IDE controller" and "Secondary IDE controller" appear with a yellow exclamation mark
- In device manager under "performance", all HD's appear in compatibility mode.

Solution:
Click Start, then Run... , and type regedit
Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\IOS
You should see a value named "NoIDE". Delete it, close regedit and reboot!

can you boot of a cd?

Slikkster, there's no "NoIDE" value or key in that section of my registry, and searching the registry for it comes up zip too.
I'll reboot and tool around with the bios and see if anything matches Praetor's info.
Thanks for the suggestions.

EDIT:
Still no luck. Was set as "auto" in bios so I set it to off and restarted. Then restarted again and changed bios back to "Auto" and booted. Bios identifies the drive (Hewlett P.....) but still nothing in Windohs. I was hoping it would detect new hardware or something.

Device Manager has no problems, and I can see Primary and Secondary IDE controllers, as well as a "VIA Bus Master PCI IDE Controller".

FIXED.
swapped the CD and HD around between IDE1&2 (just swapped the connectors on the MB)
(and they were seated properly to begin with!)
