A little bit of history first:

I had (actually still have) and old Pentium 200 Micron PC. That came with a Teac CD-512E 12x CD-ROM. I added to that (a few years later) a CD Rewriter on the Secondary IDE controller set as slave. It was slow, but it worked. Then I replaced the CPU/mobo with a PIII 500, Aopen AX6BC-Pro. It was fast and still worked. A few months later... the CD burner died and has been sent off for a replacement (actually died before the warranty - woohoo!)

So - when I removed the burner and rebooted, windows (98SE) would not recognize the TEAC CD. The BIOS sees it just find and correctly identifies it during POST. I can use DOS driver with it just fine. I checked and it is still a master. Since I still had the burner I set it as a master and swapped them - worked fine. Note: 98SE was installed when the burner was installed on the original mobo.

In device manager the TEAC (no burner now) shows a red X and the Secondary IDE controller has a yellow ! and the properties say "This device is either not present. not working properly, or does not have all the drivers installed. (Code 10) I checked for driver updates - none - I checked AOPEN's web site - their site recommended changing the bus maser setting from 'Default' to 'Both IDE channels enabled' - no change. Deleted the CD from device manager. Reboot and now NO CD devices listed. Secondary IDE still has yellow ! - delete IDE controllers from device manager and they come back the same. Unplugging the CD-ROM completely and the secondary IDE has no error. I have not updated the BIOS as AOPEN does not indicate that a BIOS update will fix this problem for sure - and I am a little leary of flashing BIOS.

Am I going crazy here or is this old CD only incompatible when it is NOT the only device on the controller? Anyone seen this B4?

If it's on a IDE channel with a DMA device try moving it to the other channel. When that old rom is on the IDE channel make sure the DMA box is unchecked.

It's the only device on the channel and DMA is not ticked.
The part that seems so wierd to me is that it works if there is another device on the channel.
