I’m attempting to restore an old Windows 98 PC from 2002. The CMOS battery was obviously dead so I replaced it. Everything works, except for the CD ROM drive. Every time I boot the computer, I get the error:
Pri Slave Drive - ATAPI Incompatible
Press F1 to Resume
If I press F1 and continue to Windows 98, the drive does not show up. However, there is an interesting A drive titled "Removable Disk (A:). I don't have any drives in the computer other than the hard drive and CD ROM, so that is strange to me and perhaps is related.
In the BIOS (AMIBIOS Release 09/12/2002 S), all drives are set to be auto detected. However, if I press enter on the second drive (AKA what should be the CD ROM) which is supposed to detect the type of drive, it sets the type of drive to ARMD (ATAPI Removable Media Device). This is similar to what Windows detects. I have already attempted to set the BIOS to its defaults.
As for physical jumpers, the drive is on the same cable as the hard drive and the jumper is set to slave. This should work as it was what was in the computer originally. I would assume that the drive worked at some point as there was a disk in it when I got the computer.
How can I get the CD ROM drive to be detected by the BIOS and Windows? Do I have a hardware fault?

Moab, in a comment, suggested that a fix could be setting the jumpers on the CDROM and HDD to "cable select" as the motherboard may not work with the master-slave configuration. This fixed the problem, although the CDROM is now master and the HDD is slave. However, this doesn't seem to be causing any problems. The computer boots without the incompatibility error.
