I have a Dell GX 620 that came with a SATA HD and an IDE CD-ROM drive.
I added a hard drive as a slave on the ide chain and formatted it in XP
without any problems. I then swapped the cd-rom drive for a dvd-rom
drive and used the exact same jumper settings. Now when I boot the PC,
I get errors that drives 4 and 5 (PATA-0 and PATA-1) cannot be found.
However, if I boot into Windows XP, both drives appear under My
Computer and they both are 100% working. Does anyone have any ideas on
why bios will not read them? I'm using Phoenix ROM BIOS PLUS Version
1.10 A07. Thanks.

BIOS issues are best addressed by the motherboard manufacturer.
