Question : Problem: Primary Hard Drive not detected in BIOS

I just purchased a K6-166 and a Gigabyte XT motherboard.  After installing I went into the BIOS and tried to Auto detect my 2 hard drives.  The Primary master (Western Digital 1.2Gb) could not be detected, but my Secondary master (Maxtor 3.5Gb) could.  I tried 3 different cables, 2 different power sources, to no avail.
 I will try manually setting configuration tonight, and swapping IDE #1 & #2 cables on the motherbooard.  Any other suggestions??
PLEASE reply to: [email protected] (NOT [email protected]) Thanks!

Answer : Problem: Primary Hard Drive not detected in BIOS

Try installing the drives as master one at a time. If both
drive are detected  and working when they are connected by
themselves, you might not be able to install the two IDE hard
drives together. This was a  problem with the IDE interface
when it first came out; hard drives from two manufactures may
not be able to co-exist. This problem should have been fixed
on the newer drives.
