I agree with tagej. Do you have your BIOS settings for that IDE channel and device set to "AUTO"? If you have it set to "NONE" then of course it won't show up during boot.
There were BIOS limitations (due to bugs) in AWARD BIOSes around that timeframe, issues with both 32GB and 60-something GB HDs. (And of course the 128GB limit from lack of 48-bit LBA support.)
In both cases that I am aware of, though, the BIOS will still display the drive model/mfg during bootup (if set to "AUTO"), but then the BIOS will either proceed to detect the drive with the wrong size, or will hang during boot.
For it to just silently ignore it completely... something's wrong there.
I would recommend downloading the mfg's diagnostic DOS boot-disk for that drive brand, and run it. Those bypass the BIOS and try to talk to the drive directly via the IDE ports, and that will tell you if the drive is working and communicates properly with the host (computer).
