Please list your system specs, what you were trying to do and what you have done so far t fix the problem. We can't help without the right info...My initial thought is that you shouldn't have to do a BIOS flash to get the system to recognize a HDD...

I had the same problem, Windows XP wouldn't install cause it couldn't find the WD Raptor SATA drive at all. I tried installing the drivers, etc. and nothing worked. Finally, I used my friends version of Windows XP SP1 and it installed perfectly.
Hope this helps.
