99% chance you just need to turn off AHCI mode in your BIOS, Greg.
Or do the F6 thing and install the drivers.
Greg, take a few minutes and integrate the gigabyte drivers into a custom install using nlite that I linked above. Once you do this, you won't have to mess with driver downloads because windows will have the correct drivers built in.
UPDATE: I'm watching Miami play Dallas, JLO is singing in PowerDVD 10, I'm ripping my CD's to my hard drive, using EAC, typing this, and I'm using 5% of the processor, and 18% of the RAM???
Super computers are here...
