When installing Windows on a SATA drive you first have to see if there is an ide controller on the board. The ide controller will override the SATA bt default. With a strictly SATA board there is no eide controller to run a good old 40 or 80gb drive. A floppy disk with the SATA drivers has to be made up before running the installer for Windows. When the prompt comes up for other devices you then browse the floppy to have the installer copy those off of the 3 1/2". Windows is supposed to then see the SATA drive.
(don't feel bad. I'm still waiting for a friend to get busy getting his sata hd up and going to get my loaned out ide drive back.)
