Ya, I kinda thought that was not going to turn out good as I read thru your first post.

SP2 CD should have no issues with the default AHCI or AMD ACHI drivers or any added via Slipstream (Meaning I have used TONS of Custom Built ones with MANY Extra Drivers added).

The system will scan and only install the needed ones per the system, or any you specify during F6 Driver install method.

Maybe you are burning your Disks to fast? If you do burn your own install disks you should ALWAYS burn System disks at the SLOWEST Speed possible.

Good luck, and do post back if you still have issues, or to tell us about your success.
