Oops, I did it again. Couldn't create or make a workable ATI boot disk, let alone boot from it, until I disabled the on-mo-board Fastrack Raid controller. Everything hung until that disable. No problems since. I even verified the backup. Just don't fully re-boot until you re-activate the Bios driven Raid controller and the fasttrack controller, otherwise you may potentially lose data. Hope this helps. D.L.
