I recently installed a SATA drive with a SIIG SATA controller on my A7V133 mobo and have been using the drive a few weeks for backup files. Now I want to use it as my boot drive, but Win XP Setup can't detect it. Before booting from the XP CD, I enabled SCSI in BIOS, set SCSI as second in boot sequence (after CD-ROM) and entered the SI website's latest driver when called for in Setup. The setup message is "there is no disk in this drive" and it labels the drive as "157066 MB disk 0 at Id 0 on bus 0 on si3112 (MBR)." The Asus has a RAID option, but I'm not sure whether this would be an option since the drive runs off its own card. Appreciate suggestions!
