I just got a Shuttle ST20G5. After installing my two hard drives, vid card, cpu and ram I tried installing XP. In the setup screen after it asks me to install XP or not I click yes. After that setup says it cannot see any hard drives and asks to reboot itself. Why would this happen? The BIOS see's both just fine. At first I thought it was because both hard drives are Serial ATA and the optical is IDE setup as master. I set it to slave to no avail. Anyone have suggetions?
