Frankly, I would not set the usb as first boot device. Here are some issues you might want to double check in trying to get this drive to work. I would set it up "properly" or the "standard setup" and see if you can get it going. Suggestions:
Give these things a try:
- In the bios, you should have the Sata set in IDE mode, do you?
- In the Bios, you should have the Sata options enabled, do you?
- When you start to load the OS, did you load the Sata drivers at the F6 prompt, you should?
- Are you certain you have the Sata hooked to the correct connection on the motherboard?
- Do you have the Bios set to boot as follows:
CDRom - 1st
Floppy - 2nd
Hard Drive - 3rd
- Do you have the Hard Drive Priority in the Boot area set with the Sata listed FIRST?
Give these a try and see what happens.
