Kevin:
I can do the BIOS upgrade, for what it's worth. Right now, the removable drive is working as it should. What I don't understand is that in the beginning of this this, I could not get the MB to see the dive even with the drive connected directly to the MB. I used two different cables and tried nine different drives, all of which were known good. The computer would not respond to any of them. Now it's working fine. I have no idea what was going on.
