As far as a jumper on the drive, the jumper was tried either on Cable Select, Master, or removed entirely. All resulted in the drive not being able to be detected on power up. I also had a 200GB drive. For kicks, I put the Promise Technology LBA board (a board that you need when your motherboard can't recognize hard drives past 137GB) that came with the 200GB hard disk in the PC with only the 100GB connected to it. Every time I cold booted the PC, it would always come up. A different story when just plugged into the IDE channel on the board itself.
Thanks for the info on what you can't change in the BIOS by normal means.
So what do you guys think of my other question? Since I flashed the BIOS, the red DIAG light on the board is on. Doesn't really bother me as long as it doesn't hurt anything. Just wondering if there was something hardware related that could be reset to turn it off. Why would it be on after just flashing the BIOS with a different build? Is it the motherboard's way of telling the truth when you flash the BIOS like that?
