I have a strange issue. My IP35-E does not seem to be recognizing my sata cd drive. Its a samsung sh-203b.

The board posts, but does not show the drive. I assume it should appear here, but it does not. and i get disk boot failure if I just have the sata drive plugged in and sata cdrom set to boot first. The drive is not the problem, as it worked a few hours ago before i took everything apart for the rebuild

any ideas?
