OK, the problem has been solved. I don't really understand what it was, but it seems that there was a conflict with SATA controllers, maybe because of the Promise RAID PCI card I have in there does not get along with the one that came on the mother board. In any case I went into the SATA settings and changed them from "All Enabled" to just SATA 0 enabled. The system sees my RAID as a SCSI drive even though it is SATA, but that left only the C drive as and SATA drive. I presume that by enabling only the SATA 0 controller, I was setting The C drive as the only SATA drive. What that all had to do with the wireless PCI card, I have no Idea. Thank you to all of you who tried to help me. I certainly learned a lot more about the BIOS than I did before.
