Ok. As people have said, there is no way to set master/slave configurations with the jumpers. SATA doesn't use jumpers.
Secondly, my BIOS does not have the option of setting which drive to boot from first. Not an SATA drive anyway. It will give me the choice of: a:, c:, CD-ROM, SCSI, and I think that is all.
So here is the weird part. I flashed the BIOS to make sure I had the latest version, re-installed the SATA drivers just to be certain. Everything started working fine so I figured...I maust have fixed the problem. Well today, in the middle of doing absolutely nothing, all of a sudden my computer locks up. I reset it, and when it boots up (I have already reset it several times since both of my drives have been working) it says the same thing all over again. The BIOS does not be installed. Why is it switching the boot drive arbitrarily to the other drive in the middle of day without any reason? It just dosen't make sense. Oh, and I have the drive that I want as the main drive on Channel 0, and the other smaller drive on Channel 1, so the way I see it, it should always boot from the bigger drive on channel 0. But that obviously isn't the case. Any suggestions?
