SCSI drive won't boot

[Nabis]

This is my first foray with both a scsi drive and a sata drive both on the same mobo, and I can't get my scsi drive to boot.
The scsi has ubuntu on it, which I want to boot, and the sata drive has vista on it.
I have the bios boot order correct (it shows both drives, with the scsi drive first), I have the scsi drive set to scsi-0, and I have boot other device enabled.
It boots into Linux no problem with the sata drive unplugged, so what am I missing?

When the SATA drive is plugged in, does it get to the bootloader for linux? It sounds like the drives may be switching around and linux is looking at the wrong drive for its partition.

If you have just two drives, look at the bootloader for linux; see if it says "hd(0,0)" in the list. If so, you could temporarily change it to "hd(1,0)". All that does is switch it to look for the second drive instead of the first.

I had it screwed up. I was messing with the settings in the SCSI panel, and forgot to switch it back. Put things back to normal, and it reads fine now.
