Agreed, there is an inconsistancy in the bios mapping and Linux's mapping, in Linux grub-install
--recheck shows /dev/sda is hd3, but I can edit the command line from the old IDE drive's grub
to boot from hd2 and it boots the scsi drive.  So from the BIOS it's hd2.

But still, I can't seem to get grub on the sda drive.  I've tried numerous things, but it
just stalls before it'd show it's loading the grub stages.  I'm at least assuming I can't get
grub installed, it might be the BIOS isn't loading the MBR from it for some reason.

Motherboard is a MSI Ksomething Platinum with AMD64, so it's a pretty new motherboard, I don't
think it would have issues booting from scsi.

Did I misunderstand you?  Any other suggestions?
