Getting a SATA drive in the boot device list

[patmc]

I have an older ThinkCentre an A50 I think (6147 43U) it has a few noisy/small IDE drives and one SATA 1TB drive that was used to get some extra space for images/mp3s.

Currently a mess; my son made it dual boot linux with grub; but that somehow reversed the drive priority and we had to hack the grub boot spec to get the win/xp back.

Win XP is currently alone on the original device drive; been trying to get it over to the SATA (speed/safety).

I'm stuck in that I can't get the SATA device in the boot order list at all via BIOS.

Not sure of the root cause. It shows as IDE 4 in the list, but not in the bootable section.

I've read a bit and may find that my clonezilla copy/move of XP from the original drive to the SATA may still fail (SATA drivers?), but I can't tell for sure if I can't get the drive into the boot list.

What things might cause a SATA drive to refuse being added to the boot list (no action, just a beep, when I try in BIOS setup)?
