If the BIOS can't even see the drives, then they're not there as far as 
the motherboard is concerned. No amount of messing with *nix will 
address that. This is a hardware/firmware problem, not an OS problem.

Things to check:

- Go over all your cables again.

- Make sure that there isn't some weird conflict with that BIOS not 
supporting those drive types.

- If you fully disconnect the BSD drives, will it boot into windows at all?

- Do the drives have any jumpers that control things like SSC, PUIS, or 
alternate PHY modes? Some boards don't support all options.

- Do the drives have dual sata+molex power plugs? Some drives 
(especially WD drives) with dual power will do special delayed/staggered 
spinup stuff and wait for an init signal over the sata data cable before 
starting, so if the BIOS doesn't send what the drive is expecting, 
nothing will happen.

Sounds like whoever 'refurbished' this machine either is screwing with 
you or doesn't know what they're doing. There should be a physical 
jumper or switch somewhere on the board that can forcibly reset the BIOS 
to factory defaults if you set it the right way at the right time; hunt 
down the board's manual for a step-by-step. Sometimes just pulling the 
battery for an hour will do it, depending on the BIOS and board.
