I'm not a bios expert and what I've seen hasn't been consistent enough 
to generalize, but in the best circumstances the bios will see a list of 
available devices and let you pick the order to try booting them.  Since 
add-in cards supply their own bios, this may be at the card level or it 
may actually see the individual attached devices. I'm not sure how the 
rest of the disks are mapped after one starts to boot - or if all 
machines do it the same way.
