Since you should be able to setup the BIOS, you still decide which the 
BIOS boot order calls disk 1.

It isn't ambiguous, it is always the same order you set it up in the BIOS.

If it has a boot time boot menu option (i.e. F11 or F12 usually), you 
can change at boot which disk is the MBR the BIOS will look to boot 
from.  That is why I said before you could unplug those 2 disks, install 
10.3 without fear, install GRUB into the MBR of the 3rd disk, and decide 
with the BIOS boot menu which system you boot.
