Ah, so the first disk, as defined by the BIOS, may not be the one which I'd call first, the Master Disk at the end of the primary flat cable.
Since you should be able to setup the BIOS, you still decide which the BIOS boot order calls disk 1.
In my system, without RAID, there is no ambiguity which one is first, it has WinME and YaST Partitioner lists it as hda (SuSE 10.2) or sda (10.3).
It isn't ambiguous, it is always the same order you set it up in the BIOS.
Next week I get my hands on the system with 2 disks in RAID 1 for WinXP and a third disk with a SuSE partition. Then I can see which one is defined first by the BIOS and how YaST Partitioner calls it.

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.
