The reason I ask about the BIOS is that the 5160 calls SW1 "unused" and the XT documentation seems to imply that you must have a floppy controller installed.
I haven't looked, but would someone put a 5160 BIOS ROM in a 5150 system board? I guess if that is the case, it makes sense, but if not and it is still a 5150 BIOS ROM in this thing, what's making it go nuts?
