OK.. unfortunately not really much help except confirming that it is in the 
BIOS/loader somewhere..

I believe the loader does look at the drives the BIOS presents to it, certainly 
at the very least it tries to find something to boot off :)

However, even if it is looking on every disk for partitions it should only take 
a second or so (unless one of the drives is broken I suppose).

I have seen BIOSen not boot reliably when external RAID cards are present.. 
Generally their quality is quite variable :(
