I am talking about SW Raid also.  Now, what happens when your BIOS fails 
to read the MBR from the first mirror and doesn't try the second because 
it sees the first?

I see this problem, and I do not know how to fix it without either 
replacing the BIOS or installing a PCI disk controller that handles this 
scenario properly.

Let me repeat, if your BIOS doesn't look hard enough for a MBR, you will 
never get to the bootloader.

I'm looking for solutions, do you understand the problem I am 
describing?  I hope so, because otherwise you are just denying a valid 
failure case.

Solutions wanted.
