Just to be entirely certain you are saying what I think, if you set the 
BIOS the way you want it on one, then copy it to others, that it does 
not work?

I would think that if you are copying all of the BIOS settings, then the 
checksum should be right.

I think you should ask this question on nahant-list because I'm sure 
there's an AMD bloke there who's done exactly this. It might be that 
someone there can advise how to calculate the checksum and fix it.
