Is there a quick way to confirm settings?

I want to be able to confirm that every setting in a BIOS is identical to another unit. I was wondering if there was a way to grab the BIOS checksum and compare? and if there is would the checksum be identical accross different units?
Any ideas?
Thanks

if you mean by settings the actual settings made by the user then you have to dump the contents of the CMOS (often called NVRAM) which is NOT a part of the bios but a battery powered memory in the southbridge. it can be read by using memory mapped ports.
here are the sources to an nvram dumping tool. this is a good starting point to write your own application.
