Hi Cory
Just found this. Gigabyte's DualBios patent: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=... 2Fnetahtml%2Fsearch-adv.htm&r=8&f=G&l=50&d=PALL&S1=6651188.UREF.&OS=ref/66 51188&RS=REF/6651188
Thanks for digging this up. This patent is a joke: "Certain variations would be apparent to those skilled in the art, which variations are considered within the spirit and scope of the claimed invention.". Yeah great.
The description is very vague and not very helpful. I think the only thing it shows is that this patent system is a job security program for lawyers but not helpful in the advance of the mankind.
The only interesting thing i found is that they seem to use a checksum or s.t. to test if the bios image is valid.
