Generates a pached bios for the Asus KGPE-D16 dual socket Opteron motherboard.

The KGPE-D16 only supports the Opteron 6300 series cpus after a certain bios update, which are the cpus I have. Instead of analyzing all bioses to see if I could just flash a single bios version (i.e. bioses aren't deltas, but complete), I elected to assume that the bioses were deltas and to merge patches of all bios versions into a single bios. This method worked for me.

This script relies on bsdiff / bspatch to do binary diffing and patching. On Fedora 36 (at the time of this writing), the package is bsdiff.

This script does the following:

• creates a directory called $HOME/KGPE-D16/
• downloads all the bios archives to the above directory
• extracts them, but leaves the embedded EXE file
• renames the bioses to numbers padded to two places
• incrementally patches the earlies bios with the next bios
• incrementally applies this patch to the earliest bios
• continues until the most recent bios, and produces patched-final.rom
