Sorry - it's there now. It's in "tools/buildrom.py" in the repo at: git clone git://git.linuxtogo.org/home/kevin/seabios.git It's also at: http://git.linuxtogo.org/?p=kevin/seabios.git;a=blob;f=tools/buildrom.py;h=19b715adfe491aa0fd54fbae4d35b1d1a0abf346;hb=HEAD The script pads a rom to 512 bytes, sets the rom length, and uses byte 7 as a checksum. It wasn't designed for sgabios, but looks like it will work. -Kevin -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
