to dump the system bios, use:
dd if=mem of=/tmp/bios_dump bs=1024 count=64 skip=960
then use eg. 'ndisasm' from nasm, it produces correct 16 bit code too.
(dont know wether objdump has been fixed recently) This should give you a
way to look at the ideas implemented by the BIOS. Dont use the code, thats
copyright protected.
