-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello,
I think I can CC the coreboot list too. I wanted to extract the Asrock "AMI" ROM found in the 939A785GMH/128M. I had to add following changes to the ami.c 1) there is a flag for uncompressed module 0x90 instead of 0x80 dunno why 2) if the module size in rom > 0xffff some bytes before the structure are used as size, the second number looks like crc maybe. 3) the type of 0x40 and 0x60 is AMD CIM-X but it has compress set, but those modules are not. Signed-off-by: Rudolf Marek <[email protected]> Maybe you will need bit to re-arrange patch...
