I have compiled an option rom but my bios doesn't seem to see it neither to load or something. My option rom starts with $55, $aa and checksum is 0. I also have a device id, vendor id, a pcir structure and pnp structure. In my option rom I want to print some information from the bios to the screen. I don't know much asm just a copy and past work. Thank you for your help! My bios is a phoenix bios and I want to update my amd raid driver but bios is nasty to me!
