Bios doesn't boot unless I press esc-key for diagnostic screen?
#1
After many trial and error I succesfully updated my amd raid option rom with a newer version but bios wont boot unless I press esc-key? My southbridge is a amd sb700 chipset. Laptop is a FSC Xa 3530. Bios is a Phoenix 2.08. I can use Phoenix Bios Editor. I have also unlocked many hidden bios options and disable the splash screen to no avail. The bios doesn't boot without the splash screen and without pressing the esc-key (for diagnostic screen) either. But I would like to use the newest option-rom, too. Can I fix this somehow? I have also read about the possibility to write a loader for the option-rom. Is this possible?

Success! Since I'm using an amd raid rom I post my patch for the misc.bin. I disassembled the misc.bin and permantently activated the esc-key sequence. Eventually it also solves the load to misc.bin error and maybe I can debug my error again and make a better patch?
