I've tried AMIBCP 2.25 Beta and 2.4.x, and recieved "Rom header not found" errors, I'm guessing they aren't compatable with the generation of BIOS I'm trying to edit, however I can't find any other version of AMIBCP (www.ami.com isn't working for me presently, but I'm not sure if it would help). Just wondernig if anyone has a suggestion as to what to try next.
