The best way to flash is under DOS with afudos. Try a bios recovery. 1. Create a bootble floppydisk. 2. Copy "afudos" to floppydisk. 3. Create a textfile with "A:\afudos /IAMIBOOT.ROM /P /B /N /C /R" as content. 4. Save created textfile as "AUTOEXEC.BAT" to floppydisk. 5. Copy disered biosfile to floppydisk, rename it as "AMIBOOT.ROM". 6. Cold start the computer you want to flash, and press "ctrl+home" keys simultaneously.
Use the latest version of Everest, it could be that the mod isn't working. In that case I can't do anything else for you, it is a quite old mobo.
Has anyone here had success moding the ECS A780GM-A mobo? If so, I'd like to know how you did it. thanks!!
