Hi Diego, sorry for delaying my answer, but I found some tool which could do the modding for me, I just need the correct syntax to do this.
The tool is called "Intel FPT", or "Intel Flash Programming Tool", so since it is from Intel, you should be able to pass me the full syntax if the OROM is called "orom.bin".
ATM. the tool denies access from the host CPU to the flash area, so please forward me this command, too.
Sincerely
IDDQD
EDIT: Almost forgot: Indeed this is a bug in the ME firmware I have. Because of that I want to upgrade the firmware on my risk to 8.x. I already have the proofed working firmware on my disk, I only need the commands. ;-)
