Do we have the same problem with tpr patching rom (vapic,bin)? It modifies itself too.But a reset will reload it.Correct, but Kevin says "sendkey ctrl-alt-delete" jumps to SeaBIOS's reboot vector without issuing system reset. I am talking about this situation.
That's only if we're in the bios. If an OS has taken over, it will issue a proper reset. If an OS has not taken over (DOS won't, probably) then it isn't Windows and the vapic payload hasn't had a chance to modify itself.
