[coreboot] ASUS M4A77TD-PRO. No boot, nothing on the serial port. I'm quite lost.

No, there isn't... Oh,wait. It's there. I spent most of yesterday's
afternoon looking at the original code for asrock, not the file you
sent me (I compiled the one you sent me but then compared the original
one to the coreboot code, because I compile on the M4A77TD-PRO board
on the serial port but look at the code in a laptop with VGA ).  No
wonder there were so many differences I didn't know which ones to
pick...  Some things didn't make sense...

I'll look again today.

OK.
