There is a flag at EEPROM which enables a special diagnostic mode at startup.
Note: This flag is enabled on Proto/DECR. It allows extra debug messages (INFO/WARNING/ERROR)
Pseudo-code:
def check_bootrom_diag_mode(mode, param) diag_mode = get_eeprom_bootrom_diag() if diag_mode & 0x1: if diag_mode & 0x100: return 0 mode = (diag_mode >> 3) & 0x1 param = (diag_mode >> 3) & 0x1 else: mode = (diag_mode >> 1) & 0x1 param = -1 return 1
