It might be not the serial port, to which the loader talks. The supermicro boards I dealt with, have a feature of VGA text mode redirection to the serial port. This is how bios redirection usually works. You could look at some bios knob which controls the point where the said redirection is stopped. It should be like 'after the OS takes the control', and not 'forever'. For BIOS, the loader is OS.
