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.
