    I have not seen that error before and it does not sound good. A quick Google of that error brings up nothing useful. 304 sounds very much like a browser error. Did you power down the PC and then power it up from scratch and press F10 right at the start?

Running a serial console in a terminal I don’t have function keys, esp no F2 to access the BIOS. ESC-2 doesn’t work. ???

    I take it the Intel board you are using does not have USB ports so you cannot connect a keyboard.
