Everything that I've tried at a BIOS level has worked. Nothing that I've
tried at a hardware level has.

The RS232 port is definitely BIOS compatible. I've played with it and
done some playing with the screen (I wrote a small terminal emulator
using BIOS calls for both the screen and the serial port). Before the
requests start pouring in, it is not fit for external consumption. No,
I won't post it.
