What could make a computer not recognize a serial keyboard in the BIOS

I've got an old POS system that won't recognize a control panel which is essentially a custom keyboard (functions instead of letters, etc) that hooks in via a serial port.

I've tried replacing pretty much everything involved (keyboard, RS232 cable and serial expansion card) but it's not detected on POST or when the system boots into Win98.

Any ideas? Is there a legacy BIOS setting I'm missing?
 
serial expansion card? those may need a driver (it shouldn't) for Win98 to see it, but if the BIOS isn't seeing it then I would look into the motherboard. Maybe you have a bad UART or something...


Of course without seeing the BIOS there is no way I could comment on what settings to check... maybe fool with plug-n-play OS if the option is there?
