I have never used this motherboard... there could be bugs in the BIOS, but
I usually assume such bugs are unlikely.  This is apparently a server
motherboard, which is more likely to have an "ignore keyboard" option to
bypass the keyboard function test on boot. I don't think this option
usually disables the keyboard, though.

Note that unplugging and plugging in a PS/2 keyboard while the computer is
powered can burn out the keyboard electrical connection.  I have
experienced this before.  I think it is also possible that the keyboard
interface on the motherboard may get burned out by such mistreatment,
though I have (fortunately) not experienced this. :)

In most cases, you are disabling a serial port because you want to use the
interrupts and/or io ports it uses for a different device.  Only the BIOS
can disable the hardware in a fashion that will allow this.  (Not even
"boot.ini" on an NT system can do this.)
