11. USB, PS/2 Mouse, Infrared, Module Connector (USBMIR, 18-1 pin block)
If you want to use PS/2 mouse, USB, or infrared (IrDA) devices, you need to
purchase an optional USB/MIR connector set. You may use the bundled PS/2
mouse/parallel port connector set if you just want to use a PS/2 mouse. Either
connector set connects to the 18-pin block and mounts to an open slot on your
computer’s chassis. The system will direct IRQ12 to the PS/2 mouse if one is
detected. If not detected, expansion cards can use IRQ12. See PS/2 Mouse Control
in BIOS Features Setup and USB Function in PnP and PCI Setup under BIOS
SETUP. See Second IrDA... connector for details on the infrared connector.
