14.USB, PS/2 Mouse, Infrared (IrDA) Module Connector (18-pin block)

If you want to use USB, PS/2 mouse, or infrared devices, you need to purchase an external connector set. The external 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 of the BIOS SOFTWARE. See Second Infrared... connector for details on the infrared connector.
