17. PS/2 Mouse, USB, Infrared Connector (18-pin block)
If you are using a PS/2 mouse, USB, or Infrared devices, you must purchase an
optional external connector set. The external connector set connects to the 18
pin block and mounts to an open slot on your computer's chssis. 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 Funtion” in PnP and PCI Setup of the BIOS SOFTWARE. See “Second
Infrared” connector for details on the infrared connector.
