2.4 Rear Panel I/O Ports

2.4.1 PS/2 Mouse and PS/2 Keyboard Ports
The system board is equipped with an onboard PS/2 mouse
(Green) and PS/2 keyboard (Purple) ports - both at location J1 of
the ATX double deck ports of the system board. The PS/2 mouse
port uses IRQ12. If a mouse is not connected to this port, the
system will reserve IRQ12 for other expansion cards.
The Wake-On-PS/2 Keyboard/Mouse function allows you to use the
PS/2 keyboard or PS/2 mouse to wake up a system from the S3/
S4/S5 state. "PS2KB Wakeup from S3/S4/S5" and "PS2MS Wakeup
from S3/S4/S5" ("PM Wake Up Events" field) in the Power
Management Setup submenu of the BIOS must be set accordingly.
