2.5.1 PS/2 Mouse and PS/2 Keyboard Ports
The mainboard is equipped with an onboard PS/2 mouse (Green)
and PS/2 keyboard (Purple) ports - both at location J11 of the ATX
double deck ports of the mainboard. 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 a
PS/2 keyboard or PS/2 mouse to wake up the system from the S5
state.
To use this function:
1. JP2 must be set to “2-3 On”. Refer to “Jumper Settings for
Selecting the PS/2 Power” in this chapter.
2. “PS2KB Wakeup Select” (“IRQ/Event Activity Detect” field) in the
Power Management submenu of the BIOS must be set
accordingly. Refer to chapter 3 for more information.
Warning:
Make sure to turn off your computer prior to connecting or
disconnecting a mouse or keyboard. Failure to do so may
damage the mainboard.
