(1) PS/2 Mouse IRQ12 Setting (JP8)
The default of <Enabled> allows the system detecting a PS/2 mouse on boot. If detected, IRQ12 will be used for
the PS/2 mouse. IRQ12 will be reserved for expansion cards and therefore the PS/2 mouse will not function.

CAUTION:
After adjusting the JP8 correctly, the user must set the <PS/2 Mouse Support> option to Enabled in the
BIOS <Advanced CMOS Setup> Menu. Then the PS/2 mouse can be used.
(2) PS/2 Mouse Connector (CN6 & J7)
To use the PS/2 interface, an adapter cable has to be connected to the CN6 and J7 (6-pin header type) connector.
This adapter cable is mounted on a bracket and is included in your AR-B1476 package. The connector for the
PS/2 mouse is a Mini-DIN 6-pin connector. Pin assignments for the PS/2 port connector are as follows:
