Keyboard and Mouse Interface

PS/2 keyboard and mouse connectors are located on the back panel. The +5 V lines to these
connectors are protected with a PolySwitch

circuit that, like a self-healing fuse, reestablishes the

connection after an overcurrent condition is removed.

NOTE

The keyboard is supported in the bottom PS/2 connector and the mouse is supported in the top
PS/2 connector. Power to the computer should be turned off before a keyboard or mouse is
connected or disconnected.

The keyboard controller contains the AMI keyboard and mouse controller code, provides the
keyboard and mouse control functions, and supports password protection for power-on/reset. A
power-on/reset password can be specified in the BIOS Setup program.
