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* fuse 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 American MegaTrends* (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.
