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, re-establishes the connection after an over-current condition is removed.
The keyboard controller contains the AMI Megakey keyboard and mouse controller
code, which provides the keyboard and mouse control functions, and supports
password protection for power on/reset. A power on/reset password can be
specified in Setup.
The keyboard controller also supports the hot-key sequence <Ctrl><Alt><Del> for a
software reset. This key sequence resets the computer’s software by jumping to the
beginning of the BIOS code and running the Power-On Self Test (POST).
