1-10.4    PS/2 Keyboard and Mouse Interface 
PS/2 keyboard and mouse connectors are located on the back panel of the 
motherboard. The +5 V lines to keyboard and mouse connectors are 
protected with a fuse that prevents motherboard components from being 
damaged when an over-current condition occurs. 
Note 
The mouse and keyboard can be plugged into either PS/2 connector. 
Power to the computer should be turned off before a keyboard or mouse is 
connected or disconnected. 
The keyboard controller contains code, which provides the traditional 
keyboard and mouse control functions, and also supports Power On/Reset 
password protection. Power On/Reset password can be specified in the 
BIOS Setup program. 
The keyboard controller also supports the hot-key sequence 
<Ctrl><Alt><Del>, 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). 
1-10.5  Infrared Support 
On the front panel I/O connector, there are six pins that support Hewlett 
Packard HSDL-1000 compatible infrared (IR) transmitters and receivers. 
In the Setup program, Serial Port B can be direct4d to a connected IR 
device. (In this case, the Serial Port B connector on the back panel cannot 
be used.) The IR connection can be used to transfer files to or from 
portable devices like laptops, PDAs, and printers. The Infrared Data 
Association (IrDA) specification supports data transfers of 115Kbits/sec at 
a distance of 1 meter.
