The following illustration displays the motherboard I/O port array.

Type of Port	Function
PS/2 Mouse connector	The system will direct IRQ12 to the PS/2 mouse if
	one is detected. If not detected, IRQ12 can be used
	for expansion slot.

	PS/2 plug (mini DIN). This connector will not
	allow standard AT size (large DIN) keyboard

	simultaneous connections of 2 USB devices.
Serial Port connector (9-pin male)	This serial port can be used for pointing devices or
	other serial devices. See BIOS setup.
VGA connector (15-pin female)	The VGA port connects display devices such as a
	monitor. See the BIOS setup.

	82546GB Anvik2 dual channel Gigabit Ethernet
	Controller, depending on the manufacturing option.
