2.12 Connecting PS/2, USB, Video, Serial and Parallel Ports
This board includes ports for PS/2 mouse and keyboard, USB, video, serial and parallel ports. Please
note that the upper PS/2 port is the mouse port, and the lower PS/2 port is for the keyboard (see
Figure
2.7
below).
The PS/2 connectors are probably quite familiar to you, while the USB connectors may not be. A USB
port can function as a serial, parallel, mouse, keyboard, or joystick port. It is capable of supporting up to
127 daisy-chained peripheral devices.
Figure 2.7
(below) shows the ATX double row connectors on this
board. Serial Port 1, as well as the other ports, are labeled in the image below.
A note of caution about installing external devices
When plugging in the keyboard and mouse, or when plugging anything into any external port, make sure
that the power is off. Connecting these devices and ports while the power is on is called “hot plugging”,
and may damage your system.
2.13 Connecting the power supply
This motherboard requires an ATX power supply. Tyan recommends using one that conforms to industry
standard Revision 2.01, and is
300 watts or higher
. The photos below show the ATX power connector
before (
Figure 2.8a
) and after (
Figure 2.8b
) it has been plugged in. The clip on the power connector
should lock over the tab on the onboard connector. You shouldn’t be able to plug the power connector in
more than one way, but just to be safe, make sure it looks like
Figure 2.8b
. Make certain you do not miss
connecting any of the pins because if you do, you will void your warranty and possible cause damage to
yourself and/or your motherboard. After connecting the power, make sure the connector is seated firmly
into its socket so it will not become loose or fall off when the computer is jostled or moved.
