A
PS/2 Mouse & Keyboard Connector
The Mainboard provides two on-board PS/2 connectors, one
for the keyboard, and one for the mouse. PS/2 devices all have
a standard 6-pin round shape connector. If you are already
using a PS/2 mouse or keyboard, simply plug them into the
corresponding connector. No jumper settings are necessary.
B
ATX Power Supply Connector
The Mainboard provides a single 20-pin ATX power
supply connector, which incorporates standard +5V and
+12V, 3.3V and soft-on/off signals. With a power supply that
supports remote power on/off, the mainboard can turn off the
system power through software control, such as the shutdown
command in the Windows 95 Start Menu. The BIOS system
will turn the system power off when it receives the proper APM
command from the OS. APM must be enabled in the BIOS
and OS systems in order to said the soft-off feature working
properly.
