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 / Windows 98 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 set the soft-off feature
working properly.
