A
PS/2 Keyboard and Mouse 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 set the soft-off feature working properly.
