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 Connectors
The Mainboard provides 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 / ACPI command
from the OS. APM / ACPI must be enabled in the BIOS and
OS systems in order to set the soft-off feature working properly.
This Pentium 4 Mainboard also provides a 4-pin power supply
connector, which incorporates additional +12V power for the
CPU power circuitry.
