Glossary
A PS/2 Mouse & Keyboard ConnectorThe 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 ConnectorsThe 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.20-pin ATX Power Supply ConnectorPin Signal Name Pin Signal Name1 +3.3V 11 +3.3V2 +3.3V 12 -12V3 Ground 13 Ground4 +5V 14 PW_ON5 Ground 15 Ground6 +5V 16 Ground7 Ground 17 Ground8 PWRGOOD 18 -5V9 +5VSB 19 +5V10 +12V 20 +5VGlossaryPage 42 Mainboard User's Manual
