1 1. Motherboard Pin definition E11133. Revised Edition v2. December 2015. 1 2015/12/28 17:21:46. Contents Motherboard Pin definition 1-1. 1 1-3. 2 1-4. 3 Internal 1-6. 4 Onboard 1-16. 5 Onboard buttons and 1-17. 1-2 Motherboard Pin definition 2 2015/12/28 17:21:46. 1 Headers 1. Clear RTC RAM (2-pin CLRTC). This header allows you to clear the Real Time Clock (RTC) RAM in CLRTC. CMOS. You can clear the CMOS memory of date, time, and system setup +3V_BAT. parameters by erasing the CMOS RTC RAM data. The onboard button GND. cell battery powers the RAM data in CMOS, which include system setup information such as system passwords.

2 PIN 1. To erase the RTC RAM: 1. Turn OFF the computer and unplug the power cord. 2. Use a metal object such as a screwdriver to short the two pins. 3. Plug the power cord and turn ON the computer. 4. Hold down the <Del> key during the boot process and enter BIOS setup to re- enter data. If the steps above do not help, remove the onboard battery and short the two pins again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery. You do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the CPU Parameter Recall ( ) feature.

3 Shut down and reboot the system, then the BIOS automatically resets parameter settings to default values. 2. RTC Battery header (2-pin BATT_CON). This connector is for the lithium CMOS battery. BATT_CON. VBAT. GND. PIN 1. 3. Chassis intrusion header (4-1 pin CHASSIS). This header is for a chassis-mounted intrusion detection sensor or CHASSIS. switch. Connect one end of the chassis intrusion sensor or switch cable Chassis Signal to this connector. The chassis intrusion sensor or switch sends a high - +5 VSB_MB. level signal to this connector when a chassis component is removed or replaced.

4 The signal is then generated as a chassis intrusion event. GND. By default, the pin labeled Chassis Signal and Ground are shorted with a jumper cap. Remove the jumper caps only when you intend to use the chassis intrusion detection feature. Motherboard Pin definition 1-3. 3 2015/12/28 17:21:46. 2 Jumpers 1. Clear RTC RAM (3-pin CLRTC). This jumper allows you to clear the Real Time Clock (RTC). CLRTC. RAM in CMOS. You can clear the CMOS memory of date, time, 1 2 2 3. and system setup parameters by erasing the CMOS RTC RAM. Normal Clear RTC. data. The onboard button cell battery powers the RAM data in (Default).

5 CMOS, which include system setup information such as system passwords. To erase the RTC RAM: 1. Turn OFF the computer and unplug the power cord. 2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3. for about 5~10 seconds, then move the cap back to pins 1-2. 3. Plug the power cord and turn ON the computer. 4. Hold down the <Del> key during the boot process and enter BIOS setup to reenter data. Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. Removing the cap will cause system boot failure!

6 If the steps above do not help, remove the onboard battery and move the jumper again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery. You do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the CPU Parameter Recall ( ) feature. Shut down and reboot the system so the BIOS can automatically reset parameter settings to default values. 2. Intel ME jumper (3-pin DIS_ME). This jumper allows you to enable or disable the Intel ME DIS_ME. function. Set this jumper to pins 1-2 to enable (default) the Intel 1 2 2 3.

7 ME function and to pins 2-3 to disable it. Normal Disable ME. (Default). Disable the Intel ME function before updating it. 1-4 Motherboard Pin definition 4 2015/12/28 17:21:47. 3. USB device wake-up (3-pin USBPWF). Set these jumpers to +5V to wake up the computer from S1 sleep USBPWF. mode (CPU stopped, DRAM refreshed, system running in low power 1 2 2 3. mode) using the connected USB devices. Set to +5 VSB to wake up from S3 and S4 sleep modes (no power to CPU, DRAM in slow +5V +5 VSB. refresh, power supply in reduced power mode). (Default). The USB device wake-up feature requires a power supply that can provide 500mA on the +5 VSB lead for each USB port; otherwise, the system would not power up.

8 The total current consumed must NOT exceed the power supply capability (+5 VSB). whether under normal condition or in sleep mode. 4. Keyboard and USB device wake up (3-pin KB_USBPWB). This jumper allows you to enable or disable the keyboard and KB_USBPWB. USB device wake-up feature. When you set this jumper to pins 2-3 (+5 VSB), you can wake up the computer by pressing a key on 2 3. 1 2. the keyboard. This feature requires an ATX power supply that can +5V +5 VSB. supply at least 1A on the +5 VSB lead, and a corresponding setting (Default). in the BIOS. 5.

9 Display panel backlight power selector (3-pin BLKT_PWR_SEL). BLKT_PWR_SEL. Pins Setting 3. 2. 2. 1-2 (Default) 12V. 1. 12V 19V. 2-3 19V (Default). 6. Display panel VCC power selector (VCC_PWR_SEL). VCC_PWR_SEL. Pins Setting 1. 2. 1 (Default) 3V 3V 5V 12V. 3. 2 5V (Default). 3 12V. 7. LVDS panel/eDP selector (3-pin FPD_SEL). FPD_SEL. Pins Setting 3. 1-2 (Default) LVDS. 2. 2. 1. 2-3 eDP for LVDS for eDP. (Default). Motherboard Pin definition 1-5. 5 2015/12/28 17:21:47. 3 Internal Connectors 1. Serial port connector (10-1 pin COM). This connector is for a serial (COM) port.
