Safety information

Electrical Safety Before installing or removing signal cables, ensure that the power cables for the system

unit and all attached devices are unplugged.

To prevent electrical shock hazard, disconnect the power cable from the electrical outlet before relocating the system.

When adding or removing any additional devices to or from the system, ensure that the power cables for the devices are unplugged before the signal cables are connected. If possible, disconnect all power cables from the existing system before you add a device.

If the power supply is broken, do not try to fix it by yourself. Contact a qualified service technician or your dealer.

Operation Safety Any mechanical operation on this server must be conducted by certified or experienced

engineers.

Before operating the server, carefully read all the manuals included with the server package.

Before using the server, ensure all cables are correctly connected and the power cables are not damaged. If any damage is detected, contact your dealer as soon as possible.

To avoid short circuits, keep paper clips, screws, and staples away from connectors, slots, sockets and circuitry.

Avoid dust, humidity, and temperature extremes. Place the server on a stable surface.

Heavy System CAUTION! This server system is heavy. Ask for assistance when moving or carrying the system.

This product is equipped with a three-wire power cable and plug for the users safety. Use the power cable with a properly grounded electrical outlet to avoid electrical shock.

4.2 BIOS setup program This motherboard supports a programmable firmware chip that you can update using the provided utility described in section 5.1 Managing and updating your BIOS.

Use the BIOS Setup program when you are installing a motherboard, reconfiguring your system, or prompted to Run Setup. This section explains how to configure your system using this utility.

Even if you are not prompted to use the Setup program, you can change the configuration of your computer in the future. For example, you can enable the security password feature or change the power management settings. This requires you to reconfigure your system using the BIOS Setup program so that the computer can recognize these changes and record them in the CMOS RAM of the firmware chip.

The firmware chip on the motherboard stores the Setup utility. When you start up the computer, the system provides you with the opportunity to run this program. Press during the Power-On Self-Test (POST) to enter the Setup utility; otherwise, POST continues with its test routines.

If you wish to enter Setup after POST, restart the system by pressing + + , or by pressing the reset button on the system chassis. You can also restart by turning the system off and then back on. Do this last option only if the first two failed.

The Setup program is designed to make it as easy to use as possible. Being a menu-driven program, it lets you scroll through the various sub-menus and make your selections from the available options using the navigation keys.

The default BIOS settings for this motherboard apply for most conditions to ensure optimum performance. If the system becomes unstable after changing any BIOS settings, load the default settings to ensure system compatibility and stability. Press and select Yes to load the BIOS default settings.

The BIOS setup screens shown in this section are for reference purposes only, and may not exactly match what you see on your screen.
