Gigabyte GA-MA78LMT-S2H: Chapter 2 BIOS Setup

Chapter 2 BIOS Setup

BIOS (Basic Input and Output System) records hardware parameters of the system in the CMOS on the

motherboard. Its major functions include conducting the Power-On Self-Test (POST) during system startup,

saving system parameters and loading operating system, etc. BIOS includes a BIOS Setup program that

allows the user to modify basic system conguration settings or to activate certain system features. When

the power is turned off, the battery on the motherboard supplies the necessary power to the CMOS to keep

the conguration values in the CMOS.

To access the BIOS Setup program, press the <Delete> key during the POST when the power is turned on.

To see more advanced BIOS Setup menu options, you can press <Ctrl> + <F1> in the main menu of the

BIOS Setup program.

To upgrade the BIOS, use either the GIGABYTE Q-Flash or @BIOS utility.

• Q-Flash allows the user to quickly and easily upgrade or back up BIOS without entering the operating

system.

• @BIOS is a Windows-based utility that searches and downloads the latest version of BIOS from the

Internet and updates the BIOS.

For instructions on using the Q-Flash and @BIOS utilities, refer to Chapter 4, "BIOS Update Utilities."

• Because BIOS ashing is potentially risky, if you do not encounter problems using the current

version of BIOS, it is recommended that you not ash the BIOS. To ash the BIOS, do it with

caution. Inadequate BIOS ashing may result in system malfunction.

• BIOS will emit a beep code during the POST. Refer to Chapter 5, "Troubleshooting," for the beep

codes description.

• It is recommended that you not alter the default settings (unless you need to) to prevent system

instability or other unexpected results. Inadequately altering the settings may result in system's

failure to boot. If this occurs, try to clear the CMOS values and reset the board to default values.

(Refer to the "Load Optimized Defaults" section in this chapter or introductions of the battery/

clearing CMOS jumper in Chapter 1 for how to clear the CMOS values.)

This motherboard incorporates cable diagnostic feature designed to detect the status of the attached LAN

cable. This feature will detect cabling issue and report the approximate distance to the fault or short. Refer to

the following information for diagnosing your LAN cable:

When No LAN Cable Is Attached...

If no LAN cable is attached to the motherboard, the Status elds of all four pairs of wires will show Open

and the Length elds show 0m, as shown in the gure above.

When LAN Cable Is Functioning Normally...

If no cable problem is detected on the LAN cable connected to a Gigabit hub or a 10/100 Mbps hub, the

following message will appear:

Start detecting at Port.....

Link Detected --> 100Mbps

Cable Length= 30m

Link Detected Displays transmission speed.

Cable Length Displays the approximate length of the attached LAN cable.

Note: The Gigabit hub will only operate at a speed of 10/100 Mbps in MS-DOS mode; it will operate at a

normal speed of 10/100/1000 Mbps in Windows mode or when the LAN Boot ROM is activated.

When a Cable Problem Occurs...

If a cable problem occurs on a specied pair of wires, the Status eld will show Short and then length

shown will be the approximate distance to the fault or short.

Example:

Part1-2 Status = Short / Length = 2m

Explanation: A fault or short might occur at about 2m on Part 1-2.

Note: Part 4-5 and Part 7-8 are not used in a 10/100 Mbps environment, so their Status elds will show

Open, and the length shown is the approximate length of the attached LAN cable.
