Gigabyte GA-945GCM-S2L: Chapter 2 BIOS Setup

Chapter 2 BIOS Setup: Gigabyte GA-945GCM-S2L

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 configuration 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 configuration 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 flashing is potentially risky, if you do not encounter problems using the

current version of BIOS, it is recommended that you not flash the BIOS. To flash the BIOS,

do it with caution. Inadequate BIOS flashing 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 introduc-

tions 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 fields of all four pairs of wires will show

Open and the Length fields show 0m, as shown in the figure 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

Link Detected Displays transmission speed

Note: The Gigabit hub will only operate at a speed of 10/100Mbps 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 specified pair of wires, the Status field will show Short and

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

Example: Pair1-2 Status = Short / Length = 2m

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

Note: Pair 4-5 and Pair 7-8 are not used in a 10/100 Mbps environment, so their Status fields will

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

Only for GA-945GCM-S2L.
