Gigabyte Ga945gcmxs2 User Guide

							BIOS Setup - 31 -
English
BIOS (Basic Input and Output System) includes a CMOS SETUP utility which allows user to configure
required settings or to activate certain system features.
The CMOS SETUP saves the configuration in the CMOS SRAM of the motherboard.
When the power is turned off, the battery on the motherboard supplies the necessary power to the CMOS
SRAM.
When the power is turned on, press the  button during the BIOS POST (Power-On Self Test) will
take you to the CMOS SETUP screen. You can enter the BIOS setup screen by pressing Ctrl + F1.
If you wish to upgrade to a new BIOS, either GIGABYTEs Q-Flash or @BIOS utility can be used.
Q-Flash allows the user to quickly and easily update or backup BIOS without entering the operating
system.
@BIOS is a Windows-based utility that does not require users to boot to DOS before upgrading BIOS but
directly download and update BIOS from the Internet.

1. If you dont find the settings you want, press Ctrl+F1 to access advanced options.
2. Select the Load Optimized Defaults item in the BIOS Setup when somehow the system
    is not stable as usual.  This action makes the system reset to the default settings for
    stability.
3. The BIOS Setup menus described in this chapter are for reference only and may differ from
    the exact settings for your motherboard.

Base Memory
The POST of the BIOS will determine the amount of base (or conventional) memory installed in the
system.
The value of the base memory is typically 512 K for systems with 512 K memory installed on the
motherboard, or 640 K for systems with 640 K or more memory installed on the motherboard.
Extended Memory
The BIOS determines how much extended memory is present during the POST.
This is the amount of memory located above 1 MB in the CPUs memory address map.

SMART LAN (LAN Cable Diagnostic Function)
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 0.0m,  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:
Link DetectedDisplays 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 specified pair of wires, the Status field will show Short and the
length shown will be the approximate distance to the fault or short.
Example: Pair1-2 Status = Short / Length  =  1.6m
Explanation: A fault or short might occur at about 1.6m on Pair 1-2.
Note: Pair 4-5 and Pair 7-8 are not used in a 10/100 Mbps environment, their Status fields will
show Open, and the length shown is the approximate length of the attached LAN cable.
