Chapter 2 BIOS Setup

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 <Del> 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 GIGABYTE's 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.

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 LAN Cable Is Functioning Normally. 1. If no cable problem is detected on the LAN cable connected to a Gigabit hub, the Status fields of Pair 1-2, Pair 3-6, Pair 4-5, and Pair 7-8 will show Normal and the Length fields will show N/A,as shown in the figure above. 2. If no cable problem is detected on the LAN cable connected to a 10/100 Mbps hub, the Status fields of Pair 1-2 and Pair 3-6 will show Normal and the Length fields will show N/A. However, because Pair 4-5 and Pair 7-8 are not used in a 10/100 Mbps environment, their Status fields will show Short or Open, and the length shown is the approximate length of the attached LAN cable. When a Cable Problem Occurs. If a cable problem occurs on a specified pair of wires, the Status field will show Short or Open and the length shown will be the approximate distance to the fault or short. For example, if it shows Pair1-2 Status = Short / Length = 1.6m, it means that a fault or short might occur at about 1.6m on Pair 1-2. 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.

4-1-2 Xpress Recovery2 Introduction
Xpress Recovery2 is designed to provide quick backup and restoration of hard disk data. Supporting Microsoft operating systems including Windows XP/2000/NT/98/Me and DOS, and file systems including FAT16, FAT32, and NTFS, Xpress Recovery2 is able to back up data on hard disks on PATA and SATA IDE controllers. After Xpress Recovery2 is executed from CD-ROM for the first time, it will stay permanent in your hard disk. If you wish to run Xpress Recovery2 later, you can simply press F9 during system bootup to enter Xpress Recovery2 without the CD-ROM.

System requirements:

1. Intel x86 platforms 2. At least 64M bytes of system memory 3. VESA-supported VGA cards
How to use the Xpress Recovery2
Initial access by booting from CD-ROM and subsequent access by pressing the F9 key: Steps: After entering BIOS Setup, go to Advanced BIOS Feature and set to boot from CD-ROM. Save the settings and exit the BIOS Setup. Insert the provided driver CD into your CD-ROM drive. Upon system restart, the message which says "Boot from CD/DVD:" will appear in the bottom left corner of the screen. Press any key to enter Xpress Recovery2. After the steps above are completed, subsequent access to Xpress Recovery2 can be made by simply pressing the <F9> key during system power-on.

. Boot from CD/DVD: Press any key to startup XpressRecovery2.. Award Modular BIOS v6.00PG, An Energy Star Ally Copyright (C) 1984-2006, Award Software, Inc. Intel I945 BIOS for 945GZM-S2 DC. <DEL>:BIOS Setup/Q-Flash, <F9>: Xpress Recovery2, <F12>: Boot Menu 11/24/2006-I945-6A79TG0RC-00

The Main Screen of Xpress Recovery2

1. RESTORE:

Restore the backed-up data to your hard disk. (This button will not appear if there is no backup file.)

2. BACKUP:

Back up data from hard disk.

3. REMOVE:

Remove previously-created backup files to release disk space. (This button will not appear if there is no backup file.)

4. REBOOT:

Exit the main screen and restart the system.

Limitations:

1. 2. 3. Not compatible to Xpress Recovery. For the use of Xpress Recovery2, a primary partition must be reserved. Xpress Recovery2 will store the backup file at the end of the hard disk, so free space available on the hard disk for the backup file must be allocated in advance. (A minimum 4GB is recommended but the actual space is dependent on the size of the data to be backed up) 4. Capable of backing up hard disks installed with Windows operating systems including DOS and Windows XP/2000/NT/9x/Me. 5. USB hard disks are currently not supported. 6. Does not support RAID/AHCI (class code 0104/0106) hard disks. 7. Capable of backing up and restoring only the first physical hard disk. Hard disks detection sequence is as follows: a. PATA IDE primary channel b. PATA IDE secondary channel c. SATA IDE channel 1 d. SATA IDE channel 2 e. SATA IDE channel 3 f. SATA IDE channel 4

Precautions:

1. 2. 3. 4. When using hard disks with more than 128G under Windows 2000, be sure to execute the EnableBigLba.exe program from the driver CD before data backup. It is normal that data backup takes longer time than data restoration. Xpress Recovery2 is compliant with the GPL regulations. On a few motherboards based on Nvidia chipsets, BIOS update is required for Xpress Recovery2 to correctly identify RAID and SATA IDE mode. Please contact your motherboard manufacturer.

Using the Q-FlashTM utility:
This section tells you how to update BIOS using the Q-Flash utility. As described in the "Before you begin" section above, you must prepare a floppy disk having the BIOS file for your motherboard and insert it to your computer. If you have already put the floppy disk into your system and have entered the Q-Flash utility, please follow the steps below to flash BIOS.

Steps:

1. Press arrow buttons on your keyboard to move the light bar to "Load Main BIOS from Floppy" item in the Q-Flash menu and press Enter button. Later, you will see a box pop up showing the BIOS files you previously downloaded to the floppy disk. If you want to save the current BIOS for backup purpose, you can begin Step 1 with "Save Main BIOS to Floppy" item. 2. Move to the BIOS file you want to flash and press Enter.
In this example, we only download one BIOS file to the floppy disk so only one BIOS file, 8KNXPU.Fba, is listed.
Please confirm again you have the correct BIOS file for your motherboard.
