DDRintroduction Established on the existing SDRAM industry infrastructure, DDR (Double Data Rate) memory is a high performance and cost-effecive solution that allows easy adoption for memory vendors, OEMS and system integrators. DDR memory is a sensible evolutionary solution for the PC industry that builds on the existing SDRAM infrastructure, yet makes awesome advances in solvingihe system performance botleneck by doubling he memory bandwidth. DDR SDRAM wi offer a superior solution and migration path from existing SDRAM designs due to its availabiit, pricing and overal market support. PC2100 DDR memory (DDR266) doubles the data rate through reading and writing at both the rising and falling edge of he clock, achieving data banduidth 2X greater than PC133 when running with he same DRAM clock frequency. Wih peak band- width of2.664GB per second, DDR memory enables system OEMS to build high performance and low latency DRAM subsystems thatare suitable for servers, workstations, high-end PC's and value desktop SMA systems. Witha core voltage ofonly 2.5 volts compared to conventional SDRAM's 3.3 volts, DDR memory is a compelling solution for small form factor deskiops and notebook applications.

Whenever the BIOS detects a non-fatal error the system will be stopped. The system boot will not stop for a keyboard error, it will stop for all other errors. (Default value) The system boot will not stop for a disk error, it will stop for all oiher errors. The system boot will not stop for a keyboard or disk error, it will Stop for all other errors. The category is display-only which is determined by POST (Power On Self Test) ofthe BIOS. 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 te 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 CPU's memory address map.

This newest“Value-added" feature, in a long series ofinnovañons fom GIGABYTE, is available on GA-6OXET Series motherboard. Future GIGABYTE motherboards will also incorporate this innovation. What's DualBIOS""? On GIGABYTE motherboards w6ith DualBIOS there are physically two BIOS chips. For simplicity we’ll call one your ‘Main BIOS” and the other we’ call your “Backup” BIOS (your ‘hot spare”). ffyour Main BIOS fails, he Backup BIOS almost automatically takes over on your next system boot Almostautomañcally and with virually zero down me! Whether the problem is a failure in fashing your BIOS or a virus or a catastrophic failure ofthe Main BIOS chip, the result is he same - the Backup BIOS backs you up, almostautomañcally. -77- Technical Reference

1. Q: What is DualBIOS"" technology?

Answer: DualBIOS technology is a patented technology from Giga-Byte Technology. The conceptof this technology is based on the redundancy and fault tolerance theory. DualBIOS"" technology Simply means there are two system BIOSes (ROM) integrated onto the motherboard. One is a main BIOS, and the other is a backup BIOS. The mainboard will operate normally with the main BIOS, however, ifhe main BIOS is corrupt or damaged for various reasons, the backup BIOS will be automañcally used when the system powered-On. Your PC will operate as before the main BIOS was damaged, and is completely transparent to the user. Il. Q: Why does anyone need a motherboard with DualBIOS'" technology? Answer: In today/s systems there are more and more BIOS failures. The mostcommon reasons are virus attacks, BIOS upgrade failures, and/or deterioraton ofthe BIOS (ROM) chip itself. 1... New computer viruses are being found that attack and destroy the system BIOS. They may corrupt your BIOS code, causing your PC to be unstable or even notbootnormally.

2. BIOS data wil be corrupted ifa power loss/surge occurs, or ifa user resets the system,

orifthe power button is pressed during the process of performing a system BIOS upgrade.

3. la user mistakenly updates their mainboard with the incorrect BIOS fille, then the

system may notbe able to boot correctly. This may cause the PC system hang in operafon or during boot

4. Afash ROM' life cycle is limited according to electronic characteristics. The modern

PC uilizes the Plug and Play BIOS, and is updated regularly. fa user changes peripherals ofen, here is a slight chance of damage to the flash ROM. With Giga-Byte Technology's patented DualBIOST" technology you can reduce the possibiliy ofhangs during system boot up, and/or loss BIOS data due to above reasons. This new technology will eliminate valuable system down ime and costy repair bills cause by BIOS failures. KT400A Series Motherboard -78-

Ill. Q: How does DualBIOS'"" technology work? Answer:

DualBIOS" technology provides a wide range of protection during the boot up procedure. lt protects your BIOS during system POST, ESCD update, and even all the way to PNP detecton/assignment DualBIOS" provides automañc recovery for he BIOS. When the first BIOS used during bootup does notcomplete or ifa BIOS checksum error occurs, boot-up is still possible. In the DualBIOS"" utlity, he ‘Auto Recovery’ opion will guarantee that ifeither the main BIOS or backup BIOS is corrupted, the DualBIOS"" technology will use the good BIOS and correct he wrong BIOS automañcally. DualBIOS"" provides manual recovery for he BIOS. DualBIOS'" technology contains a builtin flash utlity, which can flash your system BIOS from backup to main and/or visa versa. There is no need for an OS-dependentflash utility program. DualBIOS"" contains a one-way flash utility. The built-in one-way fash utility will ensure thatthe corrupt BIOS is not mistaken as the good BIOS during recovery and thatthe correct BIOS (main vs. backup) will be flashed. This will preventthe good BIOS from being fashed.

Every user should have DualBIOS'" technology due to the advancementof computer viruses. Everyday, ere are new BlOS-type viruses discovered thatwill destroy your system BIOS. Most commercial products on the market do not have solutions to guard against this type ofvirus intrusion. The DualBIOST" technology will provide a state-ofthe-art solufon to protect your PC: Case 1) Vicious computer viruses may wipe out your entre system BIOS. With a convenfonal single system BIOS PC, the PC will notbe funcfonal unil it is sent for repaïrs. Case IL) f the ‘Auto Recovery" option is enabled in the DualBIOS" utlity, and ifa virus corrupts your system BIOS, the backup BIOS will automañially rebootthe system and correctthe main BIOS. Case IIL) À user may override boofng from the main system BIOS. The DualBIOSTM -79- Technical Reference

utlity may be entered to manually change the boot sequence to boot from the backup BIOS.

2. During or afer a BIOS upgrade, ifDualBIOS"" detects hat the main BIOS is corrupt the

backup BIOS will take over te boot-up process automañically. Moreover, itwill verify the main and backup BIOS checksums when bootng-up. DualBIOS"" technology examines the checksum ofthe main and backup BIOS while the system is powered on to guarantee your BIOS operates property.

3. Power Users will have the advantage ofhaving two BIOS versions on their mainboard.

Thebeneñtis being able t selecteither version BIOS to suitthe performance system needs.

4. Flexibility for high-end desktop PCs and workstaïon/servers. In the DualBIOST" uflity,

the option can be set, ‘Halt On When BIOS Defects,” to be enabled to halt your system with awarning message thatthe main BIOS has been corrupted. Most workstafion/servers require constant operafon to guarantee services have notbeen interrupted. In this situation, the ‘Halt On When BIOS Defects’ message may be disabled to avoid system pauses during normal booëng. Another advantage you gain from Giga-Byte's DualBlOST" technology is the ability to upgrade from dual 2 Mbit BIOS to dual 4 Mbit BIOS in the future ifextra BIOS storage is need.
