Installation Guide Installation Guide Getting Started WARNING! Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To protect them against damage from static electricity, you should follow some precautions whenever you work on your computer. 1 Unplug your computer when working on the inside.

2. Use a grounded wrist strap before handling computer components. If you do not have one,

touch both of your hands to a safely grounded object or to a metal object, such as the power supply case.

3. Hold components by the edges and try not touch the IC chips, leads or connectors, or

4. Place components on a grounded antistatic pad or on the bag that came with the

components whenever the components are separated from the system.

5. Ensure thatthe ATX power supply is switched off before you plug in or remove the ATX

power connector on the motherboard. Installing the motherboard to the chassis. Ifthe motherboard has mounting holes, but they don't line up with the holes on the base and there are no slots to attach the spacers, do not become alarmed you can still attach the spacers to the mounting holes. | ust cutthe bottom portion ofthe spacers (the spacer may be a little hard to cutoff, so be careful of your hands). In this way you can still attach the motherboard to the base without worrying about short circuits. Sometimes you may need to use the plastic springs to isolate the screw from the motherboard PCB surface, because the circuit wire may be near by the hole. Be careful, don't letthe screw contact any printed circuit write or parts on the PCB that are near the fixing hole, otherwise it may damage the board or cause board malfunctioning.

DDR Introduction Established on the existing SDRAM industry infrastructure, DDR (Double Data Rate) memory is a high performance and cost-effective 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 solving the system performance bottleneck by doubling the memory bandwidth. DDR SDRAM will offer a superior solution and migration path from existing SDRAM designs due to its availability, pricing and overall market support. PC2100 DDR memory (DDR266) doubles the data rate through reading and writing at both the rising and falling edge of the clock, achieving data bandwidth 2X greater than PC133 when running with the same DRAM clock frequency. With peak bandwidth of 2.1GB per second, DDR memory enables system OEMS to build high performance and low latency DRAM subsystems that are suitable for servers, workstations, high-end PC's and value desktop SMA systems. With a core voltage of only 2.5 Volts compared to conventional SDRAM's 3.3 volts, DDR memory is a compelling solution for small form factor desktops and notebook applications.

Suspend to RAM Installation Suspend To RAM Installatio A.1 Introduce STR function: Suspend-to-RAM (STR) is a Windows 98 ACPI sleep mode function. When recovering from STR (S3) sleep mode, the system is able, in just a few seconds, to retrieve the last “state” of the system before it went to sleep and recover to that state. The “state” is stored in memory (RAM) before the system goes to sleep. During STR sleep mode, your system uses only enough energy to maintain critical information and system functions, primarily the system state and the ability to recognize various ‘ivake up”triggers or signals, respectively. A.2 STR function Installation Please use the following steps to complete the STR function installation Step-By-Step Setup Step 1: To utilize the STR function, the system must be in Windows 98 ACPI mode. Putting Windows 98 into ACPI mode is fairly easy. Setup with Windows 98 CD: A Insertthe Windows 98 CD into your CD-ROM drive, select Start, and then Run.

What is Dual BIOS Technology? Dual BIOS means that there are two system BIOS (ROM) on the motherboard, one is the Main BIOS and the other is Backup BIOS. Under the normal circumstances, the system works on the Main BIOS. Ifthe Main BIOS is corrupted or damaged, the Backup BIOS can take over while the system is powered on. This means that your PC will still be able to run stably as if nothing has happened in your BIOS How to use Dual BIOS? a.

JDXR Motherboard TM DualBIOS'" Technology FAQ GIGABYTE Technology is pleased to introduce DualBIOS technology, a hot spare for your system BIOS. This newest Value-added” feature, in a long series of innovations from GIGABYTE, is available on GA-7DXR motherboard. Future GIGABYTE motherboards will also incorporate this innovation. What's DualB10ST1? On GIGABYTE motherboards with DualBlOS there are physically two BIOS chips. For simplicity well call one your ‘Main BIOS "and the other we‘! call your “Backup” BIOS (your “hot spare”). If your Main BIOS fails, the Backup BIOS almost automatically takes over on your nextsystem boot. Almost automatically and with virtually zero down time! Whether the problem is a failure in flashing your BIOS or a virus or a catastrophic failure of the Main BIOS chip, the result is the same - the Backup BIOS backs you up, almost automatically.

1. Q: What is DualBIOST" technology?

Answer: DualBIOS technology is a patented technology from Giga-Byte Technology. The concept of this technology is based on the redundancy and fault tolerance theory. DualBIOST" 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, ifthe main BIOS is corrupt or damaged for various reasons, the backup BIOS will be automatically 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 DualBIOST" technology? Answer: In today's systems there are more and more BIOS failures. The most common reasons are virus attacks, BIOS upgrade failures, and/or deterioration ofthe BIOS (ROM) chip itself. 1 New computer viruses are being found that attack and destroy the system BIOS. They may corupt your BIOS code, causing your PC to be unstable or even not boot normally.

2. BIOS data will be corrupted if a power loss/surge occurs, or if a user resets the system, or

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

3. fa user mistakenly updates their mainboard with the incorrect BIOS file, then the system

may not be able to boot correctly. This may cause the PC system hang in operation or during boot.

4. Aflash ROM'S life cycle is limited according to electronic characteristics, The modern PC

utilizes the Plug and Play BIOS, and is updated regularly. If a user changes peripherals often, there is a slight chance of damage to the flash ROM With Giga-Byte Technology's patented DualBlOST" technology you can reduce the possibility of hangs during system boot up, and/or loss BIOS data due to above reasons. This new technology will eliminate valuable system down time and costly repair bills cause by BIOS failures.

7DXR Motherboard Ill, Q: How does DualBIOST" technology work? Answer:

DualBIOST" technology provides a wide range of protection during the boot up procedure. It protects your BIOS during system POST, ESCD update, and even all the way to PNP detection/assignment. … DualBIOST" provides automatic recovery for the BIOS. When the first BIOS used during boot up does not complete or if a BIOS checksum error occurs, boot-up is still possible. In the DualBIOST" utility, the "Auto Recovery" option will guarantee that if either the main BIOS or backup BIOS is corrupted, the DualBIOSTM technology will use the good BIOS and correct the wrong BIOS automatically. .… DualBIOST" provides manual recovery for the BIOS. DualBIOST" technology contains a built-in flash utility, which can flash your system BIOS from backup to main and/or visa versa There is no need for an OS-dependent flash utility program. . DualBIOST" contains à one-way flash utility. The built-in one-way flash utility will ensure that the corrupt BIOS is not mistaken as the good BIOS during recovery and that the correct BIOS (main vs. backup) will be flashed. This will prevent the good BIOS from being flashed.

Every user should have DualBIOSTM technology due to the advancement of computer viruses Everyday, there are new BIOS-type viruses discovered that will destroy your system BIOS Most commercial products on the market do not have solutions to guard against this type of virus intrusion. The DualBIOST" technology will provide a state-of-the-art solution to protect your PC: Case I.) Vicious computer viruses may wipe out your entire system BIOS. With a conventional single system BIOS PC, the PC will not be functional until it is sent for repairs. Case Il.) Ifthe "Auto Recovery" option is enabled in the DualBIOST" utility, and if a virus corrupts your system BIOS, the backup BIOS will automatically reboot the system and correctthe main BIOS. Case Ill.) À user may override booting from the main system BIOS. The DualBIOST" utility may be entered to manually change the boot sequence to boot from the backup BIOS.

2. During or after a BIOS upgrade, if DualBIOSTM detects that the main BIOS is corrupt, the

backup BIOS will take over the boot-up process automatically. Moreover, it will verify the main and backup BIOS checksums when booting-up. DualBIOSTM technology examines the checksum ofthe main and backup BIOS while the system is powered on to guarantee your BIOS operates properly. Power Users will have the advantage of having two BIOS versions on their mainboard. The benefit is being able to select either version BIOS to suit the performance system needs.

4. Flexibility for high-end desktop PCs and workstation/servers. In the DualBIOSTM utility,

the option can be set, "Halt On When BIOS Defects," to be enabled to halt your system with à warning message that the main BIOS has been corrupted. Most workstation/servers require constant operation to guarantee services have not been interrupted. In this situation, the "Halt On When BIOS Defects" message may be disabled to avoid system pauses during normal booting. Another advantage you gain from Giga-Byte's DualBIOSTM technology is the ability to upgrade from dual 2 Mbit BIOS to dual 4 Mbit BIOS in the future if extra BIOS storage is need.

EasyTunellf M Introduction syTunelll” Introduction Gigabyte announces EasyTunelll"” Windows overdrive utility “Overdrive" might be one of the most common issues in computer field. But have many users ever tried it? The answer is probably “no”. Because ‘overdrive” is thought to be very difficult and includes à lot of technical know-how, sometimes ‘overdrive” is even considered as special skills found only in some enthusiasts. But as to the experts in ‘overdrive”, what's the truth? They may spend quite à lot of time and money to study, try and use many different hardware and software tools to do “overdrive”. And even with these technologies, they still learn that its quite a risk because the safety and stability of an “overdrive" system is unknown. Now everything is different because of a Windows overdrive utility EasyTunelIl” --announced by Gigabyte. This utility has totally changed the gaming rule of “overdrive”. This is the first overdrive utility suitable for both normal and power users. Users can choose either ‘Easy Mode” or ‘Advanced Mode” to run ‘overdrive” at their convenience. For users who choose “Easy Mode”, they just need to click “Auto Optimize" to have auto and immediate CPU overclocking. This software will then overdrive CPU speed automatically with the result being shown in the control panel. If someone prefers to “overdrive” by oneself, there is also another choice. Click ‘Advanced Mode” to enjoy “sport drive” class overclocking. In “Advanced Mode”, one can change the system bus speed in small increments to get ultimate system performance. And no matter which mainboard is used, ifits a Gigabyte's product*, EasyTunelIl” helps to perform the best of system. Besides, different from other traditional over-clocking methods, EasyTuneIIl" doesn't require users to change neither BIOS nor hardware switch/ jumper setting; on the other hand, they can do “overdrive” at only one click. Therefore, this is a safer way for ‘overdrive" as nothing is changed on software or hardware. If user runs EasyTunelIl” over systems limitation, the biggest lost is only to restart the computer again and the side effect is then well controlled. Moreover, if one well-performed system speed been tested in EasyTunelll”, user can “Save” this bus speed and “Load” it in next time. Obviously, Gigabyte EasyTuneIIl” has already tumed the “overdrive” technology toward to à newer generation.

7DXR Motherboard This wonderful software is now free bundled in Gigabyte motherboard attached driver CD. Users may make a test drive of"EasyTuneIIT ” "to find out more amazing features by themselves.

Raid Introduction Raid Intro: What is RAID? tion This motherboard implements two different types of RAID levels as follows: RAID 0 (stripe) For capacity -- The motherboard array will be as big as the smallest HDD in the array times however many HDDs are in the array. Any larger HDDs will simply be truncated. The truncated space on the bigger HDDs will then be unusable. For sustained data transfers -- A RAID 0 array consisting of two HDDs will transfer at about twice the speed of the slowest HDD in the array. À RAID 0 array consisting of four HDDs will transfer at about three times the speed of the slowest HDD in the array. RAID 1 (mirror) For capacity - This Motherboard array will be as big as the smallest HDD in the array. The larger HDD will simply be truncated. The truncated space on the bigger HDD will then be unusable. For sustained data transfers -- This motherboard array will write data at the rate of the slowest HDD in the array. This motherboard array will read data at twice the rate of the slowest HDD in the array.

7DXR Motherboard About RAID Levels Striping (RAID 0) Reads and writes sectors of data interleaved between multiple drives. When any disk member fails, it affects the entire array. Performance is better than a single drive since the workload is balanced between the array members. This array type is for high performance systems. Identical drives are recommended for performance as well as data storage efficiency. The disk array data capacity is equal to the number of drive members times the smallest member capacity. For example, one 1GB and 1 drives will form a 2GB (2 x 1GB) disk array. Stripe Size - a value can be set from 1KB to 1024KB sector size. The size can directly affect performance. Inthe FastBuild BIOS, the Desktop" defaultis 8KB while “Server” and ‘AV Editing”are 64KB. Data Blocks RAID 0 (Striping)

Raid Introduction Mirroring (RAID 1) Writes duplicate data on to a pair of drives while reads are performed in parallel. ATA RAID 1 is fault tolerant because each drive of a mirrored pair is installed on separate IDE channels. lfone ofthe mirrored drives suffers à mechanical failure (e.g. spindle failure) or does not respond, the remaining drive will continue to function. This is called Faut Tolerance lf one drive has à physical sector error, the mirrored drive will continue to function

RAID 1 (Mirroring) On the next reboot, the FastBuildT M utility will display an error in the array and recommend to replace the failed drive. Users may choose to continue using their PC, however Promise recommends replacing the failed drive as soon as possible. See Chapter 4 for a functional description Due to redundancy, the drive capacity oftthe array is half the total drive capacity. For example, two 1GB drives that have a combined capacity of 2GB would have 1GB of usable storage. With drives of different capacities, there may be unused capacity on the larger drive.

7DXR Motherboard Creating Your Disk Array You will now use the FastBuild BIOS utility to create your array using the attached drives. There are two different scenarios in creating this array. You can create an array for performance, you can create a Security array using new hard drives (recommended).

7DXR Motherboard How Orders Arrays During startup, the disk arrays on the motherboard are recognized in this order: 1) The array set to bootable in the FastBuild? M Setup, and 2) the Array number (i.e. Array 0, Array 1...) This would be involved in determining which drive letters will be assigned to each disk array. How Saves Array Information All disk array data is saved into the reserved sector on each array member. We suggests that users record their disk array information for future reference. Another feature of the motherboard disk array system is to recognize drive members even if drives are moved between different motherboard connectors(IDE 3&IDE4). Since each drive's array data identifies itself to the array, itis possible to move or swap drives without modifying the array setup. This is valuable when adding drives, or during a rebuild

Raid Introduction Deleting An Array The Delete Array <4> Menu option allows for deletion of disk array assignments. This is notthe same as deleting data from the drives themselves. If you delete an array by accident (and before it has been used again), the array can normally be recovered by defining the array identically as the deleted array.
