Suspend To RAM Installation

Suspend to RAM Installat i on

A.1 Introduce STR function:

Suspend-to-RAM (STR) is a Wi ndows 98 ACPI sleep mode functi on. When recovering from

STR (S3) sleep mode, the system is able, in just a few seconds, to r etrieve 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 “wake 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. Insert the Windows 98 CD into your CD-ROM drive, select Start, and then Run.
B. Type (without quotes)
C. After setup completes, remove the CD, and reboot your system
(This manual assumes that your CD-ROM device drive letter is D:).

“D:\setup”

in the window provided. Hit the enter key or click OK.

B. Double click the “ Power Management” item.

27

Suspend to RAM Installat i on

C. Select the “Advanced” tab and “Standby” mode in Power Buttons.

D. Restart your computer to complete setup.
Now when you want to enter STR sleep mode, just momentarily press the “Power on”

button.

A.4 How to recover from the STR sleep mode?

There are five ways to “wake up” the system:

1. Press the “Power On” button.

2. Use the “Resume by Alarm” function.

3. Use the “Modem Ring On” function.

4. Use the “Wake On LAN” function.

5. Use the “USB Device Wake Up” function.

28

7ZX Series Motherboard

A.5 Notices:

1. In order for STR to function properly, several ha rdware and softwa re requirements must

be satisfied:

Dual BIOS Introduction

Dual BIOS Introduction (Optional)

A. 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. If the Mai n BIOS is corrupt ed or damaged, the Backup BIOS c an
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.

7ZX Series Motherboard

GIGABYTE Technology is pleased to introduce DualBIOS technology, a hot spare for your
system BIOS. This newness “Value-added” feature, in a long series of innovations from
GIGABYTE, is available on GA-7ZX Series motherboard. Future GIGABYTE motherboards will
also incorporate this innovation.

What’s DualBIOSTM?

On GIGABYTE motherboards with DualBIOS there are physically two BIOS chips. For
simplicity we’ll call one your “Main BIOS” and the other we’ll call your “Backup” BIOS (your “hot
spare”). If your Main BIOS fails, the Backup BIOS almost automatically takes over on your
next system 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 Ba ckup BIOS backs you up, almost automatically.

DualBIOSTM Technology FAQ

33

Dual BIOS Introduction

I. Q: What is DualBIOSTM 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. DualBIOS
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, if the 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.

TM

technology

II. Q: Why does anyone need a motherboard with DualBIOS

TM

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 of the 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 not boot normally.

2. BIOS data will be corrupted if a power loss/surge occurs, or if a user resets the system, or
if the power button is pressed during the process of performing a system BIOS upgrade.

3. If a 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. A flash 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

technology will eliminate valuable system down time and costly repair bills cause by BIOS
failures.

III. Q: How does DualBIOSTM technology work?
Answer:

1. DualBIOSTM 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.

2. DualBIOS

TM

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

TM

provides manual recovery for the BIOS. DualBIOSTM 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.

4. DualBIOS

TM

contains a 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.

IV. Q: Who Needs DualBIOSTM technology?
Answer:

1. Every user should have DualBIOSTM technology due to the advancement of computer
viruses.
Everyday, there are new BIOS-type viruses discovered t hat will destroy your system BIOS.
Most commercial products on the market do not have solutions to guard against this type of
virus intrusion. The DualBIOS
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 II.) If the "Auto Recovery" option is enable in the DualBIOS
corrupts your system BIOS,
correct the main BIOS.
Case III.) A user may override booting from the main system BIOS. The DualBIOS
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. DualBIOS
checksum of the main and backup BIOS while the system is powered on to guarantee your
BIOS operates properly.

3. 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 DualBIOS

option can be set, "Halt On When BIOS Defects," to be enable to halt your system with a
warning message that the main BIOS has be en 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 disable to avoid system pauses during normal
booting. Another advantage you gai n from Giga-Byte’s DualBIOS

Windows overdrive utilit y

“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 a 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 a 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 it’s quite a
risk because the safety and stability of an “overdrive“ system is unknown.

Now everything is different because of a Windows overdrive utility
EasyTune

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, if it’s a Gigabyte’s

product*, EasyTune

Besides, different from other traditional over-clocking methods, EasyTune
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
