Suspend to RAM Installation

Suspend to RAM Installation

Suspend to RAM Installation
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 “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) “D:\setup /p j” in the window provided. Hit the enter key or click

OK. In Windows 98 second edition version, all the bios version dated 12/01/99 or
later are ACPI compatible. Just type" D:\Setup", the operating system will be installed

as ACPI mode.
C. After setup completes, remove the CD, and reboot your system
(This manual assumes that your CD-ROM device drive letter is D:).

Dual BIOS Introduction

Dual BIOS Introduction

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 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.

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-6CXC/6CXC-1 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 is 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 Backup BIOS backs you up, almost automatically.

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. DualBIOSTM 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, 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.

II. Q: Why does anyone need a motherboard with DualBIOSTM 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 ROM.

With Giga-Byte Technology’s patented DualBIOSTM 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.

6CXC/6CXC-1 Motherboard

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. DualBIOSTM 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 DualBIOSTM 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.

3. DualBIOSTM 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. DualBIOSTM 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 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 DualBIOSTM 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 II.) If the "Auto Recovery" option is enabled in the DualBIOSTM utility, and if a virus

corrupts your system BIOS, the backup BIOS will automatically reboot the system and

correct the main BIOS.
Case III.) A user may override booting from the main system BIOS. The DualBIOSTM utility
may be entered to manually change the boot sequence to boot from the backup BIOS.

Dual BIOS Introduction

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 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 DualBIOSTM utility, the
option can be set, "Halt On When BIOS Defects," to be enabled to halt your system with a
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.

•• Memory

The category is display-only which is determined by POST (Power On Self Test) of the
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 the motherboard.

Other Memory

This refers to the memory located in the 640 K to 1024 K address space. This
is memory that can be used for different applications.

DOS uses this area to load device drivers to keep as much base memory free
for application programs. Most use for this area is Shadow RAM.

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.

Appendix A : AU8810 Driver Installation

A. DRIVER INSTALLATION

If you have older drivers in your system, please uninstall them first as described in Section C
below.

1. Power on the system, placing the "Intel chipset Series Mainboard Utility CD" in the CD-ROM
drive.

2. During the load process, Windows 95/98 should detect the Vortex PCI board and display a
message such as "New Hardware Found". If Windows prompts you for the drivers of the "PCI
Multimedia Audio Device", then select "Driver Disk Provided by Manufacturer" Select the
Vortex CD-ROM's directory.

Note: Some Windows 95 versions (OSR2) do not show this prompt. Instead, they ask whether
to search the diskette and CD-ROM drives for the appropriate drivers.

Installed drivers may include Vortex PCI audio, Vortex wavetable, Vortex mixer, DOS modem
port, Vortex gameport interface, Vortex MPU401 interface, and Vortex Sound Blaster
emulation.

Depending on the version of Windows 95 and the configuration of the system, you may be
prompted to provide several file locations. Here are the CD-ROMs and directory locations for
which you may be prompted:

Vortex Installation & Driver Disk \aureal\win9X
Windows 95/98 Installation Disk \aureal\win9X
Microsoft DirectX \Utility\directx\dxsetup
Vortex Application Setup \aureal\win9X
PCI Multifunction Audio Device \aureal\win9X

B. UNINSTALLING WINDOWS 95/98 DRIVERS

To uninstall the Vortex software, you can use the following procedure:

1. Open to the Windows 95/98 Device Manager (right-click on "My Computer"
and select "Properties").

2. Open the "Multifunction Adapters" tree and select "Vortex
Multifunction PCI Platform"

3. Press the "Remove" button at the bottom of the Device Manager
window pane.

4. The drivers are now removed from memory, but are still on the hard
disk. To delete the files from the hard disk:

a. Open the Windows 95/98 control panel's "Add/Remove Programs"
applet.

b. To remove the drivers, double-click "Aureal Vortex". A
Vortex uninstaller application starts.

c. To remove the demo applications, double-click "Aureal
