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:).

Suspend To RAM Installation

Step 2:

(If you want to use STR Function, please set jumper JP1 (Closed.)

JP1 : STR Enable

Step 3:

Power on the computer and as soon as memory counting starts, press <Del>. You will enter BIOS
Setup. Select the item “POWER MANAGEMENT SETUP”, then select “ACPI Sleep Type: S3
/STR”. Remember to save the settings by pressing "ESC" and choose the “SAVE & EXIT SETUP”
option.

Congratulation! You have completed the installation and now can use the STR function.

6CX Motherboard

31

A.3 How to put your system into STR mode?

There are two ways to accomplish this:

1. Choose the “Stand by” item in the “Shut Down Windows” area.

A. Press the “Start” button and then select “Shut Down”

B. Choose the “Stand by” item and press “OK”

Suspend To RAM Installation

32

2. Define the system ”power on” button to initiate STR sleep mode:

A. Double click “My Computer” and then “Control Panel”

B. Double click the “ Power Management” item.

6CX Motherboard

33

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

Step 4:

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 seven ways to “wake up” the system:

1. Press the “Power On” button.

2. Use the “Keyboard Power On” function.

3. Use the “Mouse Power On” function.

4. Use the “Resume by Alarm” function.

Dual BIOS Introduction

Introduce Dual BIOS

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 newness “Value-added” feature, in a long series of innovations from GIGABYTE, is
available on GA-6CX 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 Backup BIOS backs
you up, almost automatically.

6CX Motherboard

39

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 syst ems 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.

Dual BIOS Introduction

40

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.

6CX Motherboard

41

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 Installation

Memory Installation

The motherboard has Rambus In-line Memory Module (RIMM) sockets. The BIOS will automatically
detects memory type and size. To install the memory module, just push it vertically into the RIMM
Slot .The RIMM module can only fit in one direction due to the two notch. Memory size can vary
between sockets.

⇒ Configurable optional ECC operation

Ÿ ECC with single bit Error Correction and multiple bit Error Detection
Ÿ Single bit errors corrected and written back to memory (auto-scrubbing)
Ÿ Parity mode not supported

DRAM Interface

The MCH supports a single channel of Direct RDRAM memory using RSL technology. 300 and
400MHz Direct RDRAM devices are supported. 64, 128 and 256Mb technology Direct RDRAM
devices are supported. A maximum of 32 Direct RDRAM devices (64Mb technology = 256MB max)
are supported for a single channel. The following table shows the maximum DRAM array size and the
minimum increment size for the various DRAM densities supported for MCH.

RDRAM Technology Increments Maximum

64Mb/72Mb 8MB 256MB
128Mb/144Mb 16MB 512MB
256Mb/288Mb 32MB 1GB

The MCH provides optional ECC error checking for DRAM data integrity. During DRAM writes ECC
is generated on a QWORD (64bit) basis. Partial QWORD writes require a read-modify-write cycle when
ECC is enabled. During DRAM reads, the MCH supports detection of single-bit and multiple-bit errors,
and will correct single bit errors when correction is enabled. The MCH will automatically scrub single bit
errors by writing the corrected value back into DRAM when scrubbing is enabled. ECC can only be
enabled when the Direct RDRAMs support the extra two data bits used to store the ECC code.

The MCH provides a maximum DRAM address decode space of 4GB. The MCH does not remap
APIC memory space in hardware. It is the BIOS or system designers responsibility to limit DRAM
population so that adequate PCI, AGP, High BIOS, and APIC memory space can be allocated.

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

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").

Appendix

78

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
Vortex Applications". There is no need to reboot the computer.
