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 (Th is 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

open STR Disabled

close STR Enabled

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

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 Dow n”

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

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.

Suspend To RAM Installation

6CX Motherboard

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.

5. Use the “Modem Ring On” function.

6. Use the “Wake On LAN” function.

7. Use the “USB Device Wake up” function.

Suspend To RAM Installation

A.5 Notices :

1. In order for STR to function properly, several hardware and software requirements must be

satisfied:

A. Your ATX power supply must comply with the ATX 2.01 specification (provide more than 720

mA 5V Stand-By current).

B. Your SDRAM must be PC-100 compliant.

2. Jumper JP2 is provided to connect to the STR LED in your system chassis. [Your chassis may not provide this feature.] The STR LED will be illuminated when your system is in STR sleep mode.

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.

B. How to use Dual BIOS?

Dual BIOS Introduction

Wide Range Protection: Disable(Default), Enable

Status 1:

If any failure (ex. Update ESCD failure, checksum error or reset…) occurs in the Main

BIOS , just before the Operating System is loaded and after the power is on, and that the Wide Range Protection is set to “Enable”, the PC will boot from Backup BIOS automatically.

Status 2:

If the ROM BIOS on peripherals cards(ex. SCSI Cards, LAN Cards,..) emits signals to

request restart of the system after the user make any alteration on it, the boot up BIOS will not be changed to the Backup BIOS.

6CX Motherboard

Boot From : Main BIOS (Default), Backup BIOS

Status 1:

The user can set to boot from main BIOS or Backup BIOS.

Auto Recovery : Enabled(Default), Disabled

When one of the Main BIOS or Backup BIOS occurs checksum failure, the working BIOS will

automatically recover the BIOS of checksum failure. (In the Power Management Setup of the BIOS Setting, if ACPI Suspend Type is set to Suspend

to RAM, the Auto Recovery will be set to Enable automatically.)

Dual BIOS Introduction

DualBIOS

GIGABYTE Technology is pleased to introduce DualBIOS technology, a hot spare for your system BIOS. This new ness “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 automati cally.

Technology FAQ

6CX Motherboard

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

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 bac kup BIOS.

6CX Motherboard

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 booti ng. 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

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.

Install memory in any combination table:

RIMM 1 RIMM 2

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.

Extended Memory

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.

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

For Technical Support please contact your board manufacturer.
