$A$ Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and other components. Always observe the following precautions before you install a system component. 1.Do not remove a component from its protective packaging until you are ready to install it. 2.Wear a wrist ground strap and attach it to a metal part of the system unit before handling a component. If a wrist strap is not available, maintain contact with the system unit throughout any procedure requiring ESD protection.

You have to wait for system to successfully boot from operation system (such as Windows or DOS) before the Wake-On-Keyboard/Mouse can take effect. This is because the information of how to support this function must be stored into Super I/O Controller and then you can use it for next power on.

$$

The driving capability of new generation chipset is limited due to the lack of a memory buffer (to improve performance). This makes DRAM chip count an important factor to take into consideration when you install DIMMs. Unfortunately, there is no way that the BIOS can identify the correct chip count, you need to calculate the chip count by yourself. The simple rule is: !"##$%%%%.
To identify 2-clock and 4-clock DIMM, you may check if there are traces connected to the golden finger pins 79 and 163 of the SDRAM. If there are traces, the SDRAM is probably 4-clock; otherwise, it is 2-clock.

@&'2# 0'+

To identify single-side or double-side DIMM, check golden finger pin 114 and pin 129. If there are traces connected to pin 114 and pin 129, the DIMM is probably double-side; otherwise, it is single-side.

The upgrade of new BIOS will permanently replace your original BIOS content after flashing. The original BIOS setting and Win95/Win98 PnP information will be refreshed and you probably need to re-configure your system.
If you prefer to use EPROM writer, you can find BIOS BIN file after unzip.

CPU Jumper-less Design

CPU VID signal and SMbus clock generator provide CPU voltage auto-detection and allows the user to set the CPU frequency through the BIOS setup, therefore no jumpers or switches are used. The correct CPU information is saved into the EEPROM. With these technologies, the disadvantages of the Pentium based jumper-less designs are eliminated. There will be no worry of wrong CPU voltage detection and no need to re-open the housing in case of CMOS battery loss. Clock Generator Pentium II/III & Celeron CPU CPU Freq. Ratio CPU VID Signal CPU voltage Power Regulator (Automatically generates CPU voltage) Controlled Circuit

Setting CPU Core Voltage

This motherboard supports CPU VID function. The CPU core voltage will be automatically detected and the range is from 1.3V to 3.5V.

Setting CPU Frequency

This motherboard is CPU jumper-less design, you can set CPU frequency through the BIOS setup, no jumpers or switches are needed.
BIOS Setup > Frequency Control > CPU Speed Setting
Warning: INTEL 810/810E chipsets supports maximum 100MHz or 133MHz FSB and 66MHz AGP clock, higher clock setting may cause serious system damage. Tip: If your system hangs or fails to boot because of overclocking, simply use JP14 to clear CMOS and restore to the default setting (350MHz when FSB=100MHz; 267MHz when FSB=133.3MHz ).
Core Frequency = CPU FSB Clock * CPU Ratio

Note: The maximum FSB clock is different on different models of MX3W Pro series. Please refer to Models of MX3W Pro Series for detail.
JP23/JP29 AGP/FSB Clock Ratio (Turbo AGP)
To improve system performance, this motherboard has implemented this jumper for setting the ratio of the display cache and CPU external frequency. Auto: No matter what the CPU type is, the onboard display cache will be set automatically. We recommend that you remain this default setting. 1/1: The display cache runs at a speed as same as the CPU external clock. 3/2: The display cache runs at a speed of 3/2 CPU external clock.

DIMM Socket

This motherboard has two 168-pin DIMM sockets that allow you to install PC100 memory up to 512MB. Only SDRAM is supported.

Pin 1 DIMM1 DIMM2

Tip: The driving capability of new generation chipset is limited due to the lack of a memory buffer (to improve performance). This makes DRAM chip count an important factor to take into consideration when you install DIMMs. Unfortunately, there is no way that the BIOS can identify the correct chip count, you need to calculate the chip count by yourself. The simple rule is: By visual inspection, use only DIMMs which are less than 16 chips.

Warning: The specification of the IDE cable is a maximum of 46cm (18 inches), make sure your cable does not exceed this length. Tip: For better signal quality, it is recommended to set the far end side device to master mode and follow the suggested sequence to install your new device. Please refer to above diagram.
This motherboard supports ATA/66 IDE. Following table lists the transfer rate of IDE PIO and DMA modes. The IDE bus is 16-bit, which means every transfer is two bytes.

Tip: To achieve the best performance of Ultra DMA/66 hard disks, a special 80-wires IDE cable is required.

IrDA Connector

The IrDA connector can be configured to support wireless infrared module, with this module and application software such as Laplink or Windows 95 Direct Cable Connection, the user can transfer files to or from laptops, notebooks, PDA devices and printers. This connector supports SIR (115.2Kbps, 2 meters) and ASK-IR (57.6Kbps). Install the infrared module onto the IrDA connector and enable the infrared function from BIOS Setup > Integrated Peripherals > UART Mode Select, make sure to have the correct orientation when you plug in the IrDA connector.

WOM by Internal Modem Card
With the help of the ATX soft power On/Off, it is possible to have a system totally power off, and wakeup to automatically answer a phone call as an answering machine or to send/receive a fax. You may identify whether or not your system is in true power off mode by checking to see if the fan of your power supply is off. Both an external box modem and an internal modem card can be used to support Modem Wake Up, but if you use an external modem, you have to leave your box modem on.

Modem Card TEL Line

With AOpen Motherboard plus AOpen Modem Card, the power can be totally off. Motherboard

WOL (Wake on LAN)

This feature is very similar as Wake On Modem, but it goes through local area network. To use Wake On LAN function, you must have a network card with chipset that supports this feature, and connect a cable from LAN card to motherboard WOL connector. The system identification information (probably IP address) is stored on network card and because there is a lot of traffic on the Ethernet, you need to install a network management software, such as ADM, for the checking of how to wake up the system. Note that, at least 600mA ATX standby current is required to support the LAN card for this function.

2X AGP (Accelerated Graphic Port)
This motherboard supports 2X AGP on Chip, you dont need to have AGP VGA card. AGP is a bus interface designed for high-performance 3D graphic and supports only memory read/write operation. One motherboard can only have one AGP slot. 2X AGP uses both rising and falling edge of the 66MHz clock, the data transfer rate is 66MHz x 4 bytes x 2 = 528MB/s.

It is necessary to install Bus Master IDE driver to support ATA/66 hard disk. If you need this driver, you can find it in the AOpen Bonus Pack CD disc.
Note: Installing this Bus Master IDE driver may cause Suspend to Hard Drive failure.
Installing Hardware Monitoring Utility
You can install Hardware Monitoring Utility to monitor CPU temperature, fans and system voltage. You can find it in the AOpen Bonus Pack CD disc.
ACPI Suspend to Hard Drive
ACPI Suspend to Hard Drive is basically controlled by Windows operation system. It saves your current work (system status, memory and screen image) into hard disk, and then the system can be totally power off. Next time, when power is on, you can resume your original work directly from hard disk within few seconds without go through the Windows booting process and run your application again. If your memory is 64MB, normally, you need to reserve at least 64MB HDD space to save your memory image.

The PNP/PCI Configuration Setup allows you to configure the ISA and PCI devices installed in your system. The following screen appears if you select the option "PNP/PCI Configuration Setup" from the main menu.
PNP/PCI Configuration > Reset Configuration Data

-! "

In case conflict occurs after you assign the IRQs or after you configure your system, you can enable this function, allow your system to automatically reset your configuration and reassign the IRQs, DMAs, and I/O address.

Save & Exit Setup

This function automatically saves all CMOS values before leaving Setup.

Exit without Saving

Do not use this option if
Use this function to exit Setup without saving the CMOS value changes. you want to save the new configuration.

Load EEPROM Default

Except "Load Setup Default" and "Load Turbo Default", you may also use "Save EEPROM Default " to save your own settings into EEPROM, and reload by using this item.

Save EEPROM Default

You may use this item to save your own settings into EEPROM. Then, if the data in CMOS is lost or you forget the previous settings, you may use "Load EEPROM Default " to reload.
NCR SCSI BIOS and Drivers
Due to Flash ROM space limitation, some BIOS versions do not include NCR 53C810 SCSI BIOS (supports DOS, Windows 3.1 and OS/2) into the system BIOS. Many SCSI cards have its own SCSI BIOS on card, for better system performance, you may use the drivers that come with the NCR SCSI card or with your operating system. For details, refer to the installation manual of your NCR 53C810 SCSI card.

BIOS Upgrade

AOpen Easy Flash is a little different than traditional flash method. The BIOS binary file and flash routine are linked together and you simply run a single commend to complete the flash process.
1. Download new BIOS upgrade zipped file from AOpen's web site. For example, AX6C100.ZIP. 2. Unzip it and we recommend to save into a bootable DOS floppy diskette for error recovery. 3. Reboot the system to DOS mode without loading any memory handler (such as EMM386) or device driver. It needs around 520K free memory space. 4. Execute A:> AX6BC100
DO NOT turn off the power during FLASH PROCESS.
5. Reboot system and press <Del> to enter BIOS setup, Choose "Load Setup Defaults", then Save & Exit Setup. Done!
Warning: The upgrade of new BIOS will permanently replace your original BIOS content after flashing. The original BIOS setting and Win95/Win98 PnP information will be refreshed and you probably need to re-configure your system.
Tip: If you prefer to use EPROM writer, you can find BIOS BIN file after unzip.

Glossary

Basically, AC97 specification separates sound/modem circuit to two parts, digital processor and a CDDEC for analog I/O, they are linked by AC97 link bus. Since digital processor can be put into motherboard main chipset, the cost of sound/modem onboard solution can be reduced.
ACPI (Advanced Configuration & Power Interface)
ACPI is the power management specification of PC97 (1997). It intends to save more power by taking full control of power management to operating system and bypass BIOS. The chipset or super I/O chip needs to provide standard register interface to operating system (such as Windows 98). This is a bit similar as the PnP register interface. ACPI defines ATX momentary soft power switch to control the power state transition.
