Overview

AX3L is a new generation Socket 370 based system board that utilizes Intel 82440LX AGPset onATX PCI/ISA platform. This AGPset is designed for Pentium II CPU, and supports new architectures such as high speedAGP graphic port,SDRAM,Ultra DMA/33,Bus master IDE andUSB port. It hasthree Dual in-line Memory Module (DIMM) that allow to install SDRAM memory and expand up to a maximum of768MB. Since the cache is on the

Pentium II CPU card (connector SLOT1), there is no second level cache onboard Also, AX3L uses 2M bit Flash ROMBIOS to reserve for future new functions.

Not only above features, AX3L also implements many special features as following.

Jumper-less Design Celeron PPGA VID signal and SMbus clock generator provide CPU voltageauto-detectionand allows user to set CPU frequency through CMOS setup, no jumper or switch is needed. The correct CPU information is saved into EEPROM, with these technologies, the disadvantages of Pentium basejumper-lessdesign are eliminated. There will be no worry of wrong CPU voltage detection and no need tore-openthe housing if CMOS battery loss. The only jumper left is to clear CMOS, which is a safety hook if you forget the password.

Battery-less AX3L implements EEPROM and special circuit (patent applied) that allows you to save your current CPU and CMOS Setup configurations without the need of battery. The RTC (real time clock) can also keep running as long as power cord is plugged. If you lose your CMOS data by accident, you can just reload the CMOS configurations from EEPROM and the system will recover as usual.

APM Suspend To Hard Drive "Immediately" turns on system and goes back to the original screen before power down. You can resume your original work directly from hard disk without go through the Win95 booting process and run your application again. Suspend to Hard Drive saves your current work (system status, memory image) into hard disk. Note that you have to use

Overview

VESA compatible PCI VGA, Sound Blaster compatible sound card with APM driver, for Suspend to Hard Drive to work properly.

Zero Voltage Wake on Modem In conjunction with ATX soft power On/Off, it is possible to have system totally power off and wakeup to automatically answer a phone call such as answering machine or to send/receive fax. The most important break through is not only external box modem but also internal modem card can be used to support Wake On Modem. The AX3L and MP56 internal modem card implement special circuit (patent applied) to make sure the modem card work properly without any power.

Wake on LAN This feature is very similar as Wake On Modem, but it is through local area network. To use Wake on LAN function, you must have a network card that supports this feature and also need to install a network management software.

Wake on RTC Timer The Wake Up Timer is more like an alarm, which wakes up and power on your system at apre-definedtime for specific application. It can be set to wake up everyday or on specific date within a month. The date/time accuracy is second.

Wake on Keyboard This feature allows you power on your system by clicking the hot key that you specified. Besides, you also may disable the function of power button and let the system can only be powered on through the preset keys (like a password).

Wake on Mouse This function allows you wake up the system by clicking mouse button twice successively.

AC Power Auto Recovery A traditional ATX system should remain at power off stage when AC power resumes from power failure. This design is inconvenient for a network server or workstation, without an UPS, that needs to keeppower-on.This motherboard implements an AC Power Auto Recovery function to solve this problem. In BIOS Setup setting the item to Enabled lets the system can automaticallypower-onafter AC power resumes.

High Efficient Synchronous Switching Regulator Most of the current switching designs are Asynchronous mode, which from the technical point of view, still consumes very high power as well as heat. AX3L implements high efficient synchronous switching design that the temperature of MOS FET is far less than Schottky diode of asynchronous design.

Over Current Protection The Over Current Protection was very popular implemented on the Baby AT or ATX 3.3V/5V/12V switching power supply. However, the new generation Celeron PPGA CPU uses different voltage that have regulator to transfer 5V to CPU voltage (for example, 2.0V), and make 5V over current protection useless. AX3L with switching regulator onboard support CPU over current protection, in conjunction with 3.3V/5V/12V power supply provide the full line over current protection.

Overview

CPU and Housing Fan Monitoring AX3L has one more "fan monitoring" function to prevent system overheat. There are two fan connectors, one is for CPU and the other can be an extra housing fan. The system will report and alarm fan malfunction though utility software such as Hardware Monitor utility (Small Icon for Hardware Monitoring).

CPU Thermal Protection AX3L has a special thermal detection circuit to have warning through application software when the temperature is higher than a predefined value.

System Voltage Monitoring Further more, AX3L implements a voltage monitoring system, As you turn on your system, this smart design will continue to monitor your system working voltage. If any of the system voltage is over the component's standard. There will be alarm though utility software such as Hardware Monitor utility (Small Icon for Hardware Monitoring) for a warning to user.

Full-range CPU core voltage This motherboard supports the CPU core voltage from 1.3V to 2.05V, that can be applied to various CPU type in future.

Resetable Fuse This motherboard implements resetable fuses to prevent any accidental short circuit caused by keyboard or USB devices hot plug.

FCC DoC certificate AX3L has passed FCC DoC test. The radiation is very low, you can use any kind of housing.

Powerful Utility Software AOpen Bonus Pack CD disc contains many useful utilities, such as Norton Antivirus, AOchip, Hardware Monitoring Utility, and Suspend to Hard Drive utility.

Note: This motherboard isbattery-less,that means the RTC (real time clock) can keep running without battery as long as the power cord is plugged. But in case of power failure or the power cord unplugged, you need to reset date and time from "Standard CMOS Setup" section of BIOS Setup. For more information, please see "Chapter 3 BIOS Setup".

1.2 APM Suspend to Hard Drive

Suspend to Hard Drive 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 Win95 booting process and run your application again. If your memory is 16MB, normally, you need to reserve at least 16MB HDD space to save your memory image. Note that you have to use VESA compatible PCI VGA (AOpen PV70/PT70), Sound Blaster compatible sound card and sound driver that supports APM (AOpen AW32/AW35) for Suspend to Hard Drive to work properly. Of course, we recommend choosing AOpen products for best compatibility.

To use Suspend to Hard Drive:

1-4

Overview

1.Go into BIOS setup, Power Management Æ Suspend Mode Option, select "Suspend to Disk".

2.Go into BIOS setup, PNP/PCI Configuration Æ PnP OS Installed, select "No". This can give BIOS the capability to allocate system resources for Suspend to Hard Drive.

3.Boot up your system into DOS command prompt. If you are Win'95 user, Please restart your Windows 95 under "Command Prompt" by pressing "F8" while system shows "Windows 95 Starting ...". Choose "Safe Mode Command Prompt Only" from selection so that system will start in DOS command prompt.

4.Copy AOZVHDD.EXE to the root directory of your C: drive.

5.Option 1: Use /file switch (applied to FAT16 file system):

Please use following command to create a hidden file in the root directory of your hard disk for Suspend to Hard Drive to save the system status and memory image.

C:>AOZVHDD /c /file

Please make sure that you have enough continuous HDD space for creating this hidden file. For example, if you have 32MB of system memory and 4MB of VGA memory, you need at least 36MB (32MB + 4MB) of continuous HDD space. If AOZVHDD failed to allocate the HDD space, you may run "DEFRAG" Utility or "Disk Defragmenter" which come with MSDOS or Win'95 to free HDD space.

1-5

Overview

Option2: Use /partition switch (applied to FAT16/FAT32 file system):

To create a separate partition for Suspend to Hard Drive, please make sure you have reserved a free partition. We suggest you reserve the free partition which space is appropriate for your future memory expansion. For example, if you have 32MB of system memory and 4MB of VGA memory currently, but you plan to upgrade system memory to 64MB in the near future, then you may reserve a 68MB (64MB+4MB) space by using a disk utility (such as fdisk). Next, use following command to create a suspend partition:

C:>AOZVHDD /c /partition

If there is no extra free partition and you don't want your data lost, please do not use this partition method.

6.After creating above partition or hidden file, please reboot your system.

7.Push suspend switch (momentary mode) or use Win95 Suspend icon to force system goes into Suspend to Hard Drive mode and then turn system power off by power switch of your power supply.

8.Next time when you turn on your system, it will resume to your original work automatically.

Warning: Note that Intel Bus Master and Ultra DMA/33 IDE driver are not fully compatible with Suspend to Hard Drive function, installing these drivers may cause the system unstable. Under this situation, please uninstall the drivers.

Warning: This function does not support SCSI hard disks.

1.3 Zero Voltage Wake on Modem

The Wake on Modem discussed here is to wakeup from true power off (identified by fan of power supply is off), This motherboard still supports traditional green PC suspend mode but it is not discussed here.

With the help ATX soft power On/Off, it is possible to have system totally power off (The traditional suspend mode of power management function does not really turn off the system power supply), and wakeup to automatically answer a phone call such as answering machine or to send/receive fax. You may identify the true power off by checking fan of your power supply. Both external box modem and internal modem card can be used to support Wake on Modem, but if you use external modem, you have to keep the box modem always power-on.AOpen AX3L and internal modem card implement special circuit (patent applied) and make sure the modem card works properly without any power. We recommend choosing AOpen modem card (MP56) for Wake on Modem applications.
