Chapter 1

Overview

The AX6L is a new generation Pentium II based system board that utilizes Intel

82440LX chipset on ATX PCI/ISA platform. This chipset is designed for

Pentium II CPU, and supports new architectures such as high speedAGP

graphic port, SDRAM, Ultra DMA/33, Bus master IDE and USB port. It has

four Dual in-line Memory Module (DIMM) that allow to mix 3V EDO and

SDRAM memory and expand up to a maximum of1GB. There is no second

level cache onboard, since the cache is on the Pentium II CPU card

(connector SLOT1). Also, AX6L uses 2M bit Flash ROM BIOS to reserve for

future new functions.

Not only above features, AX6L implements most advanced technology such as

user-friendly Jumper-less configuration, CMOS and RTC battery-less backup,

Synchronous switching regulator, CPU thermal protection, CPU fan

monitoring, System voltage monitoring, Over current protection, Modem Wake

Up and Suspend to Hard Drive.

Jumper-less Design

Pentium II VID signal and SMbus clock generator provide CPU voltage auto-

detection and 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 base

jumper-less design are eliminated. There will be no worry of wrong CPU

voltage detection and no need to re-open the 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 Motherboard

AX6L 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.

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 VESA compatible PCI VGA,

Sound Blaster compatible sound card with APM driver, for Suspend to Hard

Drive to work properly.

Internal Modem Card Wake-up

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

Modem Wake Up. The AX6L and MP56 internal modem card implement

special circuit (patent applied) to make sure the modem card work properly

without any power.

RTC Wake Up Timer

The Wake Up Timer is more like an alarm, which wakes up and power on your

system at a pre-defined time for specific application. It can be set to wake up

everyday or on specific date within a month. The date/time accurate is second.

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. AX6L

implements high efficient synchronous switching design that the temperature

of MOS FET is far less than Schottky diode of Asynchronous design.

Over Current Protection Circuit

The Over Current Protection was very popular implemented on the Baby AT or

ATX 3.3V/5V/12V switching power supply. But unfortunately, the new

generation Pentium II CPU uses different voltage that have regulator to

transfer 5V to CPU voltage (for example, 2.8V), and make 5V over current

protection useless. AX6L 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.

CPU Thermal Protection

AX6L has a special thermal detection circuit to have warning through

application software when the temperature is higher than a predefined value.

CPU and Housing Fan Monitoring

AX6L has one more "fan monitoring" function to prevent system overheat.

There are two fan connectors, one is for CPU and the other can be a extra

housing fan. The system will report and alarm fan malfunction though utility

software such as HWMON2 (Small Icon for Hardware Monitoring).

System Voltage Monitoring

Further more, AX6L 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 HWMON2 (Small Icon for

Hardware Monitoring) for a warning to user.

FCC DoC certificate

AX6L has passed FCC DoC test. The radiation is very low, you can use any

kind of housing.

1.2 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 second 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 PV60/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 to use AOpen products for best compatibility.

To use Suspend to Hard Drive:

1. Go into BIOS setup, Power Management Suspend Mode Option, select

"Suspend to Drive".

2. Go into BIOS setup, PNP/PCI Configuration PnP OS Installed, select

"No". This can give BIOS the capability to allocate system resources for

Suspend to Hard Drive.

3. Bootup your system into DOS command prompt. If you are Win'95 user,

Please restart you Windows 95 under "Command Prompt" by pressing "F8"

while system shows "Windows 95 Starting ...". Choose "Command

Prompt Mode" from selection so that system will start in DOS command

prompt.

4. Use utility "AOZVHDD" to create a partition in your hard disk drive. This

partition is used to save your system status and memory image. Just type:

C:>AOZVHDD /c /partition /M:mmm

Where mmm is the partition space you want to create. It is recommended

to reserve enough space for your feature memory expansion. For example,

if you plan to have 64MB main memory and 4MB VGA memory in the near

future. Please create at least 64+4=68MB.

If you are using FAT32 file system, please use this partition method.

5. There is another method to create a hidden file in your hard disk drive for

Suspend to Hard Drive to save your 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 16MB of system memory,

you need at least 16MB (+ VGA memory size) of continuous HDD space. If

Overview

1-7

AOZVHDD failed to allocate the HDD space, you may run "DEFRAG" Utility

or "Disk Defragmenter" which come with MS-DOS or Win'95 to free HDD

space.

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 you turn on your system, it will resume to your original work

automatically.

1.3 Modem Wake Up

The Modem Wake Up 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 Modem

Wake Up, but if you use external modem, you have to keep the box modem

always power-on. AOpen AX6L and internal modem card implement special

circuit (patent applied) and make sure the modem card works properly without

any power. We recommend you choose AOpen modem card (MP56) for

Modem Wake Up applications.
