Overview

AX6BC is a new generation Pentium II based system board that utilizes Intel

82440BX AGPset on ATX PCI/ISA platform. This AGPset is designed for

Pentium II CPU, and supports new architectures such as high speed AGP

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

three Dual in-line Memory Module (DIMM) that allow to install SDRAM

memory and expand up to a maximum of 768MB. Since the cache is on the

Pentium II CPU card (connector SLOT1), there is no second level cache

onboard Also, AX6BC uses 2M bit Flash ROM BIOS to reserve for future new

functions.

Not only above features, AX6BC also implements many special features as

following.

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 AX6BC 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
