Overview

AX6B Plus is a new generation Pentium II based system board that features an

onboard Adaptec AIC-7880 SCSI chip. It 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 four Dual in-line Memory

Module (DIMM) that allow to install SDRAM memory and expand up to a

maximum of 1GB. Since the cache is on the Pentium II CPU card (connector

SLOT1), there is no second level cache onboard. Also, AX6B Plus uses 2M bit

Flash ROM BIOS to reserve for future new functions.

Not only above features, AX6B Plus 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 AX6B Plus 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
