Overview
AX6BC EZ is a new generation Pentium II / Pentium III based system board
that utilizes Intel 82440ZX/BX AGPset on ATX PCI/ISA platform. This AGPset
is designed for the Pentium II / Pentium III CPU, and supports new
architectures such as a high speed AGP graphics port, SDRAM, Ultra DMA/33,
Bus master IDE and USB ports. It has three Dual in-line Memory Module
(DIMM) slots that allow to install SDRAM memory and expand up to a
maximum of 512MB. Since the cache is on the Pentium II CPU card
(connector SLOT1), there is no secondary level cache onboard. Also, AX6BC
EZ uses a 2M bit Flash ROM BIOS to reserve for future new functions.

In addition to the above features, AX6BC EZ also implements many special
features as follows.
features as follows.
Jumper-less Design Pentium II / Pentium III VID signal and SMbus clock
generator provide CPU voltage auto-detection and allows the user to set the
CPU frequency through the CMOS 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. The only jumper left is to
clear the CMOS, which is a safety hook if you forget the password.

Full-range CPU Core Voltage This motherboard supports a CPU core voltage
from 1.3V to 3.5V, that can be applied to various CPU types in future.

Adjustable CPU Voltage This motherboard supports Pentium II / Pentium III /
Celeron VID function, the CPU core voltage is automatically detected, and
ranges from 1.3V to 3.5V. But for the convenience of overclockers, the CPU
voltage is also adjustable in the BIOS Setup.

Battery-less Motherboard This motherboard implements EEPROM and a
special circuit (patent applied) that allows you to save your current CPU and
CMOS Setup configurations without the need of a battery. The RTC (real time
clock) can also keep running as long as the 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.
