AOpen AX6F-OV User Manual

Chapter 1

Overview

The AX6F is a high-performance Pentium II (Klamath) based system board
that utilizes the PCI/ISA architecture and ATX form factor. It integrates the
Intel 82440FX PCIset, a Ultra I/O controller, and a PCI mode 4 enhanced
IDE controller with bus master to enhance system performance. It has four
single in-line memory module (SIMM) that allows memory up to a
maximum of 512MB. There is no second level cache onboard, since the
cache is on the Pentium II CPU card (connector SLOT1).

Another feature that AX6F has implemented is CPU Thermal Protection. A
special circuit is under the CPU heatsink, when temperature is higher than 55
degree C, the CPU speed will automatically slow down and there will be
warning from BIOS and also ADM (AOpen Desktop Manager, similar as Intel
LDCM), if ADM is installed.
