Introducing the Motherboard
Introduction
Thank you for choosing PM800-M2 motherboard of great performance and with enhanced
function. The PM800-M2 is designed to fit the advanced Intel Pentium 4 processors in the
478-pin package. Based on the Micro-ATX form factor, this motherboard incorporates the
following chipsets: PM800 Northbridge and VT8237 Southbridge chipsets. This motherboard
provides the 800/533/400 MHz front side bus with extra capability.
The PM800 Northbridge provides a high performance, cost-effective and energy efficient
UMA chipset north bridge with embedded UniChromePro graphics core used for the imple-
mentation of desktop personal computer systems. The PM800 implements twelve-level
deep In-Order-Queue, and supports Intel Hyper-Threading Technology to maximize sys-
tem performance for multi-threaded software applications. The PM800 supports asyn-
chronous AGP and CPU interface for flexible system configuration. The Northbridge
interfaces to the Southbridge through a high speed 8 x 66 MHz Data Transfer interconnect
bus, Ultra V-Link.
The VT8237 Southbridge is a highly integrated peripheral controller, it includes V-Link to
PCI and V-Link to LPC controllers. It also integrates Serial ATA and Ultra DMA IDE
controllers, USB2.0 host controller, 10/100MB networking MAC, AC’97, and system
power management controllers. The VT8237 also supports both ACPI (Advanced Configu-
ration and Power Interface) and legacy (APM) power management.
Sufficient expansion is provided for one AGP slot, three 32-bit PCI slots and one optional
CNR slot. It also comes with a concurrent PCI Bus Controller that provides expandability
for add-on peripheral cards. This motherboard is designed in a micro-ATX form factor
using a four-layer printed circuit board and measures 244 mm x 244 mm. In addition to its
excellent performance, the motherboard is featuring a host of high-definition digital media
technologies.
