SUPER MICRO Computer SUPER X5DLR-8G2+ Chipset Overview, Special Features, ATI Graphics Controller

Chapter 1: Introduction

1-2 Chipset Overview

The ServerWorks Grand Champion LETM is a high-performance work station SystemSet core logic chipset that consists of a North Bridge, a South Bridge and an IO bridge.

The North Bridge interfaces directly to the processor bus and integrates the functions of the main memory subsystem and the IMB bus interface unit. The memory subsystem consists of an 8-DIMM configuration accessed over

a144-bit memory bus (most chipsets have a 72-bit memory bus), which provides a significant boost in performance.

The South Bridge provides various integrated functions, including the PCI to ISA bridge and support for UDMA100, security (passwords and system protection), Plug & Play, USBs, power management, interrupt controllers and the SMBus.

The CIOBX2 is an integrated IO bridge that provides high-performance data flow between the IMB interface and the dual peer PCI-X bus interfaces. The X5DL8-GG has two CIOBX2 bridges (four buses).

1-3 Special Features

ATI Graphics Controller

The X5DL8-GG/X5DLR-8G2+/X5DLR-8G2 has an integrated ATI video con- troller based on the Rage XL graphics chip. The Rage XL fully supports sideband addressing and AGP texturing. This onboard graphics package can provide a bandwidth of up to 512 MB/sec over a 32-bit graphics memory bus.

BIOS Recovery

The BIOS Recovery function allows you to recover your BIOS image file if the BIOS flashing procedure fails (see Section 3-3).

Recovery from AC Power Loss

BIOS provides a setting for you to determine how the system will respond when AC power is lost and then restored to the system. You can choose for the system to remain powered off (in which case you must hit the power switch to turn it back on) or for it to automatically return to a power
