Introduction
1-2 Chipset Overview
The ServerWorks Grand Champion LE
TM
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
a 144-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
