Chapter 1: Introduction 1-2 Chipset Overview The ServerWorks ServerSet TM III HE SL is a high-performance core logic chipset that consists of a North Bridge and a South Bridge. Introduction The North Bridge integrates the main memory subsystem and a dual channel PCI bus and bridges the processor bus to a 64-bit PCI bus. The memory subsystem consists of a two-way interleaved 4-DIMM configuration ac- cessed over a 144-bit memory bus (most chipsets have a 72-bit memory bus), which provides a significant boost in performance. The North Bridge also packs and unpacks data for PCI accesses to reserve more processor bandwidth for multiprocessor motherboards.
The South Bridge provides various integrated functions, including the PCI to ISA bridge and support for UDMA33, security (passwords and system pro- tection), Plug & Play, USBs, power management, interrupt controllers and the SMBus. 1-3 Special Features ATI Graphics Controller (P3TDER only) The P3TDER has an integrated ATI video controller 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 on state. See the Power Lost Control setting in the Advanced BIOS Setup section (Peripheral Device Configuration) to change this setting. The de- fault setting is Always On. 1-13
