Introduction
1-2 Chipset Overview
The ServerWorks ServerSetTM III LE is a high-performance core logic chipset
that consists of a North Bridge and a South Bridge.
The North Bridge includes an integrated main memory subsystem and a dual
channel PCI bus that bridges the processor bus to a 64-bit PCI bus and a
32-bit PCI bus. The North Bridge also packs and unpacks data for PCI
accesses, which reserves 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.
The North and South Bridges communicate over a serial bus that uses the
PCI clock as a timing reference. This serial bus uses a single pin on both
bridges to send a 4-bit word for transmitting commands back and forth.
1-3 Special Features
ATI Graphics Controller
The P3TDLR has an integrated ATI video controller based on the Rage XL
graphics chip. The Rage XL fully supports sideband addressing and AGP
texturing. An 8 MB graphics memory chip has been integrated aboard the
P3TDLR to provide graphics memory. 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 use an image file to recover your
BIOS 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 press the

SUPER P3TDLR User's Manual

Introduction
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 BIOS chapter of this
manual to change this setting. The default setting is "Always OFF."
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the SUPER
P3TDLR. All have an onboard System Hardware Monitor chip that supports
PC health monitoring.
Seven Onboard Voltage Monitors for the CPU Core, Chipset
Voltage, +5V and +12V
The onboard voltage monitor will scan these seven voltages continuously. Once
a voltage becomes unstable, it will give a warning or send an error message to
the screen. Users can adjust the voltage thresholds to define the sensitivity of
the voltage monitor.
Fan Status Monitor with Firmware/Software On/Off Control
The PC health monitor can check the RPM status of the cooling fans. The
onboard 3-pin CPU and chassis fans are controlled by the power management
functions. The thermal fan is controlled by the overheat detection logic.
Environmental Temperature Control
The thermal control sensor monitors the CPU temperature in real time and will
turn on the thermal control fan whenever the CPU temperature exceeds a user-
defined threshold. The overheat circuitry runs independently from the CPU. It
can continue to monitor for overheat conditions even when the CPU is in sleep
mode. Once it detects that the CPU temperature is too high, it will automatically
turn on the thermal control fan to prevent any overheat damage to the CPU. The
onboard chassis thermal circuitry can monitor the overall system temperature
and alert users when the chassis temperature is too high.
CPU Fan Auto-Off in Sleep Mode
The CPU fan activates when the power is turned on. It can be turned off when
the CPU is in sleep mode. When in sleep mode, the CPU will not run at full
power, thereby generating less heat.

Chapter 1: Introduction
1-11
Introduction
CPU Overheat LED and Control
This feature is available when the user enables the CPU overheat warning
function in the BIOS. This allows the user to define an overheat tempera-
ture. When this temperature is exceeded, both the overheat fan and the
warning LED are triggered.
System Resource Alert
This feature is available when used with Intel's LANDesk Client Manager (op-
tional). It is used to notify the user of certain system events. For example, if
the system is running low on virtual memory and there is insufficient hard drive
space for saving the data, you can be alerted of the potential problem.
Hardware BIOS Virus Protection
The system BIOS is protected by hardware so that no virus can infect the BIOS
area. The user can only change the BIOS content through the flash utility
provided by SUPERMICRO. This feature can prevent viruses from infecting the
BIOS area and destroying valuable data.
Auto-Switching Voltage Regulator for the CPU Core
The auto-switching voltage regulator for the CPU core can support up to 20A
current and auto-sense voltage IDs ranging from 1.4V to 3.5V. This will allow the
regulator to run cooler and thus make the system more stable.
1-5 ACPI/PC 98 Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI speci-
fication defines a flexible and abstract hardware interface that provides a stan-
dard way to integrate power management features throughout a PC system,
including its hardware, operating system and application software. This enables
the system to automatically turn on and off peripherals such as CD-ROMs,
network cards, hard disk drives and printers. This also includes consumer
devices connected to the PC such as VCRs, TVs, telephones and stereos.
In addition to enabling operating system-directed power management, ACPI pro-
vides a generic system event mechanism for Plug and Play and an operating
system-independent interface for configuration control. ACPI leverages the Plug
and Play BIOS data structures while providing a processor architecture-indepen-
dent implementation that is compatible with both Windows 98 and Windows NT

SUPER P3TDLR User's Manual
1-12
Introduction
5.0. Note: To utilize ACPI, you must reinstall Windows 98/2000. You can
check to see if ACPI has been properly installed by looking for it in the
Device Manager, which is located in the Control Panel in Windows.
Microsoft OnNow
The OnNow design initiative is a comprehensive, system-wide approach to
system and device power control. OnNow is a term for a PC that is always
on but appears to be off and responds immediately to user or other re-
quests.
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start
blinking to indicate that the CPU is in suspend mode. When the user presses
any key, the CPU will wake-up and the LED will automatically stop blinking and
remain on.
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a system
suspend button. When the user depresses the power button, the system will
enter a SoftOff state. The monitor will be suspended and the hard drive will spin
down. Depressing the power button again will cause the whole system to wake-
up. During the SoftOff state, the ATX power supply provides power to keep the
required circuitry in the system alive. In case the system malfunctions and you
want to turn off the power, just depress and hold the power button for 4 seconds.
The power will turn off and no power will be provided to the motherboard.
External Modem Ring-On
Wake-up events can be triggered by a device such as the external modem ringing
when the system is in the SoftOff state. Note that external modem ring-on can
only be used with an ATX 2.01 (or above) compliant power supply.
Wake-On-LAN (WOL)
Wake-On-LAN is defined as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, updates and

Chapter 1: Introduction
1-13
Introduction
asset tracking can occur after hours and on weekends so that daily LAN
traffic is kept to a minimum and users are not interrupted. The motherboards
have a 3-pin header (WOL) to connect to the 3-pin header on a Network
Interface Card (NIC) that has WOL capability. Wake-On-LAN must be en-
abled in BIOS. Note that Wake-On-Lan can only be used with an ATX 2.01
(or above) compliant power supply.
1-6 Power Supply
As with all computer products, a stable power source is necessary for
proper and reliable operation. It is even more important for processors that
have high CPU clock rates.
The SUPER P3TDLR accommodates ATX power supplies. Although most
power supplies generally meet the specifications required by the CPU, some
are inadequate. You should use one that will supply at least 300W of
power - or even higher wattage power supply is recommended for high-
load configurations. Also your power supply must provide a +5V standby
voltage that supplies at least 1.5A of current.
It is strongly recommended that you use a high quality power supply that
meets ATX power supply Specification 2.02 or above. Additionally, in ar-
eas where noisy power transmission is present, you may choose to install
a line filter to shield the computer from noise. It is recommended that you
also install a power surge protector to help avoid problems caused by
power surges.
1-7 Super I/O
The disk drive adapter functions of the Super I/O chip include a floppy disk
drive controller that is compatible with industry standard 82077/765, a data
separator, write pre-compensation circuitry, decode logic, data rate selec-
tion, a clock generator, drive interface control logic and interrupt and DMA
logic. The wide range of functions integrated onto the Super I/O greatly
reduces the number of components required for interfacing with floppy disk
drives. The Super I/O supports 360 K, 720 K, 1.2 M, 1.44 M or 2.88 M disk
drives and data transfer rates of 250 Kb/s, 500 Kb/s or 1 Mb/s. It also
provides two high-speed, 16550 compatible serial communication ports
(UARTs), one of which supports serial infrared communication. Each UART
includes a 16-byte send/receive FIFO, a programmable baud rate generator,
complete modem control capability and a processor interrupt system.
Each UART includes a 16-byte send/receive FIFO, a programmable baud

Introduction
rate generator, complete modem control capability and a processor inter-
rupt system. Both UARTs provide legacy speed with baud rate of up to
115.2 Kbps as well as an advanced speed with baud rates of 250 K, 500 K,
or 1 Mb/s, which support higher speed modems.
The Super I/O supports one PC-compatible printer port (SPP), Bi-directional
Printer Port (BPP) , Enhanced Parallel Port (EPP) or Extended Capabilities Port
(ECP).
The Super I/O provides functions that comply with ACPI (Advanced Configuration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through an SMI or SCI function pin. It also features auto power manage-
ment to reduce power consumption.
The IRQs, DMAs and I/O space resources of the Super I/O can flexibly adjust to
meet ISA PnP requirements, which suppport ACPI and APM (Advanced Power
Management).
