Introduction
1-2 Chipset Overview
The VIA Apollo Pro 266T chipset is a high performance, cost-effective and
energy-efficient chipset for the implementation of AGP/V-Link/PCI/LPC com-
puter systems based on 64-bit, 370 Pentium III (66/100/133 MHz) proces-
sors.
VIA's Apollo Pro 266T chipset consists of two major components: the
VT8633 V-Link Memory Host System controller (North Bridge) and the
VT8233 V-Link Client PCI/LPC controller (South Bridge). The VT8633 Host
System Controller provides superior performance between the CPU, DIMMs,
AGP bus and V-Link inferface with pipelined, burst and concurrent opera-
tion. The VT8233 V-Link Client controller is a highly integrated PCI/LPC
controller. Its internal bus structure is based on a 66 MHz PCI bus that
provides a 2x bandwidth. The VT8233 integrated Clint V-Link controller,
which supports a 266 MB bandwidth between the Host/Client V-Link inter-
face, provides a V-Link PCI and V-Link LPC controller. It supports five PCI
slots arbitration and decoding for all integrated functions and an LPC bus.
Memory Support and AGP Capability
The VT8633 supports up to 4 GB of SDRAM memory. The DRAM controller
supports both SDRAM and VCSDRAM (Virtual Channel SDRAM) in a flexible
mix/match manner. The SDRAM interface allows for zero wait state burst-
ing between the DRAM and the data buffers at 66/100/133 MHz.
The VT8633 Controller also supports full AGP v.2.0 capability for maximum
bus utilization including 2x and 4x mode transfer, SBA (Side Band Address-
ing), Flush/Fence commands and pipelined grants. The VT8633 also pro-
vides flexible CPU/AGP/PCI remapping control, which supports major AGP-
based 3D and DVD multimedia accelerators.
Recovery from AC Power Loss
The BIOS provides a setting that alllows 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 power switch to turn the system back on) or for it to return
automatically 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."

SUPER P3TDDE User's Manual

1-3 Special Features
Advanced Communications Riser (ACR)
The ACR (Advanced Communications Riser) combines several existing com-
munications buses with new and advanced communications buses to pro-
vide for low-cost, high-performance communications solutions. The ACR
Specification supports modem, audio, Local Area Network (LAN), and Digital
Subscriber Line (DSL). Pins are also reserved for future wireless bus
support. The ACR Specification enables riser-based broadband communi-
cations, networking peripheral and audio subsystem designs. ACR accom-
plishes this in an open-standards context.
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the SUPER
P3TDDE motherboard.
Seven Onboard Voltage Monitors for the CPU Core, Chipset
Voltage, +3.3V, ±±
±±
±5V and ±±
±±
±12V
The onboard voltage monitor will scan these seven voltages continuously.
If a voltage becomes unstable, the monitor 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.
Four-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 manage-
ment 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 activate the thermal control fan whenever the CPU temperature ex-
ceeds 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

Chapter 1: Introduction
1-11
Introduction
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.
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
(optional). 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 insuf-
ficient 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 of current and auto-sense voltage IDs ranging from 1.3V to 3.5V. This
will allow the regulator to run cooler and thus make the system more stable.

SUPER P3TDDE User's Manual

1-5 ACPI/PC 99 Features
ACPI is an acronym for Advanced Configuration and Power Interface. The
ACPI specification defines a flexible and abstract hardware interface that
provides a standard way to integrate power management features through-
out a PC system, including its hardware, operating system and application
software. This enables the system to turn on and off peripherals such as
CD-ROMs, network cards, hard disk drives and printers automatically. 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
provides a generic system event mechanism for Plug and Play and an oper-
ating system-independent interface for configuration control. ACPI lever-
ages the Plug and Play BIOS data structures while providing a processor
architecture-independent implementation that is compatible with both Win-
dows 98, Windows NT and Windows 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.
BIOS Support for USB Keyboard
If the USB keyboard is the only keyboard in the system, the keyboard will
function as a normal keyboard during system boot-up.

Chapter 1: Introduction
1-13
Introduction
Real Time Clock Wake-Up Alarm
Although the PC may be perceived to be off when not in use, it is still
capable of responding to preset wake-up events. In the BIOS, the user can
set a timer to wake-up the system at a predetermined time.
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(s) 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 main 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
power up a computer remotely that is powered off. Remote PC setup,
updates and 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 enabled 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.

SUPER P3TDDE User's Manual

1-7 Super I/O
The functions of the disk drive adapter for 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 selection, 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 four 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 communica-
tion 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. 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.
At any given time, the Super I/O supports one of the followinga : PC-com-
patible 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 Con-
figuration and Power Interface), which includes support of legacy and ACPI
power management through an SMI or SCI function pin. It also features
auto power management 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 (Ad-
vanced Power Management).
The SUPER P3TDDE accommodates ATX power supplies. Although most
power supplies generally meet the specifications required by the CPU, some
are inadequate.
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.
