Preface
About This Manual
This manual is written for system integrators, PC technicians and
knowledgeable PC users. It provides information for the installation and use
of the P8SAA+ motherboard. The P8SAA+ supports single Intel
Pentium
®
4 Processor (the Prescott Processor) in the 775-Land Grid Array
Package at a system bus speed of 1066 MHz/800 MHz/533 MHz. The
Pentium 4 Processor in the 775-Land Grid Array Package is housed in a
Flip-Chip Land Grid Array (FC-LGA4) package that interfaces with the moth-
erboard via an LGA775 socket. The package consists of a processor core
mounted on a substrate land-carrier. An integrated heat spreader (IHS) is
attached to the package substrate and core and serves as the contacting
surface for processor component thermal solutions, such as a heatsink.
Please refer to the motherboard specifications pages on our web site (http:/
/www.supermicro.com/Product) for updates on supported processors.
This product is intended to be professionally installed.

1-2 Chipset Overview
Intel’s Alderwood (925XE) chipset, designed for use with the Pentium 4
LGA 775 CPU, is comprised of two primary components: the Memory Con-
troller Hub (MCH) and the I/O Controller Hub (ICH6R). The Alderwood
(925XE) provides the performance and feature-set required for the high-
end desktop and the UP workstation market.
Memory Controller Hub (MCH)
The function of the MCH is to manage the data flow between five inter-
faces: the CPU interface Front Side Bus (FSB), System Memory Interface
(DRAM controller), PCI Express Graphic Interface, I/OController and the Di-
rect Media Interface (DMI). The MCH is optimized for the Pentium 4 proces-
sors in an LGA775 Package. It supports one or two channels of unbuf-
fered, Non-ECC DDR2 533/400 SDRAM. It also supports the PCI-Express-
based external graphics solutions.
The ACPI component provides the data buffering and interface arbitration
required to ensure that system interfaces operate efficiently. The Direct
Media Interface (DMI) is a point-to-point interconnect between the
Alderwood MCH and the ICH6R. Virtually all communication between the
MCH and the ICH occurs over the Direct Media Interface. DMI supports 2GB/
s (IGB/s each direction) of bandwidth, using a 100 MHz differential clock.
Intel ICH6R System Features
The I/O Controller Hub provides the I/O subsystem with access to the rest
of the system. Functions and capabilities include:
*PCI Express Base Specification, Rev. 1.0a-compliant
*PCI 2.3
*ACPI Power Management Logic Support
*USB host interface
*Enhanced DMA Controller
*System Management Bus
*Low Pin Count (LPC) Interface
*Firmware Hub (FWH) Interface

1-3 PC Health Monitoring
This section describes the PC health monitoring features of the the P8SAA+.
The motherboard has an onboard System Hardware Monitor chip that sup-
ports PC health monitoring.

The onboard voltage monitor will scan these 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 sensi-
tivity of the voltage monitor.
Fan Status Monitor with Firmware/Software Speed Control
The PC health monitor can check the RPM status of the cooling fans. The
onboard fans are controlled by Thermal Management via BIOS.
CPU Overheat/Fan Fail 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 reaches the threshold or a fan failure occurs,
the CPU thermal trip feature will be activated and it will send a signal to the
Speaker LED and, at the same time, the CPU speed will be decreased.
1-4 Power Configuration Settings
This section describes features of your motherboard that deal with power
and power settings.
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.
Chapter 1: Introduction
1-11
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, it will function like
a normal keyboard during system boot-up.
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.
1-5 ACPI Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI
specification defines a flexible and abstract hardware interface that pro-
vides a standard way to integrate power management features throughout
a PC system, including its hardware, operating system and application soft-
ware. 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, tele-
phones 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 2000 and Windows NT 5.0.

quired circuitry in the system alive. In case the system malfunctions andyou
want to turn off the power, just depress and hold the power button for 4
seconds. This option can be set in the Power section of the BIOS Setup
routine.
Wake Ring-On (WOR)
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.
Chapter 1: Introduction
1-13
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 of 1 GHz and faster.
The P8SAA+ accommodates 12V ATX power supplies. Although
most power supplies generally meet the specifications required by the CPU,
some are inadequate. A 2 amps of current supply on a 5V Standby rail is
strongly recommended.
The P8SAA+ accommodates ATX power supplies. It is strongly recom-
mended that you use a high quality power supply that meets ATX power
supply Specification 2.02 or above. You should use one that will supply at
least 350W of powerAlso your power supply must supply 1.5A for the
Ethernet ports. It must also be SSI compliant (info at http://
www.ssiforum.org/). Additionally, in areas where noisy power transmis-
sion 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. (*Note: an additional
12V 4-pin power (J41) connection is required for high-load system
configurations.)
Wake-On-LAN (WOL)
Wake-On-LAN is defined as the ability of a management application to re-
motely power up a computer that is powered off. Remote PC setup, up-
dates 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
motherboard has 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.

1-7 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 two 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 sys-
tem. 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 provides functions that comply with ACPI (Advanced Con-
