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 P8SGA motherboard. The P8SGA supports single Intel Pentium®4
Processor (the Prescott Processor) in the 775-Land Grid Array Package at a sys-
tem bus speed of 800/533 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 motherboard 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/products/motherboard/) for updates on this motherboard. This product is in-
tended to be professionally installed.
Manual Organization
Chapter 1 includes a checklist of what should be included in your mainboard box,
describes the features, specifications and performance of the P8SGA mainboard
and provides detailed information about the chipset.

1-2 Chipset Overview
The Intel Grantsdale (915G) chipset contains two primary components: the Graphics
Memory Controller Hub (GMCH) and the I/O Controller Hub (ICH6). The Grantsdale
(915G) provides the performance and feature-set required for high-end single-pro-
cessor desktop solutions.
Graphics Memory Controller Hub (GMCH)
The function of the GMCH is to manage the data flow between five interfaces: the
CPU interface Front Side Bus (FSB), System Memory Interface (DRAM controller),
PCI Express Graphic Interface, I/O Controller and the Direct Media Interface (DMI).
The GMCH is optimized for the Prescott Processors in an LGA775 Package. It
supports one or two channels of unbuffered, non-ECC DDR 400/333 SDRAM. It
also supports the PCI-Express-based external graphics solutions.
The ACPI component provides the data buffering and interface arbitration required
for the system to interface efficiently. The Direct Media Interface (DMI) is a point-
to-point interconnection between the Grantsdale GMCH and the ICH6. Virtually
all communication between the GMCH 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 ICH6 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
Graphics Features/Display
The Grantsdale GMCH provides an integrated graphics accelerator, delivering 3D,
2D and video capabilities. It also provides interfaces to a progressive scan analog
monitor and two DVO devices. It is compliant with DVI specification and has a
high-speed interface to a digital display.

P8SGA User’s Manual
1-3 PC Health Monitoring
This section describes the PC health monitoring features of the P8SGA. The moth-
erboard has an onboard System Hardware Monitor chip that supports PC health
monitoring.
Eight Onboard Voltage Monitors for the CPU Core, Chipset
Voltage, +3.3V, +3.3V standby, +5V, 1.5V, Vbat and ±12V
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 sensitivity of the voltage
monitor.
Fan Status Monitor with Firmware/Software
The PC health monitor can check the RPM status of the cooling fans via Supero
Doctor.
CPU Overheat LED and Control
This feature is available when the user enables the CPU overheat monitoring in the
BIOS. This allows the user to define an overheat temperature threshold. When this
temperature reaches the threshold, 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 to reduce heat dissipation.
1-4 Power Configuration Settings
This section describes features of your motherboard that deal with power and
power settings.
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
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 presses the power button, the system will enter

Chapter 1: Introduction
1-11
a SoftOff state. The monitor will be suspended and the hard drive will spin down.
Pressing 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 press and hold the power button for 4 seconds. The power will turn off
and no power will be provided to the motherboard.
Wake-On-Ring (WOR) Header
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.
1-5 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 P8SGA 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 recom-
mended.
It is strongly recommended that you use a high quality power supply that meets
12V ATX power supply Specification 1.1 or above. It is also required that the 12V
4-pin power connection (J41) be used for high-load configurations. In areas 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.
1-6 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 selection, a clock genera-
tor, 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.

1-12
P8SGA User’s Manual
It also provides two high-speed, 16550 compatible serial communication ports
(UARTs). 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 Configuration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through a SMI or SCI function pin. It also features auto power management
to reduce power consumption.

2-1 Static-Sensitive Devices
Electric Static Discharge (ESD) can damage electronic components. To prevent
damage to your system board, it is important to handle it very carefully. The following
measures are generally sufficient to protect your equipment from ESD.
Precautions
• Use a grounded wrist strap designed to prevent static discharge.
• Touch a grounded metal object before removing the board from the antistatic
bag.
• Handle the board by its edges only; do not touch its components, peripheral
chips, memory modules or gold contacts.
• When handling chips or modules, avoid touching their pins.
• Put the motherboard and peripherals back into their antistatic bags when not in
use.
• For grounding purposes, make sure your computer chassis provides excellent
conductivity between the power supply, the case, the mounting fasteners and
the motherboard.
• Use only the correct type of CMOS onboard battery as specified by the Manufac-
turer. Do not install the CMOS onboard battery upside down to avoid a possible
explosion.
Unpacking
The motherboard is shipped in antistatic packaging to avoid static damage. When
unpacking the board, make sure the person handling it is static protected.
Installation Procedures
Follow the procedures as listed below to install the motherboard into a chassis:
1. Install the processor and the heatsink to the motherboard.
2. Install the motherboard in the chassis.
3. Install the memory modules and add-on cards.
4. Connect cables and install controllers/drivers.
