Chapter 1: Introduction
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 fl ow between fi ve 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 effi ciently. 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 Specifi cation, 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 specifi cation 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 defi ne 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 defi ne 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 Confi guration 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
1-10
Chapter 1: Introduction
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
power supplies generally meet the specifi cations 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 Specifi cation 1.1 or above. It is also required that the 12V
4-pin power connection (J41) be used for high-load confi gurations. In areas where
noisy power transmission is present, you may choose to install a line fi lter 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.
P8SGA accommodates 12V ATX power supplies. Although most
1-6 Super I/O
The disk drive adapter functions of the Super I/O chip include a fl oppy 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 fl oppy 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.
1-11
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 Confi guration
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.

Pin 1 is the corner marked with a triangle).
Please note that the North Key and the
South Key are located vertically in the
CPU housing.
4. Position the motherboard in such a way
that Pin 1 of the CPU socket is located at
the left bottom of the CPU housing.
5. Use your thumb and your index fi nger to
hold the CPU at the North Center Edge and
the South Center Edge of the CPU.
6. Align Pin 1 of the CPU with Pin 1 of the
socket. Once aligned, carefully lower the
CPU straight down to the socket. (**Do not
drop the CPU on the socket. Do not move
the CPU horizontally or vertically. Do not
rub the CPU against the surface or against
any pins of the socket to avoid damage to
the CPU or the socket.)

the four corners of the CPU to make sure
that the CPU is properly installed.
8. Use your thumb to gently push the lever
down and lock it in the hook.
9. If the CPU is properly installed into the
socket, the plastic cap will be automatically
released from the load plate when the lever
is pushed into the hook. Remove the plastic
cap from the motherboard.
(*Warning: Please save the plastic cap.
The motherboard must be shipped with
the plastic cap properly installed to protect
the CPU socket pins. Shipment without
the plastic cap properly installed will cause
damage to the socket pins.)

Installation of the Heatsink
1. Locate the CPU Fan on the mother-
board. (Refer to the layout on Page 1-4
for the CPU Fan location.)
2. Position the heatsink in such a way
that the heatsink fan wires are closest to
the CPU fan and are not interfered with
other components.
3. Inspect the CPU Fan wires to make
sure that the wires are routed through
the bottom of the heatsink.
4. Remove the thin layer of the protec-
tive fi lm from the copper core of the
heatsink.
(*Warning: CPU overheat may occur if
the protective fi lm is not removed from
the heatsink.)
5. Apply the proper amount of thermal
grease on the CPU. (*Note: if your
heatsink came with a thermal pad,
please ignore this step.)
6. If necessary, re-arrange the wires
to make sure that the wires are not
pinched between the heatsink and the
CPU. Also make sure to keep clearance
between the fan wires and the fi ns of
the heatsink.
7. Align the four heatsink fasteners with
the mounting holes on the motherboard.
Gently push the fasteners into the mount-
ing holes until you hear a click.
8. Repeat Step 6 to insert all four heatsink
fasteners into the mounting holes.

2-3 Mounting the Motherboard in the Chassis
All motherboards have standard mounting holes to fi t different types of chassis.
Make sure the locations of all the mounting holes for both the motherboard and the
chassis match. Although a chassis may have both plastic and metal mounting fas-
teners, metal ones are highly recommended because they ground the motherboard
to the chassis. Make sure that the metal standoffs click in or are screwed in tightly.
Then use a screwdriver to secure the motherboard onto the motherboard tray.

2-4 Installing DDR Memory
CAUTION
Exercise extreme care when installing or removing memory modules
to prevent any possible damage.
Memory Module Installation (See Figure 2-2)
1. Insert each DDR memory module vertically into its slot. Pay attention to the
notch along the bottom of the module to prevent incorrect memory installa-
tion.
2. Gently press down on the memory module until it snaps into place.
Support
The P8SGA supports Dual channel, Non-ECC, unbuffered DDR 400/333
(PC3200/2700) SDRAM. Both interleaved and non-interleaved memory
is supported, so you may populate any number of DIMM slots. (Populate
DIMM#1A,DIMM#1B, and/or DIMM#2A, DIMM#2B with memory modules
of the same size and same type will result in the dual channel, two-way
interleaved memory which is faster than the single channel, non-interleaved
memory.)
Figure 2-2. Side and Top Views of DDR Module Installation into Slot
To Install:
Insert module vertically and press down until it snaps into place. Pay attention to the notch.
To Remove:
Use your thumbs gently to push each release tab outward to release the DIMM from the slot.

Fan Headers
There are three fan headers (Fan
1, Fan 2 and Fan3) on the P8SGA.
(See the table on the right for pin defi -
nitions.) These are 4-pin fan headers;
however, the traditional 3-wire fans
are also supported. (Pins #1-#3 of the
fan headers are backward compatible
with the traditional 3-pin fans.) When
a 3-wire fan is used, it will be set to
run at the full speed by default. When
a 4-pin fan is used, the CPU and
chassis fan speeds will be automati-
cally controlled by PWM (Pulse Width
Modulation) via Hardware Monitoring
in the BIOS.
Chassis Intrusion
The Chassis Intrusion header is lo-
cated at JL1. See the board layout
in Chapter 1 for the location of JL1
and the table on the right for pin
defi nitions.

2-7 Jumper Settings
Explanation of Jumpers
To modify the operation of the mother-
board, jumpers can be used to choose
between optional settings. Jumpers cre-
ate shorts between two pins to change
the function of the connector. Pin 1 is
identifi ed with a square solder pad on
the printed circuit board. See the mother-
board layout pages for jumper locations.
Note: On a two-pin jumper, "Closed"
means the jumper is on both pins and
"Open" means the jumper is either on

CMOS Clear
JBT1 is not actually a jumper but consists of two contact pads. To clear the
contents of CMOS, short these pads together by touching them both with a metal
conductor such as the head of a small screwdriver. Note: for ATX power supplies,
you must completely shut down the system and remove the AC power cord before
clearing CMOS.

USB Wake-Up
Use JPUSB jumpers to enable the function of System Wake-Up via USB Devices"
to allow you to wake-up the system by pressing a key on the USB keyboard or by
clicking the USB mouse on your system. The JPUSB jumpers are used together
with the USB Wake-Up function in the BIOS. Enable both the jumpers and the
BIOS setting to allow the system to use this function. See the table on the right
for jumper settings and jumper connections.
(*Note: The default setting for the USB ports is "disabled". However, when the
"USB Wake-Up" function is enabled in the BIOS and the desired USB ports are
enabled via the JPUSB jumper, please be sure to remove all USB devices from
the USB ports whose USB jumpers are set to "disabled"; otherwise, the system
will not go into the standby mode.)

2-8 Parallel, Floppy, Hard Disk, and Audio Connections
Use the following information to connect the fl oppy and hard disk drive cables.
• The fl oppy disk drive cable has seven twisted wires.
• A red mark on a wire typically designates the location of pin 1.
• A single fl oppy disk drive ribbon cable has 34 wires and two connectors to provide
for two fl oppy disk drives. The connector with twisted wires always connects to
drive A, and the connector that does not have twisted wires always connects to
drive B.
• The 80-wire ATA100/66 IDE hard disk drive cable that came with your system
has two connectors to support two drives. This special cable should be used
to take advantage of the speed this new technology offers. The blue connector
connects to the onboard IDE connector interface and the other connector(s) to
your hard drive(s). Consult the documentation that came with your disk drive
for details on actual jumper locations and settings for the hard disk drive.
Parallel Port Connector
The parallel port is located on J30.
Refer to Figure 2-3 for location. See

Introduction to Serial ATA (SATA)
Serial ATA(SATA) is a physical storage interface. It uses a single cable with a
minimum of four wires to create a point-to-point connection between devices. It
is a serial link which supports SATA Transfer rates from 150MBps. Because the
serial cables used in SATA are thinner than the traditional cables used in Paral-
lel ATA(PATA), SATA systems have better airfl ow and can be installed in smaller
chassis than Parallel ATA. In addition, the cables used in PATA can only extend
to 40cm long, while Serial ATA cables can extend up to one meter. Overall, Serial
ATA provides better functionality than Parallel ATA.
Introduction to the Intel ICH6 I/O Controller Hub
Located in the South Bridge of the Intel Grantsdale (915G) chipset, the ICH6 I/O
Controller Hub provides the I/O subsystem with access to the rest of the system. It
supports 2-channel Ultra ATA/100 Bus Master IDE controller (PATA) and two Serial
ATA (SATA) Host Controllers, which support up to two Serial ATA ports and up to
four hard drives. TheICH6 I/O Controller Hub supports the following Parallel ATA
(PATA) and Serial (SATA) device confi gurations:
SATA Operate Modes
You can select from the following modes: Auto, Combined, Enhanced, and SATA
Only Mode. The number of devices supported by these modes are listed below:
*SATA Only: The maximum of 4 devices are supported (4 SATA)
*Auto Mode: The maximum of 6 devices supported (4 SATA + 2 IDE)
*Enhanced Mode: The maximum of 6 devices supported (4 SATA + 2 IDE)
*Combined Mode: The maximum of 4 devices supported (2 SATA + 2 IDE)

Supero Doctor III
The Supero Doctor III program is a Web-based management tool that supports
remote management capability. It includes Remote and Local Management tools.
The local management is called the SD III Client. The Supero Doctor III program
included on the CDROM that came with your motherboard allows you to monitor
the environment and operations of your system. Supero Doctor III displays crucial
system information such as CPU temperature, system voltages and fan status. See
the Figure below for a display of the Supero Doctor III interface.
*Note 1: The default user name and password are ADMIN.
*Note 2: In the Windows OS environment, the Supero Doctor III settings take pre-
cedence over the BIOS settings. When fi rst installed, Supero Doctor III adopts the
temperature threshold settings previously set in the BIOS. Any subsequent changes
to these thresholds must be made within Supero Doctor, since the SD III settings
override the BIOS settings. For the Windows OS to adopt the BIOS temperature
threshold settings, please change the SDIII settings to be the same as those set
in the BIOS.

3-3 Frequently Asked Questions
Question: What type of memory does my motherboard support?
Answer: The P8SGA supports up to 4 GB of non-ECC, unbuffered DDR-400/DDR
333, two-way interleaved or non-interleaved SDRAM. See Section 2-4 for details
on installing memory.
Question: How do I update my BIOS?
Answer: It is recommended that you not upgrade your BIOS if you are not experi-
encing problems with your system. Updated BIOS fi les are located on our web site
at http://www.supermicro.com/techsupport/BIOS/bios.htm. Please check our BIOS
warning message and the information on how to update your BIOS on our web site.
Also, check the current BIOS revision and make sure it is newer than your current
BIOS before downloading. Select your mainboard model and download the BIOS
fi le to your computer. Unzip the BIOS update fi le and you will fi nd the readme.txt
(fl ash instructions), the awdfl ash.exe (BIOS fl ash utility) and the BIOS image (xxxx.
bin) fi les. Copy these fi les onto a bootable fl oppy and reboot your system. Then,
follow the readme.txt to fl ash the BIOS.
Question: After fl ashing the BIOS my system does not have video. How can
I correct this?
Answer: If the system does not have video after fl ashing your new BIOS, it indicates
that the fl ashing procedure failed. To fi x this, fi rst clear CMOS per the instructions
in this manual and retry the BIOS fl ashing procedure. If you still do not have video,
please use the following BIOS Recovery Procedure. First, make sure the JPWAKE
jumper is disabled. Then, turn your system off and place the fl oppy disk with the
saved BIOS image fi le (see above FAQ) in drive A. Press and hold <Alt> and <F2>
3-3
P8SGA User's Manual
at the same time, then turn on the power keeping these keys pressed until your
fl oppy drive starts reading. Your screen will remain blank until the BIOS program
is done. If the system reboots correctly, then the recovery was successful. The
BIOS Recovery Procedure will not update the boot block in your BIOS.
Question: What's on the CD that came with my motherboard?
Answer: The supplied compact disc has quite a few drivers and programs that will
greatly enhance your system. We recommend that you review the CD and install the
applications you need. Applications on the CD include chipset drivers for Windows
and security and audio drivers.
Question: Why can't I turn off the power using the momentary power on/off
switch?
Answer: The instant power off function is controlled in BIOS by the Power But-
ton Mode setting. When the On/Off feature is enabled, the motherboard will have
instant off capabilities as long as the BIOS has control of the system. When the
Standby or Suspend feature is enabled or when the BIOS is not in control such
as during memory count (the fi rst screen that appears when the system is turned
on), the momentary on/off switch must be held for more than four seconds to shut
down the system. This feature is required to implement the ACPI features on the
motherboard.
Question: How do I utilize the six-channel sound?
Answer: The six-channel sound available on the P8SGA can be enabled with the
audio driver software that was included in your motherboard package. When acti-
vated, sound will be routed through the jacks under the Game Port as follows: Line
Out = front L&R speakers, Line In = rear L&R speakers, MIC = center and subwoofer
speakers. You must also enable the "AC97 Audio" setting in the Advanced Chipset
section of the BIOS setup.
Question: I installed my microphone correctly but I can't record any sound.
What should I do?
Answer: Go to <Start>, <Programs>, <Accessories>, <Entertainment> and then
<Volume Control>. Under the Properties tab, scroll down the list of devices in the
menu and check the box beside "Microphone".
Question: How do I connect the ATA100/66 cable to my IDE device(s)?
Answer: The 80-wire/40-pin high-density ATA100/66 IDE cable that came with
your system has two connectors to support two drives. This special cable must be
used to take advantage of the speed the ATA100/66 technology offers. Connect
the blue connector to the onboard IDE header and the other connector(s) to
your hard drive(s). Consult the documentation that came with your disk drive for
details on actual jumper locations and settings.
3-4
Chapter 3: Troubleshooting
Question: After I have installed 4 pieces of 1GB Memory, why does the BIOS
only detect about 3.145 GB of memory during POST?
Answer: Because the chipset does not support memory remapping, and PCI-e
memory requires a great deal of memory, so there is a memory hole located around
the 4GB memory address.
Question: I have already enabled the USB Wake-Up mode in the BIOS, my
system still cannot enter "Standby Mode"? Why?
Answer: When USB Wake-Up is enabled, be sure to unplug the USB devices on
the Front Panel USB ports (-USB 7/8) before entering Standby Mode.

BIOS
4-1 Introduction
This chapter describes the AwardBIOS for the P8SGA. The Award ROM BIOS
is stored in a Flash chip and can be easily upgraded using a fl oppy disk-based
program.
Note: Due to periodic changes to the BIOS, some settings may have been added
or deleted and might not yet be recorded in this manual. Refer to the Manual
Download area of our web site for any changes to BIOS that are not refl ected in
this manual.
System BIOS
The BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®, and
PS/2® compatible computers. The AwardBIOS Flash chip stores the system pa-
rameters, such as amount of memory, type of disk drives and video displays, etc.
CMOS requires very little power. When the computer is turned off, a back-up battery
provides power to the BIOS Flash chip, enabling it to retain the system parameters.
Each time the computer is powered-on, the computer is then confi gured with the
values stored in the BIOS ROM by the system BIOS, which gains control when the
computer is powered on.
How To Change the Confi guration Data
The CMOS information that determines the system parameters may be changed
by entering the BIOS Setup utility. This Setup utility can be accessed by pressing
<Del> at the appropriate time during system boot.
Starting the Setup Utility
Normally, the only visible POST (Power On Self Test) routine is the memory test. As
the memory is being tested, press the <Delete> key to enter the main menu of the
BIOS Setup utility. From the main menu, you can access the other setup screens,
such as the Chipset and Power menus. Section 4-3 gives detailed descriptions of
each parameter setting in the Setup utility.
