Chapter 1: Introduction

1-2 Chipset Overview

Intel’s 845G chipset (P4SGA) is made up of two primary components: the

Graphics Memory Controller Hub (GMCH) and the I/O Controller Hub (ICH4).

The 845GL (P4SGL) and 845GE (P4SGR/P4SGE) chipsets also include these

components, however the 845GL provides no AGP support and only a 400

MHz system bus speed and the 845GE supports faster memory.

Graphics Memory Controller Hub (GMCH)

The GMCH includes the host (CPU) interface, memory interface, ICH4 inter-

face and 4xAGP interface for the 845G/GL/GE chipset. It contains ad-

vanced power management logic and supports a single channel of DDR

SDRAM. The AGP 2.0 interface supports 4x data transfers and operates at

a peak bandwidth of 1.6 GB/s.

An external graphics accelerator card is not required due to the integrated

graphics in the 845G/GL/GE chipset. (If the system BIOS detects an exter-

nal AGP device, it will disable the integrated graphics.) The integrated

graphics controller delivers 3D, 2D and video capabilities, including video

conferencing applications. The controller does not utlilize local memory, but

accesses graphics data located in system memory at speeds matching that

of the SDRAM installed. It also includes a cache controller to avoid frequent

memory fetches of recently accessed texture data.

I/O Controller Hub (ICH4)

The ICH4 is a fourth-generation I/O Controller Hub subsystem that integrates

many of the input/output functions of the chipset, including a two-channel

ATA100 Bus Master IDE controller. The ICH4 also interfaces with the PCI

cards, the AC'97 Audio CODEC and the various communications ports.

Nearly all communications between the GMCH and the ICH4 takes place

over the hub Interface, which is a 66 MHz/266 MB/s bus.

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 hit the

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.

SUPER P4SGA/P4SGL/P4SGR/P4SGE User’s Manual

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER

P4SGA/P4SGL/P4SGR/P4SGE. The motherboard has an onboard System

Hardware Monitor chip that supports PC health monitoring.

Nine Onboard Voltage Monitors for the CPU Core, Chipset
Voltage, +3.3V, +3.3V standby,

++

++

+5V, +5V standby, 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 sensi-

tivity 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 fans are controlled by the power management functions.

Environmental Temperature Control

The P4SGA/P4SGL/P4SGR/P4SGE has a CPU "thermal trip" feature. A ther-

mal control sensor monitors the CPU temperature in real time and will send

a signal to shut down the system whenever the CPU temperature exceeds

a certain threshold. This works to protect the CPU from being damaged by

overheating.

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, the CPU thermal trip feature will

activate and shut down the system.

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 in-

fecting the BIOS area and destroying valuable data.

Auto-Switching Voltage Regulator for the CPU Core

The 3-phase-switching voltage regulator for the CPU core can support up to

60A current and auto-sense voltage IDs ranging from 1.1V to 1.85V. This

will allow the regulator to run cooler and thus make the system more stable.

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.

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 keyboard will

function like a normal keyboard during system boot-up.

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

1-16

SUPER P4SGA/P4SGL/P4SGR/P4SGE User’s Manual

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.

Wake-On-Ring 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.

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

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.

Chapter 1: Introduction

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 SUPER P4SGA/P4SGL/P4SGR/P4SGE accommodates 12V ATX power

supplies. Although most power supplies generally meet the specifications

required by the CPU, some are inadequate. You power supply must supply

1 amp of 5V standby voltage.

It is strongly recommended that you use a high quality power supply that

meets 12V ATX power supply Specification 1.1 or above. Additionally, in

areas where noisy power transmission is present, you may choose to in-

stall 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.

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-

figuration and Power Interface), which includes support of legacy and ACPI

power management through a 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 be flexibly

adjusted to meet ISA PnP requirements, which suppport ACPI and APM (Ad-

vanced Power Management).

1-18

SUPER P4SGA/P4SGL/P4SGR/P4SGE User’s Manual

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 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 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.

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 anti-

static bag.

• Handle the board by its edges only; do not touch its components, periph-

eral 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 ex-

cellent conductivity between the power supply, the case, the mounting

fasteners and the motherboard.

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 for full installation of 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 and add-on cards.

4. Finally, connect the cables and install the drivers.

2-2

SUPER P4SGA/P4SGL/P4SGR/P4SGE User's Manual

IMPORTANT: Always connect the power cord last and always remove it

before adding, removing or changing any hardware components. Make

sure that you install the processor into the CPU socket before you install the

CPU heatsink.

!

2-2 Processor and Heatsink Fan Installation

When handling the processor package, avoid placing

direct pressure on the label area of the fan.

Installation of the Processor and Heatsink

1. Locate the following components, which are included in the shipping

package.

Bracket (1)

Clips (2)

2. Insert the white pegs into the black an-

chors. Do not force the white pegs all the

way in - about 1/3 of the white pegs should

be inside the black anchors. (These are for

chassis that do not have four CPU retention

holes.)

3. Place a retention bracket in the proper position

and secure it by pressing two pegs into the reten-

tion holes until you hear a *click*. The clicking

sound indicates that the peg is locked and secured.

2-3 Mounting the Motherboard in the Chassis

All motherboards have standard mounting holes to fit different types of

chassis. Make sure the location of all the mounting holes for both the

motherboard and the chassis match. Although a chassis may have both

plastic and metal mounting fasteners, metal ones are highly recommended

because they ground the motherboard to the chassis. Make sure the metal

standoffs click in or are screwed in tightly. Then use a screwdriver to

secure the motherboard onto the motherboard tray.

and AGP Connections

Use the following information to connect the floppy and hard disk drive

cables.

• The floppy disk drive cable has seven twisted wires.

• A red mark on a wire typically designates the location of pin 1.

• A single floppy disk drive ribbon cable has 34 wires and two connectors to

provide for two floppy 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 inter-

face and the other connector(s) to your hard drive(s). Consult the docu-

mentation that came with your disk drive for details on actual jumper

locations and settings for the hard disk drive.

If you are a system integrator, VAR or OEM, a POST diagnos-

tics card is recommended. For I/O port 80h codes, refer to

App. B.

Memory Errors

1. Make sure the DIMM modules are properly and fully installed.

2. You should be using unbuffered DDR memory (see next page). Also, it

is recommended that you use the same memory speed for all DIMMs

in the system. See Section 2-4 for memory limitations.

3. Check for bad DIMM modules or slots by swapping modules between

slots and noting the results.

4. Check the power supply voltage 115V/230V switch.

Losing the System’s Setup Configuration

1. Ensure that you are using a high quality power supply. A poor quality

power supply may cause the system to lose the CMOS setup

information. Refer to Section 1-6 for details on recommended power

supplies.

2. The battery on your motherboard may be old. Check to verify that it

still supplies ~3VDC. If it does not, replace it with a new one.

3-3 Frequently Asked Questions

Question: What are the various types of memory that my mother-

board can support?

Answer: The P4SGA/P4SGL supports up to 2 GB of non-ECC unbuffered

DDR-200 (PC1600) or DDR-266 (PC2100) type SDRAM. The P4SGR/P4SGE

supports up to 2 GB of non-ECC unbuffered DDR-266 (PC2100) or DDR-

333 (PC2700) type SDRAM. Important: See Section 2-4 on rules to ob-

serve when installing DDR memory modules.

Question: How do I update my BIOS?

Answer: It is recommended that you not upgrade your BIOS if you are not

experiencing problems with your system. Updated BIOS files 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 file to your computer.

Unzip the BIOS update file and you will find the readme.txt (flash instruc-

tions), the awdflash.exe (BIOS flash utility) and the BIOS image (xxxx.bin)

files. Copy these files onto a bootable floppy and reboot your system. It is

not necessary to set the BIOS boot block protection jumpers on the

mainboard. At the DOS prompt upon rebooting, enter the command

"awdflash." Then type in the BIOS file that you want to update (xxxx.bin).

SUPER P4SGA/P4SGL/P4SGR/P4SGE User's Manual

Question: After flashing the BIOS my system does not have video.

How can I correct this?

Answer: If the system does not have video after flashing your new BIOS,

it indicates that the flashing procedure failed. To fix this, first clear CMOS

per the instructions in this manual and retry the BIOS flashing procedure. If

you still do not have video, please use the following BIOS Recovery Pro-

cedure. First, make sure the JPWAKE jumper is disabled. Then, turn your

system off and place the floppy disk with the saved BIOS image file (see

above FAQ) in drive A. Press and hold <Alt> and <F2> at the same time,

then turn on the power keeping these keys pressed until your floppy 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

Button 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 first 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: Six-channel sound is only available on the P4SGA/P4SGL. Enable

it through the audio driver software that was included in your motherboard

package. When activated, 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 see some of my PCI devices sharing IRQs, but the sys-

tem seems to be fine. Is this correct or not?

Answer: Some PCI Bus Mastering devices can share IRQs without perfor-

mance penalties. These devices are designed to work correctly while shar-

ing IRQs. See Table 3-1, below, for details on shared IRQs.

* Assumes USB 2.0 drivers have not been installed.

** Since the P4SGR/P4SGE only have five PCI slots, the USB 2.0 controller

has its own dedicated IRQ.

Table 3-1. P4SGA/P4SGL/P4SGR/P4SGE IRQs

PCI 1 shares an IRQ with AC97 and the System Management bus

PCI 2 shares an IRQ with a USB 1.1 controller (USB4 & USB5)*

PCI 3 shares an IRQ with a USB 1.1 controller (USB2 & USB3)*

PCI 4 has a dedicated IRQ (does not share)

PCI 5 has a dedicated IRQ (does not share)

PCI 6 shares an IRQ with the USB 2.0 controller (USB0 - USB5)**

Question: I installed my microphone correctly but I can't record any

sound (P4SGA/P4SGL). 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 technol-

ogy offers. Connect the blue connector to the onboard IDE header

and the other connector(s) to your hard drive(s). Consult the docu-

mentation that came with your disk drive for details on actual jumper loca-

tions and settings.

Chapter 4

AwardBIOS

4-1 Introduction

This chapter describes the AwardBIOS for the P4SGA/P4SGL/P4SGR/

P4SGE. The Award ROM BIOS is stored in a Flash chip and can be easily

upgraded using a floppy 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 reflected 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 parameters, 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 pow-

ered-on, the computer is then configured with the values stored in the BIOS

ROM by the system BIOS, which gains control when the computer is pow-

ered on.

How To Change the Configuration Data

The CMOS information that determines the system parameters may be

changed by entering the BIOS Setup utility. This Setup utility can be ac-

cessed 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.
