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 system 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/Product_page/product-m.htm) for updates on sup-

ported processors. This product is intended to be professionally installed.

1-2 Chipset Overview

Intel’s Grantsdale (915G) chipset, is comprised of 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-processor desktop solutions.

Graphics Memory Controller Hub (GMCH)

The function of the GMCH 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 GMCH is optimized for the Prescott proces-

sors in an LGA775 Package. It supports one or two channels of unbuf-

fered, 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 to ensure that system interfaces operate efficiently. The Direct

Media Interface (DMI) is a point-to-point interconnect 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 deliver-

ing 3D, 2D and video capabilities. It also provides interfaces to a progres-

sive 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 motherboard has an onboard System Hardware Monitor chip that sup-

ports 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 sensi-

tivity 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 warning

function in the BIOS. This allows the user to define an overheat tempera-

ture. 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.

Chapter 1: Introduction

1-11

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.

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.

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.

1-12

P8SGA User’s Manual

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 recommended.

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 configura-

tions. In areas where noisy power transmission is present, you may

choose to install a line filter to shield the computer from noise. It is recom-

mended that you also install a power surge protector to help avoid problems

caused by power surges.

Chapter 1: Introduction

1-13

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 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-

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 support ACPI and APM (Ad-

vanced Power Management).
