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 SUPER P4SCA/P4SCE motherboard. The P4SCA/P4SCE supports

single Intel Pentium

®

4 processors or Intel Celeron processors up to 3.06

GHz (with Hyper Threading) at a system bus speed of 800/533/400

MHz.(*see the note below). Pentium 4/ Celeron processors are housed in a

478-pin micro PGA (Plastic Grid Array) package. Please refer to the moth-

erboard specifications pages on our web site (http://www.supermicro.com/

Products/motherboard) for updates on supported processors. This product

is intended to be professionally installed.

*Note: Please use the CPU that supports 0.13 Micron Manufacturing Tech-

nology.

Manual Organization

Chapter 1 includes a checklist of what should be included in your

mainboard box, describes the features, specifications and performance of

the P4SCA/P4SCE mainboard and provides detailed information about the

chipset.

Chapter 2 begins with instructions on handling static-sensitive devices.

Read this chapter when installing the processor and DDR memory modules

and when mounting the mainboard in the chassis. Also refer to this chapter

to connect the floppy and hard disk drives, the IDE interfaces, the parallel

and serial ports, the mouse and keyboard and the twisted wires for the

power supply, the reset button, the keylock/power LED and the speaker.It

also details the installation of Intel ICH5R SATA RAID Utility and other soft-

ware programs.

If you encounter any problems, see Chapter 3, which describes trouble-

shooting procedures for the video, the memory and the setup configuration

stored in the CMOS. For quick reference, a general FAQ (Frequently Asked

Questions) section is provided. Instructions are also included for contact-

ing technical support. In addition, you can visit our web site at

www.supermicro.com/products/motherboard/ for more detailed information.

Chapter 4 includes an introduction to BIOS and provides detailed informa-

tion on running the CMOS Setup utility.

Appendix A provides BIOS POST Messages.

Appendix B lists BIOS POST Codes.

Appendix C Installing the Operating System and Software Programs.

1-2 Chipset Overview (Intel's E7210 Canterwood

Chipset)

The E7210 Canterwood Chipset contains the following main components:

the E7210 Canterwood Memory Controller Hub (MCH) and the I/O Controller

Hub 5(ICH5R). These two components are interconnected via Hub Inter-

face.

Memory Controller Hub (MCH)

The E7210 Canterwood Memory Controller Hub (MCH) is designed to sup-

port Intel PGA 478-pin Processors. The function of the E7210 Canterwood

MCH is to arbitrate the flow of data transfer between system bus (FSB),

system memory, and Hub Interface. The Canterwood MCH supports 800

MHz FSB, 400/333 Memory Interface, 533 MHz FSB, 333/266 Memory Inter-

face, and 400 MHz FSB 266 MHz Memory Interface.

System Memory Interface

The E7210 Canterwood Memory Controller (MCH) supports two 64-bit wide

DDR data channels with bandwidth up to 6.4 GB/s (DDR400) in dual channel

mode. It supports 128-Mb, 256-Mb,512-Mb, x8, X16 DDR. Maximum system

memory supports up to 4.0 GB for Dual-Channel. ECC/Non ECC unbuffered

DDR DIMMs are supported, but it does not support registered, mixed-mode

DIMMs.

Intel ICH5R System Features

The 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 Control-

ler, two Serial ATA (SATA) Host Controllers, SMBus 2.0 Controller, LPC/

Flash BIOS Interface, PCI 2.3 Interface, and Integrated System Management

Controller.

SUPER P4SCA/P4SCE User’s Manual

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER

P4SCA/P4SCE. The motherboard has an onboard System Hardware Monitor

chip that supports PC health monitoring.

Eight Onboard Voltage Monitors for the CPU Core, +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, using Super Micro's Monitoring Software-Super O Doctor.

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 P4SCA/P4SCE has a CPU "thermal trip" feature. A thermal control sen-

sor monitors the CPU temperature in real time and will send a signal to shut

down the system whenever the CPU temperature exceeds a certain thresh-

old. 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 Super Micro. This feature can prevent viruses from

infecting the BIOS area and destroying valuable data.
