The AMI BIOS Setup utility program is used to configure the main components of the computer.

The computer ships fro m the factory with the correct system parameter s for t he configuration. Unless optional hardware is added, it’s not necessary to run the BIO S Setup utilit y to o perate t he syst em. Howe ver, the Se tup utility shou ld be run to set features that customize the syst em, such as security features.

System configuration information is stored in a nonvolatile memory device. The device re ta ins its da ta w he n system power is tu rned off. Nonvolatile memory is stored in a complement ary metal-oxide semico nduct or (CMOS) memory chip backed up by a battery on the system board. The battery supplies cont inuous power to CMOS memory and maintains configuration information when system power is off (see “Battery Replacement” in Section 3).

NEC CSD recommends that the current BIOS Setup parameters be printed out or written down and the informat ion stored in a safe place. This lets you restore the system to the current parameters if replacing the battery.

Intel Processor Serial Number Control Utility

The Intel Processor Serial Number Control utility is a Windows program that enables or disables the read ing of the Pentium III pro cessor serial number by software. This function lets you control which software programs or websites have permission to r ead the processor serial number. When installed, the utility runs automat ically each t ime the system powers on.

Note

: The Intel Processor Serial Number Control Utility is for use with systems shippi ng with the Intel Pentium III processor. Instal ling this utility on a system which does not contain a Penti um III processor gener ates an error message.

This utility places an icon in the Windows s yst em tray. The icon provides a visual status of the processor serial number. You have the option of hiding the system tray icon. Yo u can disable t he processor serial number at any time. However, enabling the seria l number r equires restarting the syst em.

Processor Serial Number

The Int e l processor serial number, a new feature of the Pentium III processor, is an identifier for the processor. The processor ser ial number is desig ned t o be unique, and when used in conjunction with other identification methods, can be used to identify the system or user. This number can be used in a wide variety of applications which be nef it from stronger forms o f system and user identificat ion.

The processo r seria l number is analogous to a co nventional serial number, with these important differences:



A software application can read the processor serial number.

You can disable the reading of the serial number via ut ility progr ams

FAQs

What are the benefits of the processor serial number?

www.intel.com/pentiumiii

You can use the processo r serial number in applications which benefit from stronger forms of system and user identification.

Why would I want to turn off my processor serial number?

Intel believes the processor serial number can provide compelling benefits to users. They are developing featur es in conjunction with the processo r ser ial number to allow responsib le service providers to prov ide services w hic h maintain your privacy. However, if you are concerned that a given application/ service using your pro cessor numbe r might impact your privacy, yo u can turn off the processor serial number using the utility.

What is the default state of the processor serial number?

The default state of the processor serial number is o n, unt il the Pro cessor Serial Numbe r Co ntro l utility is installed. Once the Processor Serial Number Contro l ut ility is installed, it tur ns the pr oces sor s e rial nu mber off by d efault. Y ou can use the utility to turn on the processor serial number.

Can a website read my serial number without my knowledge?

No , gener ally not. Websites c anno t r e ad serial number s unle ss you a llow t hem to download a program which can read t he processor serial number. Almost all browsers are configured to war n users whenever t he y download executable software. Unless you disable the warning in the browser, you should receive a notification.

2-30 System Configuration

Does Intel track serial numbers?

Generally not, other than related to the manufacturing process. Intel does not, in the absences of advance and express consent of a user, collect seria l number data which is otherwise identified with a user.

Which programs and/or websites currently use the processor serial number?

You can find a complete list of programs which can take advantage of the processor serial number and other new capabilities of the Pentium III processo r at

http://www.intel.com/pentiumiii/utility.htm

How can I tell if my processor serial number is turned on?

The vast majority of Pentium III processor-based systems ship with the processo r serial number ena bled. T he co nt rol utility allows you to check the status by:



Viewing the icon itself. The disabled icon shows a red circle wit h a

white “x.”

Proc essor and Secondary Cache

The system uses an I ntel Celeron, Pentium II, or Pentium III processor with an internal clock speed of 300 MHz, 333 MHz, 350 MHz, 366 MHz, 400 MHz, 433 MHz, 450 MHz, or 500 MHz (depending on type of pr ocessor and model).

The processor is an advanced pipelined 32-bit addressing, 64-bit data processor des igned to o ptimize multitas king ope rating systems. The 64 -bit registers and data paths support 64-bit addresses and data types.

To use the processor ’s po wer, the syste m features an optimized 64-bit memory interface and 512 KB (128 KB for Celeron) of secondary write-back cache on the processor.

The processor is compatible with 8-, 16-, and 32-bit software written for the Intel386™, Intel486™, Pentium, and Pentium Pro processors. The processor is mounted in S.E.C. cartridge with an att aching heats ink that insta lls as a unit in Slot 1 on the system board.

System BIOS

The ISA- and PCI-compatible BIOS is conta ined in a flash memory device on the system board. The BIOS pro v ides t he Power - On Self-Test (POST), the system Setup program, a PCI and IDE auto-configur ation utility, and BIOS recovery code.

The system BIOS is always shado wed. S hado wing allows a ny BIOS routine to be executed from fast 32-bit DRAM on t he syst em board, instead of from the slower 8-bit flash device.

The Flash ROM allows fast, economical BIOS upgrades. The Flash ROM is a reprogrammable EPROM containing both the system and video BIOS. Using the Flash ROM to change the ROM BIOS pro v ides the fo llowing ad va nt ages:



the BIOS upgrade is performed quickly and easily



the expense of replacing ROM BI OS chips is e liminat ed, so system

maintenance co sts are reduced



there is less chance o f inadvert ently damaging the system board than

when physically replacing ROMs



new technology can be incorporated while maintaining corporat e

standards



network administrators can exercise company-w ide co nt ro l of BIOS

revisions.

The BIOS programs execute t he Power - On Se lf-Test , initialize processo r controllers, and interact with the display, diskett e dr ive, hard dr ives, communication devices, and peripherals. The system BIOS also contains the Setup utility. The PO ST copies the RO M B IOS into RAM (shadow ing) for maximum performance.

4-12 System Board

The Flash ROM allows the system and video BIOS to be upgraded with the BIOS Update utility, without having to physically remove the ROM (see Section 2 for further informat ion on the BIOS U pdate util ity). The Flash R OM supports the reprogramming of the system BIOS and the video BIOS.

System Memory

The system comes with between 32 MB and 256 MB o f SDRAM installed in DIMM sockets on the syste m board .

The memory configuration consists of two sockets. The DIMM so ckets accept 168-pin, 64-bit (non-ECC) 16-, 32-, 64-, and 128-MB DIMMs. See “DIMM Sockets” for a list of supported DI MMs.

Plug and Play

The system comes with a Plug and Play BIOS in support of Plug and Play technology. Plug and Play simplifies setup procedures for installing Plug and Play expansion boards. With Plug and Play, adding a Plug a nd P lay expansion board is done by turning off the system, installing the board, and turning on the system. There are no jumpers t o set and no system resource co nflict s t o resolve. Plug and Play automatically configures the board. (Some Plug and Play devices

may need to be jumpered if used in a system running the Windows NT operating system.)



ISA Bus

The system boar d uses the IS A bus for transfer ring data between the processor and some I/O peripherals and expansion boards. The ISA bus supports 16-bit data transfers and typicall y operates at 8 MHz.

PCI Local Bus

The 32-bit PCI local bus is the primary I/O bus for t he system. The PCI bus is a highly integrated I/O interface t hat o ffers the highest per for mance loca l bus available for the Celeron or Pentium processor. The bus supports burst modes that send large amounts of data across the bus, a llow ing fast disp la ys o f highresolution images.

The PCI local bus is a high-per formance bus that provides a processo rindependent data path between the CPU and high-speed peripherals. The PCI bus is a robust inter connect mechanism designed specifically to accommodate multiple high performance peripherals for graphics and full mo tion video.

The PCI local bus supports memory transfer rates of over 100 MB per second for reads and over 120 MB per second for writes, depending on processor configuration.

System Board 4-13

PCI/IDE Ports

The system board supports two high-performance PCI/IDE ports: a primary port and a secondary port on the system board. Each port supports up to two devices for a total of four IDE devices. The primary PCI/IDE port has an enhanced IDE interface that supports PIO Mode 4 devices with 16 MB per second 32-bit wide data transfers on t he high-performance PCI local bus. Each port suppo rts Ultra DMA/33.

The installed hard drive is connected to the primary PCI/IDE connector with a three-co nnecto r cable. I f a CD-ROM dr ive is included in the syst em, it is connected to the seco ndary PCI/IDE port with a three-connector cable. A second device can be added to the primary PCI/IDE port.

Parallel Interface

The system has a 25-pin bidirectional parallel port o n the system board. Po rt specifications co nform to the IBM-PC standards. The po rt supports Enhanced Capabilities Port (ECP) and Enhanced Parallel Port (EPP) modes for devices that require ECP or EPP protocols. The protocols allow high-speed bidirectional transfer over a par allel port and increase para lle l port functionality by supporting more devices.

The BIOS has automat ic ISA printer port sensing t hat wo r ks with most devices. If the BIOS detects an ISA printer port mapped to the same address, the built-in printer port is disabled. (Verify in the BIOS Setup that printer ports mapped to the same address are enabled or disabled appro pr iately.) The BIOS also sets the first parallel interface po rt it finds as LPT1 and the second port it finds as LPT2. The interrupt is set at IRQ7 via the BIOS Set up ut ility. So ftwar e- selectable base addresses are 228h, 378h, and 278h.

Sets of I/O addresses for the parallel port are given in the following table (see Section 2, “System Configuration, ” for inte rrupt levels). This is a list o f all possible configurations; the parallel port uses only one set.

Parallel Port Addresses

Starting I/O Address Port

378 LPT1 278 LPT2 228 LPT3 378 LPT1 278 LPT2

228 LPT3

Parallel interface sig nals are output through the syste m board’s 25-pin, D-subconnector . The co nnector is located at the back of the syste m unit.

4-14 System Board

Serial Interface

The system has two 16C550 UART compatible serial ports (COM1 and COM2) integrated on the I/O controller. The serial ports support the standard RS-232C interface. The buffered high-speed serial ports support transfer rates up to

115.2 KB. These ports allow the installation of high-s peed serial devices for faster dat a transfer rates.

Sets of I/O addresses for the two channels are given in the following table (see Section 2, “System Configuration,” for interrupt levels). Soft-selectable base addresses are 3F8h, 2F8h, 3E8h, and 2E8h.

See Section 2, “System Configuration,” for information on resetting the port through the BIOS Setup utility. See Section 9, “Specifications,” for the serial interface specifications.

Serial interface signa ls are output through the system board’s 9- pin, D-subconnector s. The connectors are located at the back of the system unit.

USB Interface

The Universal Serial Bus (USB) ports allo w new Plug and Play serial devices to be added without having to open the system. One USB device may be plugged into each USB port for direct system connect ion. With a hub and the proper cabling, up to 127 USB devices per port can be addressed by the syste m. The USB determines syst em resources for each per iphera l and ass ig ns t he m witho u t user intervention. Boot support for a USB keyboard is present so the system can be booted with a USB keyboard instead of a standard ke yboard.

Graphics Capabilities

The system supports AGP boards and PCI graphics boards. A PCI graphics board installs in one of the computer’s PCI expa nsion slots. An AGP board installs in t he system board’s AGP slot.
