System Board

The system board contains most of the components that provide system functions. The following subsections provide a description of these components.

Processor

The system board uses a 350-MHz, 400-MHz, or 450-MHz Intel Pentium II processor or a 500-MHz Intel Pentium III processor. All use MMX technology. The MMX processor improves audio, video, and 3D graphics performance.

Each processor is packaged in a Single Edge Contact (SEC) cartridge that plugs into the system board’s slot 1.

System Cache/Memory

To use the processor’s power, the system features an optimized 64-bit memory interface and provides support for a second level cache to complement the processor’s internal cache.

High-performance features include:

Tpipeline 32-bit addressing

T64-bit data

T512-KB of pipeline burst secondary cache; direct mapped write-back and write-through organization.

The system comes with 32 to 384 MB of main system memory. Three sockets on the system board support up to 384 MB of high-speed memory using industry-standard gold-plated dual in-line memory modules (DIMMs).

The system supports PC100-MHz Synchronous DRAM (SDRAM) only.

Technical Information 1-5

The system supports the following DIMM configurations:

T4-Mbit by 64 (32-MB DIMM)

T8-Mbit by 64 (64-MB DIMM)

T16-Mbit by 64 (128-MB DIMM).

Chipset

The Intel 440BX chipset provides DMA, memory, and bus control. The chipset includes the following chips:

TIntel 82443BX PCI/AGP (PAC) ¾ provides bus-control signals, address paths, and data paths for transfers between the processor’s host bus, PCI bus, Accelerated Graphics Port (AGP), and main memory.

TIntel 82371EB PCI ISA IDE Xcelerator (PIIX4E) ¾ implements the PCI-to-ISA bridge, PCI IDE functionality, Universal Serial Bus (USB) host/hub functions, and enhanced power management.

PCI Local Bus

The 32-bit industry-standard PCI bus is a highly-integrated input/output (I/O) interface that offers the highest performance local bus available for the Pentium II processor. The PCI bus supports burst modes that send large chunks of data across the bus, allowing fast displays of high-resolution images.

The high-bandwidth PCI local bus eliminates data bottlenecks found in traditional systems, maintains maximum performance at high clock speeds, and provides a clear upgrade path to future technologies.

The PCI bus contains two embedded PCI devices: the PCI local bus IDE interface and the PCI video/graphics controller. The PCI bus also contains a connector for attaching the bus expansion board.

Expansion Bus

The expansion bus contains one ISA slot, three PCI slots, one PCI/ISA slot, and one AGP video slot. The PCI ISA IDE Xcelerator chip (PIIX4E) provides the logic that enables the ISA bus functions. With 24-bit memory addressing, a 16-bit data path, and an 8-MHz clock, the ISA bus is designed to support all peripherals compatible with the IBM® AT™ standard. For PCI functions, the Xcelerator chip provides 32-bit memory addressing, 32-bit data path, and a 33-MHz clock speed.

BIOS

The BIOS (Basic Input Output System) is stored in the Flash EPROM. The Flash EPROM is reprogrammable and allows fast, economical BIOS upgrades.

The system memory map is shown in the following table.

1-6 Technical Information

System Memory Map

Memory Address	Size	Function

E0000-E7FFF	32 KB	System BIOS (available as
		UMB)
C8000-DFFFF	96 KB	Available high DOS memory
		(open to ISA and PCI bus)
A0000-C7FFF	160 KB	Video memory and BIOS
00000-9FFFF	640 KB	Conventional memory

Plug and Play Support

The system comes with Plug and Play BIOS technology. Plug and Play eliminates complicated setup procedures for installing Plug and Play expansion boards.

To add a Plug and Play expansion board, simply power off the system, install the board, and power on the system. There are no jumpers to set and no system resource conflicts to resolve. Plug and Play automatically configures the board for the system. The system also supports non-Plug and Play boards.

Plug and Play is controlled by the Plug and Play BIOS and the system’s operating system. The Plug and Play BIOS is stored in the Flash EPROM on the system board.

The Plug and Play BIOS adds several steps to the POST process. During POST, the Plug and Play evaluates the configuration of installed boards and assigns available system resources to the devices. On completion of Plug and Play POST, the operating system checks to see if there are any additional resources required, then assigns available resources to the devices.

CMOS Memory/Real-Time Clock Battery

The 82371EB PCI ISA IDE Xcelerator (PIIX4E) on the system board stores system information in non-volatile CMOS memory. The chip also contains the system’s real-time clock. Both are maintained by a 3-volt coin cell lithium battery on the system board. The battery is replaceable.

DMA/IRQ Settings

The system automatically configures, with minimal user intervention, interrupt requests (IRQ), direct memory access (DMA) channels, and other parameters when adding PCI boards.

The following tables list system IRQ and DMA default settings.

1-8 Technical Information

IDE Ports

The system board provides two fast IDE ports: primary channel and secondary channel.

Each port supports two devices for a total of four IDE devices. The system board allows the connection of an IDE CD-ROM drive for system configuration flexibility without the addition of a controller.

The IDE ports feature an enhanced IDE interface which supports up to 16.7 MB per second 32-bit wide data transfers on the high-performance PCI local bus. The standard hard drive and Zip® drive (in some systems) are connected to the primary channel. The CD-ROM drive is attached to the secondary channel.

I/O Ports

The system board features an enhanced parallel port, two buffered high-speed serial ports, and two Universal Serial Bus (USB) ports.

The enhanced parallel port supports Enhanced Capabilities Port (ECP) and Enhanced Parallel Port (EPP) modes for devices that require ECP or EPP protocols. These protocols allow high-speed bi-directional transfer over a parallel port and increase parallel port functionality by supporting more devices.

The two buffered high-speed serial ports use a fast 16C550 UART which supports transfer rates up to 115.2 kilobits (Kb) per second. These ports allow the installation of high-speed serial devices for faster data transfer rates.

The two USB ports allow additional new plug and play serial devices without removing the system cover. Simply plug the USB device into the port. The speed varies between 12 megabits per second (Mbps) for printers and 1.5 Mbps for mice and keyboards. Up to 127 USB devices can be connected to the computer.

The combination of the enhanced parallel port, buffered serial ports, and USB ports ensure optimum performance for future peripheral devices and operating systems.

1-10 Technical Information

Power Management

The Advanced Power Management (APM) program, located on the 82371EB PCI ISA IDE Xcelerator (PIIX4E) chip, reduces system power consumption when there is no activity detected from the keyboard, mouse, diskette drive, CD-ROM/DVD drive, or hard drive after a predefined period of time. As soon as activity is detected, the system resumes where it left off.

In the CMOS Setup utility, an inactivity timer is available for setting the length of time before the system enters a low-power mode.

This section provides information on configuring the computer. The section includes information on the

TBIOS Setup Utility for configuring the system

TIntel Processor Serial Number Control utility for enabling or disabling the Pentium III processor serial number (for Pentium III based systems only).

BIOS Setup Utility

The BIOS Setup utility is used to configure the main components of the computer. The system ships from the factory with the correct system parameters for the configuration. Unless adding optional hardware, it’s usually not necessary to run the BIOS Setup utility. However, it might be necessary to run the BIOS utility to set features that customize the system, such as setting the time and date or setting security features.

System configuration information is stored in nonvolatile memory. A nonvolatile memory device retains its data when system power is turned off. Nonvolatile memory is a complementary metal-oxide semiconductor (CMOS) chip backed up by a battery on the system board. The battery supplies continuous power to CMOS memory and maintains configuration information when system power is off.

When to Use Setup

The Setup utility allows the user to view and set system parameters. Use the Setup utility program to:

Tset the time and date.

Tupdate or check system parameters when adding or removing expansion options.

Tchange or set power management features.

Tcorrect a hardware discrepancy when the Power-On Self-Test (POST) displays an error message and a prompt to run Setup.

Tcheck the installation of optional memory by comparing the amount of memory installed with the amount of memory displayed by Setup.

Tchange certain system operating parameters, such as boot device sequence and keyboard parameters.

Tconfigure system connections for peripherals such as the diskette drive, hard drives, and devices connected to the printer port and serial port.

Tcustomize the system with security features such as passwords.

Tset system parameters after replacing the CMOS battery.
