System Board Features

Accelerated Graphics Port (AGP)

The AGP subsystem is dedicated for graphic-intensive applications. AGP is independent of the PCI bus and is intended for use with display adapters. AGP provides these performance features:

• Pipelined-memory read and write operations that hide memory access latency
• Demultiplexing of address and data on the bus for near 100 percent bus efficiency
• AC timing for 133 MHz data transfer rates (AGP), allowing data throughput of 533 MB/sec.

The integrated ATI RagePro Video accelerator is directly connected to the AGP Bus of the computer. No AGP expansion slot is available.

Battery

This external coin-style lithium battery (2032 style) supplies power to the integrated Real Time Clock (RTC) and CMOS memory. The battery has an estimated lifetime of three years and is easily replaced. When the computer is on, power is provided by the power supply to extend the life of the battery.

Danger of explosion if battery is incorrectly replaced.

Replace only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions.

DIMM sockets

The Dual Inline Memory Module (DIMM) socket, or bank, is a system board connection that holds one DIMM component. Two banks are available on the system board.

Memory Requirements

Any memory added to the computer must:

• Be 4-clock PC66- or 100-compliant 168-pin
• Be single- or double-sided
• Be a minimum of 8 MB of Synchronous Dynamic Random Access Memory, or SDRAM, expandable up to 512 MB of SDRAM (using 16, 64, or 128Mbit-based DRAM)
• Be built to an Intel 4clock 66MHz or 100MHz unbuffered SDRAM DIMM specification (runs at 66MHz)
• Contain a Serial Presence Detect (SPD) EEPROM that is programmed in compliance with Intel's PC SDRAM SPD specification, rev. 1.0 or 1.2A

Diskette drive controller

The diskette drive controller is compatible with the DP8473 and N82077 diskette drive controllers and supports both PC-AT and PS/2 modes. In the BIOS Setup utility, the diskette drive interface can be configured to support one diskette drive for the following capacities and sizes:

• 360K, 5.25-inch
• 1.2 MB, 5.25-inch
• 720K, 3.5-inch
• 1.2 MB, 3.5-inch (driver required)
• 1.25/1.44 MB, 3.5-inch
• 2.88 MB, 3.5-inch

Expansion slots and cards

The system board has the following expansion card slots:

• One ISA bus expansion slot (shared mechanically with the PCI slot)
• Three PCI expansion slots (one slot mechanically shared with the ISA slot)

Although there are four expansion slots, there is only enough room on the system board for three expansion cards. A PCI card slot and an ISA card slot are located next to each other, sharing an opening on the back of the computer case. Consequently, only one of these expansion slots can be used.

Fan connector

The power supply fan connector lets the system software control the fan, turning it off or on as needed. The fan connector is continuously supplied with power and is intended to be used for processor heat sinks with fans. The system does not control the power to connectors.

Flash ROM

This component serves as the storage area for the following items:

• The BIOS
• The BIOS Setup utility
• The Power-On Self Test (POST)
• The Update recovery code
• The PCI auto-configuration utility

IDE support

This system board has two independent high-performance bus mastering PCI IDE interfaces capable of supporting these devices:

• PIO Mode 3
• PIO Mode 4
• ATAPI
• Ultra ATA-33

The system supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector (ECHS) translation modes on both interfaces. The system automatically detects the IDE device transfer rate and the translation mode capability.

Intel 82371EB PCI set (PIIX4e)

This component provides the interface between the PCI and ISA buses and the following hardware controls:

• USB
• Ultra ATA-33
• Enhanced DMA
• Interrupt controller
• Power management
• Real-time clock

The PIIX4e also provides power management and RTC logic for the computer. The PIIX4e is a 324-pin BGA package.

Parallel port

The connector for the multimode bidirectional parallel port is a
25-pin D-Sub connector on the back panel. In the BIOS Setup utility, the parallel port can be configured to:

• Compatible (standard mode)
• Bidirectional (PS/2 compatible)
• Extended Parallel Port (EPP)
• Enhanced Capabilities Port (ECP)

Power connectors

This single-unit connector supplies power to the system board components and cooling fan. It is keyed to fit only one way.

Processor

The system board supports:

• One Pentium II or Celeron processors
• Up to 333 MHz processor speeds
• 66 MHz host bus speed
• L2 cache up to 512 KB for Pentium II processor and 128 KB for Celeron processor

The Pentium II processor is packaged in a Single Edge Contact (S.E.C.) cartridge. The cartridge includes the processor core, second-level cache, thermal plate, and back cover. The Celeron processor is packaged on a Single Edge Processor Package (SEPP). The SEPP has no cover and the heat sink attaches directly to the processor core.

The processor connects to the system board through the Slot 1 connector and a 330-pin edge connector. When mounted in the Slot 1 connector, the processor is secured by a retention mechanism attached to the motherboard.

Serial ports

The 9-pin D-Sub serial port connector on the back panel is compatible with 16450 and 16550A UARTs.

Super Input/Output (I/O) controller

This controller is ISA Plug and Play compatible, providing control for the integrated serial ports, parallel port, diskette drive, and keyboard or mouse. The controller provides:

• One 16450/16550A, software-compatible UARTs with internal send/receive 16-byte FIFO buffer
• Multimode bidirectional parallel port in standard, enhanced, and high-speed extended capabilities modes
• Industry standard diskette controller with 16-byte data FIFO, PC-AT and PS/2 drive mode support, and high-performance Digital Data Separator (DDS) for one diskette drive
• Keyboard controller
• Mouse controller

By default, the I/O controller interfaces are automatically configured during startup. The I/O controller can also be manually configured in the BIOS Setup utility.

Audio Subsystem

The following features are available on the audio subsystem:

• Analog audio
• PCI 64 voice wavetable synthesizer
• Mixer application
• 3-D positional audio
• Direct Sound 5.0
• Real-mode DOS compatibility

Video Subsystem

The following features are available on the video subsystem:

• ATI Rage Pro Turbo AGP 64-bit acceleration
• 4 MB high-speed SGRAM
• Integrated 32-bit AGP bus
• Up to 1600 × 1200 resolution, up to 85 Hz refresh, up to 64K colors (depending upon monitor)
• Standard VGA 640 × 480 analog monitor or better

Preventing Static Electricity

Static electricity precautions

Before opening the computer case, read and follow these precautions to prevent damage from static electricity.

Static electricity can permanently damage electronic components in the computer. Prevent electrostatic damage to the system by following static electricity precautions every time you open the computer case.

1. Turn off the computer power.
2. Touch a bare metal surface on the back of the computer.
3. Unplug all cords from the wall outlet.

Please also follow these static electricity precautions:

• Avoid static-causing surfaces such as plastic and styrofoam in your work area.
• Remove parts from their antistatic bags only when you are ready to use them. Do not lay parts on the outside of antistatic bags because only the inside provides antistatic protection.
• Always hold cards by their edges and their metal mounting bracket. Avoid touching components on the cards and the edge connectors that connect to expansion slots. Never slide cards or other parts over any surface.
