`About this Manual
`
`1
`
`This manual tells you how to set up and use the evaluation board and processor assembly included
`in your Intel® Pentium® III processor/840 Development Kit.
`
`1.1
`
`Content Overview
`
`Chapter 1, “About This Manual” - This chapter contains a description of conventions used in this
`manual. The last few sections tell you how to obtain literature and contact customer support.
`
`Chapter 2, “Getting Started” - This chapter provides complete instructions on how to configure the
`evaluation board and processor assembly by setting jumpers, connecting peripherals, providing
`power, and configuring the BIOS.
`
`Chapter 3, “Theory of Operation” - This chapter provides information on the system design.
`
`Chapter 4, “Hardware Reference” - This chapter provides a description of jumper settings and
`functions, and pinout information for each connector.
`
`Chapter 5, “BIOS Quick Reference” - This chapter describes how to configure the BIOS for your
`system. A summary of all BIOS menu options is provided.
`
`Appendix A, “Using Different Processors in the Board” - This appendix provides instructions for
`installing and using a Pentium III Processor with a 100 MHz processor side bus in your kit.
`
`Appendix B, “Termination Chip for Uniprocessor Systems” - This appendix provides contact
`information for obtaining a termination chip to insert in an unpopulated processor socket (for
`uniprocessor designs).
`
`Appendix C, “PLD Code Listing” - This appendix includes a sample code listing for the Post Code
`Debugger.
`
`Appendix D, “Bill of Materials” - This appendix contains the bill of materials for the evaluation
`board.
`
`Appendix E, “Schematics” - This appendix contains schematics for selected connectors and
`subsystems for the evaluation board.

`About this Manual
`
`1.2
`
`Text Conventions
`
`The following notations may be used throughout this manual.
`
`#
`
`Variables
`
`Instructions
`
`Numbers
`
`The pound symbol (#) appended to a signal name indicates that the signal
`is active low.
`
`Variables are shown in italics. Variables must be replaced with correct
`values.
`
`Instruction mnemonics are shown in uppercase. When you are
`programming, instructions are not case-sensitive. You may use either
`uppercase or lowercase.
`
`Hexadecimal numbers are represented by a string of hexadecimal digits
`followed by the character H. A zero prefix is added to numbers that begin
`with A through F. (For example, FF is shown as 0FFH.) Decimal and
`binary numbers are represented by their customary notations. (That is, 255
`is a decimal number and 1111 1111 is a binary number. In some cases, the
`letter B is added for clarity.)
`
`Units of Measure
`
`The following abbreviations are used to represent units of measure:
`
`amps, amperes
`gigabytes
`kilobytes
`kilo-ohms
`milliamps, milliamperes
`megabytes
`megahertz
`milliseconds
`milliwatts
`nanoseconds
`picofarads
`watts
`volts
`microamps, microamperes
`microfarads
`microseconds
`microwatts
`
`A
`Gbyte
`Kbyte
`KΩ
`mA
`Mbyte
`MHz
`ms
`mW
`ns
`pF
`W
`V
`µA
`µF
`µs
`µW
`Signal names are shown in uppercase. When several signals share a
`common name, an individual signal is represented by the signal name
`followed by a number, while the group is represented by the signal name
`followed by a variable (n). For example, the lower chip-select signals are
`named CS0#, CS1#, CS2#, and so on; they are collectively called CSn#. A
`pound symbol (#) appended to a signal name identifies an active-low
`signal. Port pins are represented by the port abbreviation, a period, and the
`pin number (e.g., P1.0).

`
`This chapter identifies the Intel® Pentium® III Processor/840 Development Kit’s key components,
`features and specifications, and tells you how to set up the board for operation.
`
`2.1
`
`Overview
`
`The evaluation board consists of a baseboard with two Intel Pentium III processors, the 840 chipset,
`and other system board components and peripheral connectors.
`
`Note: The evaluation board is shipped as an open system, allowing for maximum flexibility in changing
`hardware configuration and peripherals. Because the board is not in a protective chassis, the user
`must observe extra precautions when handling and operating the system.
`
`2.1.1
`
`Baseboard Features
`
`The evaluation board features are summarized below:
`(cid:127) Full support for two Intel® Pentium® III processors with 256 Kbytes of on-die L2 Cache at up
`to 866 MHz core bus speed. The baseboard supports a 100 or 133 MHz Processor System Bus.
`Intel® 840 chipset:
`— 82840 Memory Controller Hub (MCH)
`
`— 82801AA I/O Controller Hub (ICH)
`
`— 82802AB/82802AC Firmware Hub (FWH)
`
`— 82806AA PCI 64 Hub (P64H)
`
`300 or 400 MHz memory interface:
`
`— Four Rambus RDRAM* (RIMM) connectors
`
`— Two 64-Mbyte, PC-800 RDRAM RIMMs included
`
`— Support for up to 2 Gbytes of memory with 256-Mbit technology
`(cid:127) Accelerated Graphics Port (AGP) Support:
`— AGP Interface Specification Rev. 2.0 compliant
`
`— Backward compatible with the AGP 1.0
`
`— Single AGP 1X, 2X, 4X, 66 MHz, 3.3 V/1.5 V device support
`(cid:127) Two PCI 64 slots
`— 64-bit, 66 MHz
`(cid:127) Four PCI 32 slots
`— 32-bit, 33 MHz
`
`— PCI Specification Rev 2.1 compliant
