Introduction

Evaluation Board User’s Guide 5

1.0 Introduction

This document describes the Intel® 41210 Serial to Parallel PCI Bridge (also called 41210 Bridge)

Evaluation Board.

2.0 Overview

The Intel® 41210 Serial to Parallel PCI Bridge evaluation board is a PCI-Express enabling tool

with PCI-X expansion slots that are used to evaluate the operation of the 41210 Bridge. The 41210

Bridge evaluation board can be used to perform the following functions:

•Develop initialization code to configure the 41210 Bridge and associated logic and devices on

the local PCI-X bus as a intelligent controller.

•Evaluate the operation of the 41210 Bridge with a variety of PCI/PCI-X devices configured in

an intelligent subsystem.

•Build and evaluate a system.

•Testing of the 41210 Bridge feature set.

3.0 Features

The 41210 Bridge evaluation board has the following features:

•Complies fully with:

— Protocol and electrical standards of the PCI Local Bus Specification, Revision 2.3

—PCI-X Bridge Architecture, Rev 1.0 B

—PCI-Express Base Specification, Rev 1.0A

— PCI-Express Card Electrical Mechanical Specification

— PCI-Express Bridge Specification.

•Includes a 41210 "transparent" PCI-X Enhanced PCI-to-PCI Bridge that provides bridging

between two processor domains.

•Includes a host PCI-Express interface that plugs into any x8 PCI-Express option card slot.

•Provides dual peer PCI-X 133 MHz slots on separate bus segments in addition to each having

a segregated PCI-X100/66 MHz slot

•Three MICTOR LA connectors for logic analyzer interfacing of each bus segment

•Support, Products, and Documentation

Major Components

6Evaluation Board User’s Guide

4.0 Major Components

The major components for the 41210 Bridge include:

•For the A Secondary:

— J11 is the PCI-X 100/66 MHz card slot.

— J7 is the PCI-X 133 MHz card slot.

•For the B Secondary:

— J12 is the PCI-X 100/66 MHz card slot.

— J8 is the PCI-X 133 MHz card slot.

•MICTOR connectors U14-17 and U19-20 provide test points for the 64-bit S_AD signals.

•Header Connectors J3 and J4 provides test points for the PCI Bus A REQ/GNT signals.

•Header Connectors J5 and J6 provides test points for the PCI Bus B REQ/GNT signals.

•J1 is the JTAG connector.

•J15 provides access to the Microcontroller

•S1, S3, S4, are option switches.

Evaluation Board User’s Guide 7

5.0 DIP Switches

The 41210 Bridge uses a combination of switches and jumpers to control the various configuration

options. The following sections describe these controls.

Figure 2. Switches, Jumpers, and Connectors Location

5.0.1 Switch Settings

Table 1 and Table 2 describe the functions of the 41210 Bridge Evaluation Board switches. The

switches should be set before powering up the system. Figure 2 shows the Evaluation board

switches.

Note: When a switch is ON, it is Closed.

5.1 Jumpers

In addition to the DIP switches, the 41210 Bridge provides stake-pin jumpers for selecting special

features. The jumpers can be used for debugging and for evaluating special features. Table 3

through Table 8 show the configuration jumpers and the jumper function. Figure 2 shows the

41210 Evaluation Board jumpers.
