1.0 Introduction This document introduces the BX400ii Interposer Board and provides installation instructions. The BX400ii Interposer Board with the Intel® Mobile Pentium® II Processor emulates the functionality of the Intel® Pentium® II Processor Mobile Module to provide a bus interconnect for emulation and logic analysis tools. This board is used for Intel Pentium II Processor Mobile Module system designs. Note: 1.
Introduction 1.3 Pentium® II Processor Mobile Module: Mobile Module Connector 2 or Low Power Pentium II Processor Module The Pentium II Processor Mobile Module: Mobile Module Connector 2 (400-pin MMC-2) or Low Power Pentium II Processor Module (LPM) is a small, highly integrated assembly containing an Intel Pentium II processor and its immediate system-level support.

Getting Started 2.0 Getting Started The BX400ii Interposer Board requires a Mobile Pentium II Processor in mini-cartridge at a frequency corresponding to the mobile module that is being emulated. 2.1 Unpacking Instructions Carefully unpack the contents of the box and verify that all of the items in the packing list are present. If items are missing or damaged, contact Intel or your authorized distributor. 2.1.
Getting Started Note: 2.2.2 Please consider the thermal requirements of your Mobile Pentium II processor and ensure that the proper thermal management solution is in place. Emulator/Logic Analyzer Connect the 30-pin cable from the emulator or logic analyzer to the debug port connector on the BX400ii Interposer Board. If you have a debug port designed into your system, only the debug port on the BX400ii Interposer Board will function.
Hardware Reference 3.0 Hardware Reference For a hardware layout of the BX400ii Interposer Board, refer to Figure 5 on page 13. For board dimensions and keepout space requirements, refer to Figure 2 and Figure 3 on page 8. 3.1 Connector Definitions Changes to the hardware are not required for the BX400ii Interposer Board.
