HP E2466C Preprocessor
Interface for the Intel
Pentium® II Processor

The HP E2466C Preprocessor
Interface—At a Glance
The HP E2466C Preprocessor Interface, when used together with the
HP 16505A Prototype Analyzer, provides a complete interface for state or
timing analysis between any Intel Pentium® II processor target system and
the HP logic analyzers listed below. The HP E2466C Preprocessor Interface
requires that the logic analyzer module is in an HP 16500B/C mainframe; the
HP 16505A Prototype Analyzer is also required.
The inverse assembler provides Pentium II processor assembly language
mnemonics and accurate instruction execution tracking of up to four
processors. The inverse assembler also supports Intel’s MMXTechnology.
The HP E2467A APIC Bus Preprocessor Interface can also be used with the
HP E2466C Preprocessor Interface to provide simultaneous bus analysis.
For instruction disassembly, Branch Trace Messagesmustbe enabledand
cachesmust bedisabled. Thisrequiresa Pentium IIprocessor run-control tool
(suchas theHP E3493A) anda 30-pin debug porton the target system.

Setting Up the Preprocessor Interface
This chapter explains how to set up the HP E2466C Preprocessor
Interface hardware and software, configure the preprocessor, and
connect the preprocessor to supported logic analyzers. It also
contains information on setting up the HP 16505A Prototype Analyzer
for use with the HP E2466C Preprocessor Interface and using the
HP E2467A APIC Bus Preprocessor Interface.
1-2 Preprocessor Interface for the Pentium II Processor

Before You Begin
This section lists the logic analyzers supported by the HP E2466C, and
provides other information about the analyzers and the preprocessor.
Equipment Supplied
•The preprocessor interface circuit board.
•Cable, interposer, bottom clamp, and heat sink.
•The configuration files, for the logic analyzer and HP 16500B/C mainframe,
on a 3.5-inch disk. There are also Demo files for all supported logic
analyzers on the disk.
•Transaction tracker/inverse assembly software for the HP 16505A
Prototype Analyzer on a 3.5-inch disk.
•This User’s Guide.
Minimum Equipment Required
•The HP E2466C Preprocessor Interface, configuration files, and
transaction tracker software.
•An HP 16505A Prototype Analyzer.
•A target system with the microprocessor circuit board removed from the
S.E.C. cartridge. Detailed instructions for disassembling the S.E.C.
cartridge can be found in Intel’s S.E.C. Cartridge Disassembly
Application Note.
•One of the logic analyzers listed in the table on page ii, in an HP 16500B/C
Logic Analysis Mainframe.
For instruction disassembly, Branch Trace Messages must be enabled and
instruction cachesmust be disabled. Thisrequires a Pentium II processor
run-control tool such asthe HP E3493A, and a 30-pin debug port on the target
system. The HP E3493A run-control tool requires firmware version v2.15or
higher for the Pentium II processor.
Preprocessor Interface for the Pentium II Processor 1-3

Additional Capabilities/Equipment Required
For APIC Bus analysis, the HP E2467A APIC Bus Preprocessor Interface can
be used with the HP E2466C.
Additional configuration software for increased analysis of Pentium II
processor target systems is available with the appropriate Intel
non-disclosure forms. Contact your HP Sales Office for further information
about the restricted version.
Before You Begin
1-4 Preprocessor Interface for the Pentium II Processor

Setting Up the Preprocessor Interface
Hardware
Setting up for the preprocessor interface hardware consists of the following
major steps:
1Turn off the logic analyzer and the target system.
CAUTION To protect your equipment, remove the power from both the logic analyzer
and the target system before you make or break connections. Because the
logic analyzer supplies power to the preprocessor interface, the logic
analyzer should always be powered up before the target system; when
powering down, power down the target system first and then power down
the logic analyzer.
2Set the State/Timing Mode (Mode) switch and the
Compacted/Expanded Clock Qualifier switch according to the type of
analysis you wish to perform.
3Disassemble the S.E.C. cartridge containing the microprocessor.
4Install the preprocessor interface in the target system.
5Connect the logic analyzer pods to the cable connectors of the
preprocessor interface board.
To select the operating mode
Two switches on the preprocessor select the operating mode. The LEDs
indicate the selected mode (see table 1). The HP 16505A Prototype Analyzer
must also be updated to match the Mode (state or timing) selected by the
switches.
The MODE switch selects either State or Timing mode. In State mode, the
QUAL switch selects the clock qualifier to be either Compacted or Expanded.
The QUAL switch has no effect in timing mode.
The Expanded clock qualifier acquires a state for every bus clock when there
are transactions outstanding on the bus; no states are acquired when there
are zero outstanding transactions.
The Compacted clock qualifier maximizes the number of transactions
captured and is generally preferred.

Refer to Chapter 3, section "Modes of Operation", for more details on the
preprocessor operating modes and clock qualifiers.

To disassemble the S.E.C. cartridge
The S.E.C. cartridge consists of a thermal plate, skirt, cover, and
microprocessor card. The thermal plate, skirt, and cover must be removed to
access the processor card.
Detailed instructions for disassembling the S.E.C. cartridge can be obtained
from Intel. The following procedures are only intended as an overview.
Disassembling the S.E.C. cartridge voids the Intel warranty. Also, there is ahigh
probability that the cover and thermal plate will be damaged during
disassembly, and a small possibilitythat themicroprocessorcard will be
damaged. The S.E.C. cartridge isnot intended to be reassembledafter
disassembly.
1Remove the S.E.C. cartridge from the target system by pushing in the
two tabs on top of the cartridge, then pulling the cartridge up.

2Using the instructions in the Intel S.E.C. Cartridge Disassembly
Application Note, insert a 1/8" small flat blade screwdriver between
the cover and the thermal plate, next to one of the four barbed posts
located at each corner of the thermal plate. Twist the screwdriver
until the barbed post pops free. Repeat this procedure for the other
barbed post at the same end of the cartridge, then repeat for the
other end of the cartridge.
Disassembling the S.E.C. Cartridge
3Using the instructions in the Intel S.E.C. Cartridge Disassembly
Application Note, use fine-tip round nose pliers to separate the tabs
on the thermal plate away from the locator pins. Remove the spring
retainer clips, then separate the thermal plate from the
microprocessor circuit board.

To connect to the target system
The probe end of the preprocessor connects directly to the microprocessor
on the target system.
1To prevent equipment damage, remove power from both the logic
analyzer and the target system.
CAUTION Serious damage to the target system or preprocessor interface can result
from incorrect connection. Note the position of pin A1 on the preprocessor
interposer and on the microprocessor before making any connection. Take
care to align the preprocessor connector assembly with the pins on the
microprocessor so that all pins make contact.
2Install the interposer onto the microprocessor on the target system.
The alignment tabs on the interposer aid in making proper alignment.
Ensure that pin A1 is oriented correctly (see figure below).

4Loosen the screw on the underside of the bottom clamp.
5Work the four clamp posts of the bottom clamp through holes in the
target system PC board. Slide the clamp on the probe end of the PC
board back, then work the four clamp posts on through the
preprocessor PC board.
Securing the Preprocessor Connection
6Move the top sliding clamp forward on the probe end until it holds
the clamp posts of the bottom clamp.
7Tighten the screw on the underside of the bottom clamp until it is
snug (80 inch-ounces of torque). If the screw is too loose, the
preprocessor will not make good contact with the microprocessor
pins. If the screw is too tight, it may damage the interface connector.
8Insert the heat sink into the rectangular opening on top of the
preprocessor interface. Select an orientation that does not interfere
with the target system. Tighten the two screws until the heat sink is
snug. Do not overtighten.
9Connect the heat sink to a +12 Volt power source. The black wire is
ground, and the yellow wire is positive. To protect your target
system and the preprocessor interface, ensure the fan is running
whenever the target system is powered.
