About This Manual
This manual describes the AlphaPC 164LX motherboard, a module for computing
systems based on the Alpha 21164 microprocessor and the companion 21174 core
logic chip. It describes the motherboard’s features and how to set its configuration
jumpers. This manual helps users to install and populate the AlphaPC 164LX
motherboard with memory modules and peripheral cards.
1.1 Manual Conventions and Terminology
The following conventions are used in this manual.
Caution: Cautions indicate potential damage to equipment, software, or data.
Note: Notes provide additional information about a topic.
Numbering: All numbers are decimal or hexadecimal unless otherwise indicated. In
case of ambiguity, a subscript indicates the radix of nondecimal numbers. For
example, 19 is a decimal number, but 1916 and 19A are hexadecimal numbers.
Extents: Extents are specified by a single number or a pair of numbers in square
brackets ([ ]) separated by a colon (:), and are inclusive. For example, bits [7:3]
specify an extent including bits 7, 6, 5, 4, and 3. Multiple bit fields are shown as
extents.
Register Figures: Register figures have bit and field position numbering starting at
the right (low-order) and increasing to the left (high-order).
Signal Names: All signal names are printed in boldface type. Signal names that
originate in an industry-standard specification, such as PCI or IDE, are printed in the
case as found in the specification (usually uppercase). Active low signals have either
a pound sign “#” appended, or a “not” overscore bar; for example, DEVSEL# and
RESET.

Values indicated are for an AlphaPC 164LX motherboard with an Alpha 21164 microprocessor
operating at 600 MHz, with 64MB SDRAM, excluding adapter cards and disk drives.
Caution:
Fan sensor required. The 21164 microprocessor cooling fan must have
a built-in sensor that will drive a signal if the airflow stops. The sensor is
connected to motherboard connector J18. When the signal is generated,
it resets the system.
2.2 Environmental Requirements
The 21164 microprocessor is cooled by a small fan blowing directly into the chip’s
heat sink. The AlphaPC 164LX motherboard is designed to run efficiently by using
only this fan. Additional fans may be necessary depending upon cabinetry and the
requirements of plug-in cards.

AlphaPC 164LX Jumper Configuration
The AlphaPC 164LX motherboard has two groups of jumpers located at J27 and J28,
as shown in Figure 2–1. These jumpers set the hardware configuration and boot
options. Figure 3–1 shows these jumper configurations.
3.1 CPU Speed Selection
The clock synthesizer at location U47 makes it possible to change the frequency of
the microprocessor’s system clock output without having to change the clock crystal.
Simply set the system clock divisor jumpers to adjust the frequency of the
microprocessor’s system clock output. These system clock divisor jumpers are
located at J27–1/2 (IRQ3), J27–3/4 (IRQ2), J27–5/6 (IRQ1), and J27–7/8 (IRQ0).
The jumper configuration is set in IRQ3 through IRQ0. These four jumpers set the
speed at power-up as listed in Figure 3–1. The microprocessor frequency divided by
the ratio determines the system clock frequency.
3.2 Bcache Size Jumpers (CF1 and CF2)
The Bcache size jumpers are located at J27–11/12 (CF) and J27–13/14 (CF2). These
jumpers configure the Bcache as specified in Figure 3–1.

3.3 Boot Option Jumper (CF7)
The boot option jumper is located at J27–23/24 (CF7). The default position for this
jumper is out (Figure 3–1). This jumper selects the image to be loaded into memory
from the system flash ROM. With the jumper out, the SRM Console firmware is
loaded. With the jumper in, the fail-safe booter is loaded. For more information
about the fail-safe booter, refer to Section 8.4.
3.4 Flash ROM Update Jumper (J28)
When J28–2/3 are jumpered together (default), the flash ROM is write-enabled.
When J28–1/2 are jumpered together, the flash ROM is write-protected.

This section describes how to complete the following actions to increase
microprocessor speed:
•
Replace the Alpha 21164 microprocessor with an Alpha chip that has a higher
speed rating.
•
Reconfigure the clock divisor jumpers.
5.3.1 Preparatory Information
Caution:
Static-Sensitive Component – Due to the sensitive nature of electronic
components to static electricity, anyone handling the microprocessor
must wear a properly grounded antistatic wriststrap. Use of antistatic
mats, ESD approved workstations, or exercising other good ESD practices is recommended.
An Alpha 21164 microprocessor with a higher speed rating is available from your
local distributor. See Appendix A for information about supporting products.
When replacing the microprocessor chip, also replace the thermal conducting
GRAFOIL pad. See Appendix A for information about the parts kit, which includes
the heat sink, GRAFOIL pad, two hex nuts, heat-sink clips, 60-mm fan, fan guard,
and four screws.
5.3.2 Required Tools
The following tools are required when replacing the microprocessor chip:
A TS30 manual nut/torque driver (or equivalent) with the following attachments is
required to affix the heat sink and fan to the microprocessor’s IPGA package:
•
1/4-inch hex bit
•
7/16-inch socket with 1/4-inch hex drive
•
#2 Phillips-head screwdriver bit

following steps:
1. Unplug the fan power/sensor cable from connector J18 (see Figure 2–1).
2. Remove the four 6-32 X 0.875-inch screws that secure the fan and fan guard to
the heat sink.
3. Remove the fan and fan guard.
4. If the sink/chip/fan clip is used, remove it by unhooking its ends from around the
ZIF socket retainers.
5. Using a 7/16-inch socket, remove the two nuts securing the heat sink to the
microprocessor studs.
6. Remove the heat sink by gently lifting it off the microprocessor.
7. Remove and discard the GRAFOIL heat conduction pad.
8. Thoroughly clean the bottom surface of the heat sink before affixing it to the
new microprocessor.
9. Lift the ZIF socket actuator handle to a full 90° angle.
10. Remove the microprocessor chip by lifting it straight out of the socket.
5.3.4 Installing the 21164 Microprocessor
Install the new microprocessor in location U40 by performing the following steps:
Note:
Install the heat sink only after the microprocessor has been assembled to
the ZIF socket.
1. Observe antistatic precautions.
2. Lift the ZIF socket actuator handle to a full 90° angle.
3. Ensure that all the pins on the microprocessor package are straight.
4. The ZIF socket and microprocessor are keyed to allow for proper installation.
Align the microprocessor, with its missing AD01 pin, with the corresponding
plugged AD01 position on the ZIF socket. Gently lower into position.
5. Close the ZIF socket actuator handle to its locked position.

a. Put the GRAFOIL thermal pad in place. The GRAFOIL pad is used to
improve the thermal conductivity between the chip package and the heat
sink by replacing micro air pockets with a less insulative material. Perform
the following steps to position the GRAFOIL pad:
1. Perform a visual inspection of the package slug to ensure that it is free of
contamination.
2. Wearing clean gloves, pick up the GRAFOIL pad. Do not perform this
with bare hands because skin oils can be transferred to the pad.
Memory and Microprocessor Configuration
5–5
Increasing Microprocessor Speed
3. Place the GRAFOIL pad on the gold-plated slug surface and align it with
the threaded studs.
b. Attach the microprocessor heat sink. The heat-sink material is clear anodized, hot-water-sealed, 6061-T6 aluminum. The nut material is 2011-T3 aluminum (this grade is critical). Perform the following steps to attach the heat
sink:
1. Observe antistatic precautions.
2. Align the heat-sink holes with the threaded studs on the ceramic package.
3. Handle the heat sink by the edges and lower it onto the chip package,
taking care not to damage the stud threads.
4. Set a calibrated torque driver to 20 in-lbs, ±2 in-lbs (2.3 Nm, ±0.2 Nm).
The torque driver should have a mounted 7/16-inch socket.
5. Insert a nut into the 7/16-inch socket, place on one of the studs, and
tighten to the specified torque. Repeat for the second nut.
6. If the sink/chip/fan clip is used, properly install it by positioning it over
the assembly and hooking its ends around the ZIF socket retainers.
c. Attach the heat-sink fan assembly:
1. Place the fan assembly on top of the heat sink, aligning the fan mounting
holes with the corresponding threaded heat-sink holes. Align the fan so
that the fan power/sensor wires exit the fan closest to connector J18 (see
Figure 2–1). Fan airflow must be directed into the heat sink (fan label
facing down toward the heat sink).
2. Place the fan guard on top of the fan. Orient the guard so that the corner
mounting areas lay flush against the heat sink.
3. Secure the fan and fan guard to the heat sink with four 6-32 X 0.875-inch
screws.
4. Plug the fan power/sensor cable into connector J18.
Important: When installing the microprocessor, you must change the frequency of
its clock output by setting the system clock divisor jumpers, as described
in Section 3.1.

Alpha SRM Console Firmware
7–5
Basic Alpha SRM Console Command Descriptions
Description
The boot command initializes the processor, loads a program image
from the specified boot device, and transfers control to that image. If
you do not specify a boot device in the command line, the default
boot device is used. The default boot device is determined by the
value of the bootdef_dev environment variable.
If you specify a list of devices, a bootstrap is attempted from each
device in the order in which the device is listed. Then control passes
to the first successfully booted image. In a list, always enter network
devices last because network bootstraps terminate only if a fatal error
occurs or if an image is successfully loaded.
The -flags option can pass additional information to the operating
system about the boot that you are requesting. On an OpenVMS
system, the -flags option specifies the system root number and
boot flags. If you do not specify a boot flag qualifier, the default boot
flag’s value specified by the boot_osflags environment variable is
used.
The -protocols option allows selection of either the DECnet
MOP or the TCP/IP BOOTP network protocols. The keywords mop
and bootp are valid arguments for this option. It is possible to set the
default protocol for a port by setting the environment variable
ewa0_protocols or era0_protocols to the appropriate protocol.
Explicitly stating the boot flags or the boot device overrides the
current default value for the current boot request, but does not change
the corresponding environment variable.
See the Environment Variables for Alpha SRM Console Commands
section in this chapter for more information about environment
variables.

Basic Alpha SRM Console Command Descriptions
Description
The deposit command writes data to the specified address, such as
a memory location, register, device, or file. The defaults for address
space, data size, and address are the last specified values. After
initialization, the default for address space is physical memory; for
data size, the default is a quadword; and for address, the default is
zero.
An address or device can be specified by concatenating the device
name with the address. For example, use pmem:0 and specify the
size of the address space to be written. If a conflicting device,
address, or data size is specified, the console ignores the command
and issues an error response.
Examples

Fail-Safe Booter
8.4 Fail-Safe Booter
The fail-safe booter provides an emergency recovery mechanism when the primary
firmware image contained in flash memory has been corrupted. When flash memory
has been corrupted, and no image can be loaded safely from the flash, you can run
the fail-safe booter and boot another image from a diskette that is capable of reprogramming the flash.
Starting the Fail-Safe Booter
You can start the fail-safe booter in one of two ways:
•
If the primary firmware image is unavailable when the system is powered on or
reset, the fail-safe booter runs automatically. When the fail-safe booter runs, the
system emits a series of beeps through the speaker as beep code 1-2-3; that is,
one beep and a pause, followed by two beeps and a pause, followed by three
beeps. After the diskette activity light flashes, insert the AlphaPC 164LX SRM
Console Firmware diskette. The fail-safe booter will load and run the
AlphaBIOS firmware update utility from this diskette. Proceed to Section 7.4
and follow the procedure for updating your flash ROM.
•
You can also start the fail-safe booter manually as follows:
1. Power off your system.
2. Add jumper CF7 as described in Section 3.3.
3. Power on your system.
4. Insert the AlphaPC 164LX SRM Console Firmware diskette into the diskette
drive.
5. Proceed to Section 7.4 and follow the procedures.
