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 19 and 19A are hexadecimal numbers.
16
Extents: Extents are specified by a single number or a pair of numbers in 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.
Italic Type: Italic type emphasizes important information and indicates complete
titles of documents.

Values indicated are for an AlphaPC 164SX motherboard with an Alpha 21164PC microprocessor
operating at 400 MHz, with 128MB SDRAM, excluding adapter cards and disk drives.
Caution: Fan sensor required. The 21164PC microprocessor cooling fan must
drive an RPM indicator signal. If the airflow stops, the sensor on the
motherboard detects that the RPM has stopped, and resets the system.
2.2 Environmental Requirements
The 21164PC microprocessor is cooled by a small fan blowing directly into the
chip’s heat sink. The AlphaPC 164SX 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.
The AlphaPC 164SX motherboard is specified to run within the environment listed
in Table 2–4.

AlphaPC 164SX Switch Configuration
The AlphaPC 164SX motherboard has a switchpack located at SW1, as shown
previously in Figure 2–1. These switches set the hardware configuration. Figure 3–1
shows these switch configurations.
3.1 Mini-Debugger (CF3)
The Alpha SROM Mini-Debugger is stored in the flash ROM and is enabled/
When this switch is off, it causes the SROM initialization to trap to the Mini-
Debugger after all initialization is complete, but before starting the execution of the
system flash ROM code.
3.2 CPU Speed Selection (CF[6:4])
The clock synthesizer at U45 makes it possible to change the frequency of the
microprocessor’s clock output. The switch configuration is set in SW1, CF[6:4].
microprocessor frequency divided by the ratio determines the system clock
frequency.
3.3 Fail-Safe Booter (CF7)
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 repro-
gramming the flash.
Refer to Section 8.4 for more information.

Memory and Microprocessor Configuration
For higher system speed or greater throughput, SDRAM memory can be upgraded
by replacing DIMMs with those of greater size.
When configuring or upgrading SDRAM, observe the following rules:
•
Each DIMM must be a 168-bit unbuffered version and have a frequency of
100 MHz.
•
•
Each bank consists of two DIMMs and must be fully populated.
Both DIMMs in the same bank must be of equal size.
5.1 Configuring SDRAM Memory
configurations available. As additional configurations become available, they will be
posted in online revisions of this manual on the Alpha OEM World Wide Web
Internet site. See Appendix A for the URL.
For a list of vendors who supply components and accessories for the
AlphaPC 164SX, see Appendix A.
Refer to Figure 2–1 for DIMM connector locations.
Note: 1Mb × 72 and 1Mb × 64 DIMMs are not supported.

•
Replace the Alpha 21164PC microprocessor with an Alpha chip that has a higher
speed rating.
•
Reconfigure the clock divisor switches.
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 prac-
tices is recommended.
An Alpha 21164PC 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, 52-mm fan, 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:
•

following steps:
1. Unplug the fan power/sensor cable from connector J14 (see Figure 2–1).
2. Remove the four 6–32 × 0.625-inch screws that secure the fan to the heat sink.
3. Remove the fan.
4. If the sink/chip/fan clip is used, remove it by unhooking its ends from around the
ZIF socket retainers.
5. Using a 3/8-inch socket, remove the two nuts securing the heat sink to the micro-
processor 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 21164PC Microprocessor
Install the new microprocessor in location U31 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.
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 15 in-lb, ±2 in-lb, (2.3 Nm, ±0.2 Nm).
The torque driver should have a mounted 3/8-inch socket.
5. Insert a nut into the 3/8-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 J14 (see
Figure 2–1). Fan airflow must be directed into the heat sink (fan label fac-
ing down toward the heat sink).
2. Using a calibrated torque driver set to 3 in-lb, ±1 in-lb, secure the fan to
the heat sink with four 6–32 × 0.625-inch screws.
3. Plug the fan power/sensor cable into connector J14.
Note:
When installing the microprocessor, you must change the frequency of
its clock output by setting the system clock divisor switches, as
described in Section 3.2.

Alpha SRM Console Firmware
7–5
Basic Alpha SRM Console Command Descriptions
Description
The bootcommand 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 -flagsoption can pass additional information to the operating
system about the boot that you are requesting. On an OpenVMS
system, the -flagsoption 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 -protocolsoption allows selection of either the DECnet
MOP or the TCP/IP BOOTP network protocols. The keywords mop
and bootpare 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.

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 repro-
gramming 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 164SX 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. Slide switch CF7 to off, as described in Section 3.3.
3. Power on your system.
4. Insert the AlphaPC 164SX SRM Console Firmware diskette into the diskette
drive.
5. Proceed to Section 7.4 and follow the procedures.
