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 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.

Memory and Microprocessor Configuration  
For higher system speed or greater throughput, you can upgrade SDRAM memory  
by replacing DIMMs with those of greater size.  
When configuring or upgrading SDRAM, observe the following rules:  
Each DIMM must be a 168-pin unbuffered version and have a frequency of  
100 MHz.  
All DIMMs must be of equal size if they are in the same bank.  
5.1 Configuring SDRAM Memory  
Although not an exhaustive list, Table 5–1 lists the tested SDRAM memory  
configurations available.  
For a list of vendors who supply components and accessories for the AlphaPC  
Refer to Figure 2–1 for DIMM connector locations.  
Note:  
1Mb × 72 is not supported.

5.2 Upgrading SDRAM Memory  
You can upgrade memory in the AlphaPC 164LX by adding more DIMMs or  
replacing the ones that you have with a greater size. Refer to Figure 2–1 for DIMM  
connector locations.  
Use the following general guidelines:  
1. Observe antistatic precautions. Handle DIMMs only at the edges to prevent  
damage.  
2. Remove power from the system.  
3. Open levers and align the DIMM.  
4. Firmly push the module into the connector. Ensure that the DIMM snaps into the  
plastic locking levers on both ends.  
5. Restore power to the system.

Increasing Microprocessor Speed  
5.3 Increasing Microprocessor Speed  
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 prac-  
tices 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

Increasing Microprocessor Speed  
5.3.3 Removing the 21164 Microprocessor  
Remove the microprocessor currently in place at location U40 by performing the  
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.

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 anod-  
ized, hot-water-sealed, 6061-T6 aluminum. The nut material is 2011-T3 alu-  
minum (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

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  
flags 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.

Description  
The depositcommand 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:0and 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.

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 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 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.
