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 sy stem cloc k output wi thout ha ving to c hange the clock cr ystal.
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 li ste d in Fig ure 3–1. The microprocessor frequency divi ded by
the ratio determines the system clock frequency.
3.2 Bcache Size Jumpers (CF1 and CF2)
The Bcache size jumpers ar e located at J27–11/12 (CF) and J27–13/1 4 (CF2). These
jumpers configure the Bcache as specified in Figure 3–1.
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 informatio n
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.

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 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
screws.

Description
The boot command initiali zes the processor , l oa ds a pr ogr am i ma ge
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 th e order in wh ich the device is listed. Then control passes
to the first successfully booted image. In a list, always enter network
devices last because network bootst raps t ermi nate on ly if a fa tal er ror
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 def aul t bo ot
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 ar e valid ar guments for th is 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 curr ent boo t requ est, bu t d oes not chang e

a memory location, register, device, or file. The defaults for address
space, data size, and address are the last specified values. After
initialization, the defau lt 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.
The optional device name (or address space) selects the device to
access.
<address>
The address specifies the first location to examine within the current
device. The address can be any legal address specified.

Fail-Safe Booter
8.4 Fail-Safe Booter
The fail-safe booter provides an emergency recovery mechanism when the primary
firmware image cont ained in flash memory has been corrupted. Wh en 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, inser t 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 diskett e into t he disk ett e
drive.
5. Proceed to Section 7.4 and follow the procedures.
