Features of the AlphaPC 164LX Motherboard 2–7

AlphaPC 164LX Jumper Configuration

The AlphaPC 164LX motherboar d has two groups of jumpers l ocated a t 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 s ystem cloc k output without ha ving to c hange the clock cryst al.
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 st ed in Fi gur e 3–1. The microprocessor frequency divi de d by
the ratio determines the system clock frequency.

3.2 Bcache Size Jumpers (CF1 and CF2)

The Bcache size jumpers ar e l ocated at J27–11/12 (CF) and J27–13/1 4 ( C F2). Thes e
jumpers configure the Bcache as specified in Figure 3–1.

Password Bypass Jumper (CF3)

3.3 Password Bypass Jumper (CF3)

AlphaBIOS provides password protection. However, Password Bypass is provided
for system setup or startup when the AlphaBIOS password is unavailable.

Password Bypass is enabled by inserting jumper CF3 in the J27 System
Configuration Jumper Block. This disables the AlphaBIOS password verification
and enable s the user to set up or start u p their system without the AlphaBIO S
password. Password Bypass also clears the password.

3.4 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 AlphaBIOS 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 8.5.

3.5 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

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 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 i n-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.

4. Plug the fan power/sensor cable into connect or J18.

Important: When installing the microprocessor, you must change the frequency of

its clock output by setting the system clock di visor jumpers, as desc ribed
in Section 3.1.

7.1.3 Upgrading AlphaBIOS

As new versions of Windows NT are released, it might be necessary to upgrade
AlphaBIOS to the latest version. Additionally, as improvements are made to
AlphaBIOS, it might be desirable to upgrade to take advantage of new features.

To upgrade from an earlier version of AlphaBIOS:

1. Insert the diskette or CD-ROM containing the AlphaBIOS upgrade.

2. Run the AlphaBIOS Setup program by restarting your system and pressing F2

when the boot screen is displayed.

3. In the main AlphaBIOS Setup screen, select Upgrade AlphaBIOS and press

Enter.
This menu option is used to upgrade to later versions of AlphaBIOS. When you

choose this option, the existing AlphaBIOS searches for an executable
AlphaBIOS update file; first on CD-ROM, then on diskette. Once the update file
has been found, AlphaBIOS executes it, and the firmware is upgraded.

4. After the upgrade is complete, the system either resets automatically or prompts
you to reset the system.

The fail-safe booter provides an emergency recovery mechanism when the primary
firmware image cont ai ned i n f la sh me mo ry has been corrupted. When fl ash 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
AlphaBIOS Firmware diskette. The fail-safe booter will load and run
AlphaBIOS from this diske tte. Proceed to Section 7.1. 3 and follow th e procedure
for updating your flash ROM.
