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.

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 enables the user to set up or start up their system without the AlphaBIOS
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.

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 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.

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.

not format the large partition with NTFS. You will have the opportunity to do this
during the Windows NT installation.
7–4
Note:
AlphaBIOS assigns “disk 0” to the hard disk with the lowest SCSI ID
number on the first bus in your system. If no SCSI devices are present,
AlphaBIOS assigns disk 0 to the first IDE hard drive.
Caution:
If you have any information on your disk that you want to save, be sure
to back it up before using express hard-disk setup.

7.2 Installing the Windows NT Operating System
This section supplements the Microsoft Windows NT installation guide for installing
the Windows NT operating system on an AlphaPC 164LX system.
If you already have a previous version of Windows NT installed, see the Microsoft
Windows NT installation guide for information about how to upgrade to a new version of the operating system.

Installing the Windows NT Operating System
7.2.1 Requirements
You need the following hardware and software to install the Windows NT operating
system on an AlphaPC 164LX system:
•
A 100MB or larger drive
Note:
For information regarding supported IDE/ATA hard drives, ATAPI
CD-ROM drives, SCSI hard drives, CD-ROM drives, and controllers
supported as boot/installation devices, see the README.TXT file on
the AlphaPC 164LX AlphaBIOS Firmware diskette.
•
32MB or more of memory
•
The Microsoft Windows NT compact disk
•
The AlphaPC 164LX AlphaBIOS Firmware diskette
•
The AlphaPC 164LX Windows NT 4.0 Installation diskette
Note:
The AlphaPC 164LX Windows NT 4.0 Installation diskette is required
for the Windows NT 4.0 operating system. Future versions of Windows
NT may not require this diskette. Contact your OEM or system vendor
for details.
7.2.2 Before Installing Windows NT
Before installing Windows NT, ensure that you have completed the following tasks:
•
Use the CMOS Setup program to:
–
Set the system date and time
–
Verify that all other standard CMOS settings match your system.
Refer to Section 7.1.4 for more information about the CMOS Setup program.
•
Perform an express hard-disk setup. This configures the first hard disk that
AlphaBIOS detects in your system with the recommended default partition
arrangement. See Section 7.1.5 for more information on setting up your hard
disk. If you do not want to use the express hard-disk setup, refer to the online
AlphaBIOS documentation for other hard-disk setup options.

Installing the Windows NT Operating System
7.2.3 Starting Windows NT Setup
Windows NT Setup, located on the Microsoft Windows NT compact disk, installs
the Windows NT operating system. Windows NT Setup provides a brief description
of the available key functions at the bottom of the screen.
During the Windows NT installation procedure, you may be prompted for the type of
computer that you have. For the AlphaPC 164LX system, choose DIGITAL
AlphaPC 164LX. If AlphaPC 164LX is not one of the choices, choose “other” after
you have inserted the AlphaPC 164LX Windows NT 4.0 Installation diskette. The
following procedure supersedes the Starting Setup on a RISC-based Computer section of the Microsoft Windows NT installation guide.
To start the Windows NT Setup program:
1. Insert the Windows NT compact disc in the CD-ROM drive.
2. Restart your computer.
3. Start AlphaBIOS Setup, select Install Windows NT, and press Enter.
4. Follow the instructions on the screen.

Troubleshooting
This chapter contains information about troubleshooting hardware and software
during AlphaPC 164LX startup.
8.1 Password Bypass
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 (see Figure 3–1). This disables the AlphaBIOS
password verification and enables the user to set up or start up their system without
the AlphaBIOS password. Password Bypass also clears the password.
8.2 Hardware Startup
Use the following troubleshooting steps if video is not working on your system. If
you still have no video after reviewing these steps, please call your system vendor.
Troubleshooting Steps: No Video
1. Check the connection to the ac outlet.
2. Check the voltage setting on the power supply (115 V ac in the U.S.).
3. Check that the frequency/jumper selection matches the speed of the Alpha chip.
4. Check that the oscillator is installed into the motherboard correctly.
5. Check that the CPU fan is connected and spinning.
6. Ensure that the flash ROM update procedure was performed correctly. If you
have a terminal attached to COM1, check the output for error messages after
verifying that the flash ROM update procedure was performed correctly.
7. Reseat the video card and ensure that it is connected to the monitor.

8.5 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
AlphaBIOS Firmware diskette. The fail-safe booter will load and run
AlphaBIOS from this diskette. Proceed to Section 7.1.3 and follow the procedure
for updating your flash ROM.
Troubleshooting

You can also start the fail-safe booter manually as follows:
1. Power off your system.
2. Add jumper CF7 as described in Section 3.4.
3. Power on your system.
4. Insert the AlphaPC 164LX AlphaBIOS Firmware diskette into the diskette
drive.
5. Proceed to Section 7.1.3 and follow the procedures.
