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 19

16 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.

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

164LX, see Appendix A.

Refer to Figure 2–1 for DIMM connector locations.

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 practices 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


5–3


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.

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 21164 Microprocessor

Install the new microprocessor in location U40 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.

5–4



6. Install the heat sink and heat-sink fan as directed in the following steps. A heat-

sink/fan kit is available from the vendor listed in Appendix A. Refer to

Figure 5–1 for heat-sink and fan assembly details.

Figure 5–1 shows the Fan/Heat-Sink Assembly on AlphaPC 164LX.

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.


5–5


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.

Important:

When installing the microprocessor, you must change the frequency of its clock output by setting the system clock divisor jumpers, as described

in Section 3.1.

boot

Syntax

Arguments

boot [-file <filename>] [-flags

<longword>[,<longword>]]

[-protocols <enet_protocol>] [-halt]

[<boot_device>]

<boot_device>

A device path or list of devices from which the firmware will attempt to boot. Use the

set bootdef_dev

command to set an environment variable that specifies a default boot device.

Options

Initializes the processor, loads a program image from the specified boot device, and transfers control to the loaded image.

boot Command Option

-file <filename>

-flags

<longword> [,<longword>]

-protocols

<enet_protocol>

-halt

Description

Specifies the name of a file to load into the system. Use the

set boot_file

command to set the environment variable that specifies a default boot file.

Specifies additional information for the operating system. For Tru64 UNIX systems, the following values may be used: i = Interactive boot s = Boot to single user a = Autoboot to multiuser

Use the

set boot_osflags

command to set an environment variable that specifies a default boot flag value.

Specifies the Ethernet protocols that will be used for a network boot. Values may be

mop

or

bootp

.

Forces the bootstrap operation to halt and invoke the console program after the image is loaded and the page tables and other data structures are set up.


7–5


Description

The

boot

command 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

-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 default boot 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

are 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.

7–6



Examples boot Command Example

>>>boot

>>>boot ewa0

>>>boot -file dec2.sys ewa0

>>>boot -protocol bootp ewa0

>>>boot -flags 0,1

>>>boot -halt dka0

Description

Boots the system from the default boot device.

Boots the system from Ethernet port ewa0.

Boots the file named dec2.sys from Ethernet port ewa0.

Boots the system using the TCP/IP BOOTP protocol from Ethernet port ewa0.

Boots the system from the default boot device using flag setting 0,1.

Loads the bootstrap image from disk dka0, halts the bootstrap operation, and invokes the console program. Subsequently, you can enter

continue

to transfer control to the operating system.

-ipr

-n <count>

-s <step>

Description

References internal processor register address space.

Specifies the number of consecutive locations to examine.

Specifies the address increment as a hexadecimal value.

This option allows you to override the increment that is normally derived from the data size.

Description

The

examine

command displays the contents of 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:0

and specify the size of the address space to be displayed. If a conflicting device, address, or data size is specified, the console ignores the command and issues an error response.

The display line consists of the device name, the hexadecimal address

(or offset within the device), and the examined data (also in hexadecimal).

The

examine

command supports the same options as the

deposit

command. Additionally, the

examine

command supports instruction decoding with the

-d

option, which disassembles instructions beginning at the current address.

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 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 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.
