AlphaPC 164SX Switch Configuration

The AlphaPC 164SX motherboard has a switchpack located at SW1, as shown

previously in Figure 2–1. These switches set the hardware conf igu ra ti on. Fi gur e 3 –1 shows these switch configura ti ons .

3.1 Mini-Debugger (CF3)

The Alpha SROM Mini-Debugger is stored in the flash ROM and is enabled/ disabled by switch CF3. The default position for this switch is on (see Figure 3–1). When this switch is off, it causes the SROM initialization to trap to the MiniDebugger after all initialization is complete, but before starting the execution of the system flash ROM code.

3.2 CPU Speed Selection (CF[6:4])

The clock synthesizer at U45 makes it possible to change the frequency of the microprocessor’s clock output. The switch configuration is set in SW1, CF[6:4]. These three switches set the speed at power-up as listed in Figure 3–1. The microprocessor frequency divided by the ratio determines the system clock frequency.

3.3 Fail-Safe Booter (CF7)

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 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.

Refer to Sect ion 8.4 for more information.

Memory and Microprocessor Configuration

For higher system speed or greater throughput, SDRAM memory can be upgraded by replacing DIMMs with those of greater si ze.

When configuring or upgrading SDRAM, observe the following rules:

• Each DIMM must be a 168-bit unbuf fered version and have a frequency of

100 MHz.

• Each bank consists of two DIMMs and must be fully populated.

• Both DIMMs in the same bank must be of equal size.

5.1 Configuring SDRAM Memory

Although not an exhaustive list, Table 5–1 lists the tested SDRAM memory configurations avail able. As additional conf igurations become available, they will be posted in online revi sions of this manual on the Alpha OEM World Wide Web Internet site. See Appendix A for the URL.

For a list of vendors who supply components and accessories for the AlphaPC 164SX, see Appendix A.

Refer to Figure 2–1 for DIMM connector locations.

Note: 1Mb × 72 and 1Mb × 64 DIMMs are not supported.

5.2 Upgrading SDRAM Memory

You can upgrade memory in the AlphaPC 164SX by adding more DIMMs or

replacing the ones 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.

5–2 Memory and Microprocessor Configuration

Increasing Microprocessor Speed

3. Align the DIMM so that the notch in the DIMM matches the key in the socket.

4. Firmly push the DIMM st ra igh t into the connector. Ens ur e t hat t he DIMM snaps into the plastic locking levers on both ends.

5. Restore power to the system.

• Reconfigure the clock divisor switches.

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 21164PC mic roprocess or with a higher speed rating is ava ilable 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, 52-mm fan, 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

• 3/8-inch socket with 1/4-inch hex drive

• #2 Phillips-head screwdriver bit

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.

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, 60 61-T6 aluminum. The nut mat erial is 201 1-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 15 in-lb, ±2 in-lb, (2.3 Nm, ±0.2 Nm). The torque driver should have a mounted 3/8-inch socket.

5. Insert a nut into the 3/8-inch socket, place on on e of t he 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-s ink holes. Align the fan so that the fan power/sensor wires exit the fan closest to connector J14 (see Figure 2–1). Fan airflow must be directed into the heat sink (fan label facing down toward the heat sink).

2. Using a calibrated torque driver set to 3 in-lb, ±1 in-lb, secure the fan to the heat sink with four 6–32 × 0.625-inch screws.

3. Plug the fan power/sensor cable into connect or J14.

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

its clock output by setting the system clock divisor switches, as described in Section 3.2.

i = Interactive boot s = Boot to single user a = Autoboot to multiuser

Alpha SRM Console Firmware 7–5

Basic Alpha SRM Console Command Descriptions

Description

The boot command init ializes the processor, loa ds a program image from the specified boot device, and transfers control to tha t 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 p asses to the first successfully booted image. In a list, always enter network devices last because network bootstraps terminat e o nly if a fata l erro r 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 spec ify 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 valu e for the curr ent boo t req uest , but does not c hange the corresponding environment variable.

See the Environment Variables for Alpha SRM Console Commands section in this chapter for more information about environment variables.

8.4 Fail-Safe Booter

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 164SX 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 procedur e for updating your flash ROM.

(Sheet 3 of 3)

• You can also start the fail-safe booter manually as follows:

1. Power off your system.

2. Slide switch CF7 to off, as described in Section 3.3.

3. Power on your system.

4. Insert the Al phaPC 16 4SX SRM Con sol e Fi rmware diskette into the diske tt e

drive.

5. Proceed to Section 7.4 and follow the procedures.
