6 Features of the AlphaPC 164 Motherboard

2.1 Power Requirements

The AlphaPC 164 motherboard has a total power dissipation of 116 W, excluding
any plug-in PCI and ISA devices. Table 3 lists the power req uirement for each dc
supply voltage.

The power supply must supply a DCOK signal to the system reset logic.

Caution: Fan sensor required. The 21164 microprocessor coolin g fan must

have a built-in sensor that will drive a signal if the airflow stops. The
sensor is connected to motherboa r d connector J21. 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 Alph aPC 164 mother board is de sign ed to run eff iciently by usin g only
this fan. Additional fans may be necessary depending upon cabinetry and the
requirements of plug- in cards.

The AlphaPC 164 motherboard is specif ied to run within the environment listed in
Table 4.

8 AlphaPC 164 Jumper Configuration

3 AlphaPC 164 Jumper Configuration

The AlphaPC 164 motherboard has three groups of jumpers at location J1, J30, and
J31. These jumpers set the hardware configuration and boot options. Figure 1 shows
the jumper location on the AlphaPC 164 motherboard. Figure 2 shows the jumper
functions for each group . Sec tion 3.1 through Section 3.7 describe the jumper con­figurations.

3.1 Memory Bus Width Jumper (J1)

The memory bus width can be either 128 bits (J5 through J8 populated with SIMMs
and J9 through J12 empty) or 256 bits (J5 through J12 popul at ed with SIMMs).
When using a memory bus width of 128 bits, jumper J1 must be in. When using a
memory bus width of 256 bits, jumper J1 must be out.

3.2 System Clock Divisor Jumpers (IRQ3 Through IRQ0)

The system clock divisor jumpers a re loc ated at J30–1/2 (IRQ3), J30–3/4 (IRQ2),
J30–5/6 (IRQ1), and J30–7/8 (IRQ0) . The jumper configura tion set in IRQ3 t hrough
IRQ0 determines the freque ncy of the micropr ocessor’s system clock output. These
four jumpers set the speed at power-up a s liste d in Figure 2. The microprocessor fre­quency divided by the ratio dete rmine s the system clock frequency.

3.3 Bcache Size Jumpers (CF1 and CF2)

The Bcache size jumpers are located at J30–11/12, CF1 and J30–13/14, CF2. These
jumpers configure the Bcache as specified in Figure 2.

3.4 B ca ch e Speed Jumpe rs (CF 4 an d CF5 )

The Bcache speed jumpers are located at J30–17/18, CF4 and J30–19/20, CF5.
These jumpers select the Bcache timing parameters used to compute a value that is
loaded into the microproc ess or’s Bcache configuration register at power-up tim e.
Because the Bcache SRAMs are soldered onto the board, the default jumper configu­ration selecting a n SRAM access time of 9 ns as shown in Figure 2 will always be
used.

3.5 Mini-Debugger Jumper ( CF6)

The Mini-Debugger jumper is located at J30–21/22 (CF6). The default position for
this jumper is out (Figure 2). The Alpha SROM Mini-Debugge r is stored in the
SROM. When this jumper is in, it causes the SROM initialization to trap to the Mini­Debugger (communic ation t hrough c onnector J32) after all initi alizat ion i s complet e,
but before starting the execution of the system flash ROM code.

3.6 Boot Option Jumper (CF7)

The boot option jumper is located at J30–23/24 (CF7). The default position for this
jumper is out (Figure 2). This jumper sele cts the image to be loaded into memory
from the system flash ROM. With the jumpe r out, the Alpha 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 7.4.3.

3.7 Flash ROM Update Jumper (J31)

When J31–2/3 are jumpered togethe r (defa ult), the flash ROM is write-enabled.
When J31–1/2 are jumpered togethe r, the flash ROM is write-protected.

Configuring and Upgrading DRAM Memory 19

5 Configuring and Upgrading DRAM

Memory

For higher system speed or greater throughput, DRAM memory can be upgraded
either by replacing SIMMs with those of greater size, or by widening the memory
bus from 128 bits to 256 bits by adding more SIMMs.

Note: When configuring or upgrading DRAM, the following rules must be

observed:

• All SIMMs must be 36-bit and have a 70-ns or faster access time.

• All SIMMs must be of equal size.

5.1 Configuring DRAM Memory

Table 22 lists the DRAM memory configurations a va ilable. Refer to Figure 1 for
SIMM connector location.

20 Configuring and Upgrading DRAM Memory

5.2 Upgrading DRAM Memory

There are three options for upgrading DRAM memory (Table 23).

To widen the memory bus to its 256-bit maximum (upgrade option 2), add four
SIMMs and make a jumper change (remove J1). The SIMMs that you add must be of
the same size (nMb

X 36-bit) and have an access time equal to or less than the four

SIMMs already in the system. Refer to Figure 1 for SIMM connector and jumper
location.

1. Observe antistatic precautions. Handle SIMMs only at the edges to prevent
damage.

2. Remove power from the system.

3. Hold the SIMM at an angle with the notch facing the key in the socket.

4. Firmly push the module into the connector and stand the module upright. Ensure
that the SIMM snaps into the metal locking clips on both ends.

5. For 128-bit memory bus width, jumper J1 must be in. For 256-bit memory bus
width, jumper J1 must be out.

6. Restore power to the system.

Table 23 Memory Upgrade Options

Option

Width Be f ore

Memory Bus

1 128-bit 128-bit Replace the 4 SIMMs in socket s J5 thr ough J8

with SIMMs of greater size, thus retaining the
128-bit memory bus widt h.

2 128-bit 256-bit Add 4 SIMMs in sockets J9 through J12 with

sizes equal to those in sockets J5 through J8,
thus widening the memory bus width to 256
bits.

3 256-bit 256-bit Replace the 8 SIMMs in sockets J5 through

J12 with SIMMs of greater size.

Table 25 lists the AlphaPC 164 ISA I/O space address mapping.

6.3 Flash ROM Address Map

The address range for the flash ROM is FFF8.0000–FFFF .FFFF. Flash space of
1MB is obtained by double mapping this 512KB space. FLASH_ADR19 register at
I/O location 800h provides this function. Writing a 0 to this location enables the
lower 512KB of flash. Writing a 1 to this location e nables the upper 512KB of flash.

7.4.1 Starting the Firmware Update Utility

To start the firmware update utility from the Alpha SRM Console firmware update
diskette, follow this procedure:

1. Insert the Alpha SRM Console firmware update diskette into the diskette drive.

2. At the Alpha SRM Console prompt, enter the following command:

>>>fwupdate

Note: Be cau se the fi rm w are up da te utility reinitializes some system compo-

nents, it may appear as if your system is restarting.

3. Proceed to the Section 7.4.2 .

7.4.2 Running the Firmware Update Utility

7.4.3 Troubleshooting the Firmware Update Utility Procedure

The fail-safe boote r provide s an emergency recovery mechanism when the primary
firmware image contained in flash memory has been corrupted. When flash memory
has been corrupted, such that no image safely loads from the flash, the fail-safe
booter can be run to facilita te booting another image from a diskette that is capable
of reprogramming the flash.

7.4.3.1 Running the Fail-Safe Booter

The fail-safe boote r can be starte d in one of two ways:

• If the primary firmware image is unavailable when the system is powered on or

reset, the fail-safe booter automatically runs.

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. Then the disk et te activity light flashes.

1. To start the firmware update utility, you must insert the Alpha SRM
Console firmware update diskette into the diskette drive.The diskette
contains the file FWUPDATE. EXE and the Alpha SRM Console ROM
image.

Default Console Device Commands

Terminal attached to the COM1
serial port

>>>set console serial
>>>init

Graphics display unit

>>>set console graphics
>>>init

1. Add jumper CF7 as described in Section 3.6.

2. Insert the Alpha SRM Console firmware update diskette into the diskette
drive.

3. Re turn to Section 7.4.2 .
