Installing Cache Memory

Preparing for the Installation
Prerequisite Hardware
Confirm that you have the correct hardware before you begin. At a minimum, your
Personal Workstation 433 a-Series system should be running Windows NT 4.0 and have:
•

32-MB memory.

•

Floppy diskette drive.

•

200-MB or greater SCSI hard disk.
CAUTION: Do not touch any electronic component unless you are safely
grounded. Wear a grounded wrist strap or touch an exposed metal part of the
system unit chassis. A static discharge from your fingers can result in
permanent damage to electronic components.

Cache Memory Kit Contents
Ensure that you have the following items, shown in Figure 1:

c 433a Cache memory module (2-MB)
d Floppy diskettes (one shown; your kit has two, AK-R4R5A-CA, which contains the
APU firmware update, and AK-R4Z2A-CA, which contains the HAL update)

Installing Cache Memory

Shutting Down the Microsoft Windows NT Operating System
Before proceeding with the update, perform the following steps to shut down the Microsoft
Windows NT operating system:
1.

Close any application data files you have open as well as any applications you have running.
Most application programs prompt you to save the information before closing.

Shut down the operating system as Table 1 outlines.

Table 1: Operating System Shut Down
Step

Action

Click the Start button.

Click Shut Down...

Select Shut down the Computer?

Click the Yes button.

Wait for the operating system to complete the shutdown process. The Microsoft Windows NT
operating system displays a window indicating it is safe to turn off or restart the system.

Loading the HAL
Before installing the cache memory, ensure that the HAL (hardware abstraction layer) is
properly loaded onto your system. This update procedure is applicable for customers
whose systems have Windows NT preinstalled. In addition, customers whose systems do
not have Windows NT preinstalled (that is, systems for which the Windows NT end user
agreement [EULA] has not been completed) also should follow this procedure.
Use the following procedure to load the HAL:
1.

Insert the floppy diskette labeled “DIGITAL Personal Workstation ‘a’-Series Cache Module
Support Diskette, Disk 2 of 2, HAL Update” into the floppy diskette drive.

Power on the system.

From the AlphaBIOS main menu, select Utilities Run → Maintenance Program.
Press [Enter].

In the Run Maintenance Program dialog box, fill in the fields as follows:
Program Name: halcopy
Location:
A:

Press [Enter].

NOTE: If you see a File Open Error warning box, make sure that you typed “halcopy”
correctly and that you have inserted the correct diskette. Then retry.

Installing Cache Memory

The following messages display:
Halcopy utility starting...
Do you wish to complete the HAL upgrade?
Y to complete upgrade, anything else to quit…>

Press Y to complete the upgrade.

The following messages display:
Reading new HAL…
Updating HAL…
Update completed.
Hit any key to return to AlphaBIOS.

NOTE: If you see any messages that include the <Error> string, contact your Digital Field
Service or VAR support staff for assistance.
9.

Press any key.

10. Your HAL update is now complete. When you restart Windows NT on your DIGITAL
Personal Workstation, you will be using the updated HAL.

Copying the HAL over the Internet
If you prefer to copy the HAL over the Internet, follow the next steps:
1.

Open the URL http://www.windows.digital.com/support/sysoft.htp.

You will be at the Windows Enterprise Computing screen.

Scroll down to the DIGITAL Personal Workstation heading and choose 433a.

You will now be at the DIGITAL Personal Workstation 433a Support Files screen.

Choose HAL for WNT 4.0.

Save the files on your system.

Unzip the archive and copy the files (HAL filename is halmiata.dll) to a floppy diskette.
Label it “DIGITAL Personal Workstation “a”-Series, Cache Module Support Diskette, Disk 2
of 2, HAL Update.”

10. The display now reads:
Boot dva0.0.0.0.1 -flags 0
block 0 of dva0.0.0.0.1 is a valid boot block

After the system is finished reading the floppy diskette, the SRM >>> prompt changes to
the APU → prompt. At this point, you can proceed to perform the update outlined next.

At the APU → prompt, type update. Press [Return].

The following displays:
APU-I ARE YOU READY TO PROGRAM (SRM) ROM DEVICE? (Y/N)

Type y. Press [Return].

Installing Cache Memory

Installing the Cache Memory Module
Prior to performing the next steps, ensure that:
1.

The HAL has been copied to the appropriate location in the system partition on your system
disk.

AlphaBIOS and POST have been updated.

Microsoft Windows NT operating system has been shut down. (See earlier instructions.)

The system has been powered off.

Powering Off the System
CAUTION: Do not turn off power to your system or peripherals until the shutdown
sequence has completed.
Once you have safely shut down the Microsoft Windows NT operating system as described
earlier, turn off the system power before proceeding.

Removing the System Cover
CAUTION: To avoid system damage from static discharge, wear a grounded wrist strap
before you touch anything inside the system.
To remove the system cover, refer to Figure 2 and perform the following steps:
1.

Shut down your system and all peripheral devices.

Unplug the power cord and all other cables.

WARNING: Allow at least 45 seconds for the power supply capacitors to discharge
safely.
3.

Remove the system lock, if necessary.

Locate and loosen the three thumb screws that fasten the system cover to the rear panel.
Place your thumbs on the upper corners of the system cover, pull back on the cover, and
slide the cover back and away from the system enclosure. Then lift the cover up and away
from the system.

Removing the MLB
NOTES: 1. Before beginning this section, confirm that you have removed all cables; this
will facilitate the next steps. 2. Remove the MLB from the system to facilitate access to the
cache memory connectors on the MLB.
CAUTION: To avoid system damage from static discharge, wear a grounded wrist strap
before you touch anything inside the system.
Refer to Figure 3 and follow these steps to remove the MLB from your system:
1.

With the system cover off, release the two MLB-retaining clips on top of the MLB.

Hold onto either end of the MLB as you slide it up and out of the system chassis.

Carefully place the MLB onto a static-free, flat surface.

Using the alignment pins on the MLB as a guide, carefully position the cache memory onto the
MLB connectors.

Once the module is properly aligned, firmly press down on it to engage the connectors.

Installing Cache Memory

NOTE: Some systems shipped without the alignment pins in place. If you received a
system without pins, use the corresponding holes in the cache memory and the MLB as a
positioning guide.
CAUTION: Do not touch any electronic component unless you are safely grounded.
Wear a grounded wrist strap or touch an exposed metal part of the system unit chassis. A
static discharge from your fingers can result in permanent damage to electronic
components.

Replacing the MLB
Refer to Figure 5 and follow these steps to replace the MLB into the system after you have
installed the cache memory:
1.

Hold onto either end of the MLB as you slide it down into the system chassis.
