Firmware Update Utility
Purpose
Write-Protecting
the Flash ROM
1–14
Digital Equipment Corporation distributes new Firmware
Update utility software whenever there are any changes to the
console firmware. The utility provides new firmware for the flash
ROM (read-only memory) in your system, including the console
program and diagnostic testing capabilities.
Refer to the release notes you receive with the software
update for an explanation of how to use the Firmware
Update Utility software.
For your convenience, your system is shipped from the factory
with the flash ROM write jumper, labeled W1 on the system
module, in the write-enabled position. Thus, there is no need
to remove the system unit cover and get inside the system unit.
You can update your console firmware with the latest version
using the release notes.
To write-protect the flash ROM so that it cannot be overwritten:
1. Open the system unit cover.
To avoid possible product damage, refer to Chapter 2 for
instructions on how to power off the system, open, and
work inside your system unit.
2. Locate the W1 jumper shown in Figure 1–2.
The default write-enabled position of the jumper is on pins 2
and 3.
