Updating PROM Code B-

This appendix describes how to update the different PROM codes and download I/O

firmware.

Updating PROM Code

All new or replacement boards come with the latest PROM code already installed.

However, occasionally circumstances might require that you update the PROM on

new hardware. In addition, Stratus releases revisions to PROM code periodically that

must be copied to (or burned on) your existing boards.

WARNING

Do not update PROM code yourself unless a Stratus representative

instructs you to do so. Improperly updating PROM code can damage a

board and interrupt system services. If you are not sure which PROM

code file you need to burn, contact the CAC. Also, do not attempt to

update CPU/memory PROM code if you are running with only one CPU

board.

The following sections describe how to update PROM code on CPU/memory boards,

console controllers, and SCSI adapter cards. Before you begin updating the PROM

code, you must determine which PROM file you need to burn. PROM code files are

located in the /etc/stratus/prom_code directory. Table B-1 describes the PROM

code file naming conventions.
