To update a diagnostics PROM, enter:
prom -w <volume_no.> <Diag_PROM_source_file> <slot_ID >
For example, to upgrade the diagnostics PROMs in slots 2 through 5, enter:
prom -w 2:frediag.exe 2-5
More examples of command lines appear at the end of this section.
Note:
Once you enter the
prom
command
,
it must run to completion. The
control-c (abort) command is disabled for the duration of the
prom
command
execution to allow it to run to completion. Upgrading takes from 2 to 10
minutes per PROM. Verifying takes up to 2 minutes per PROM.
Caution:
When upgrading PROMs with new software, upgrade all slots that
contain FRE modules to avoid a mismatch of software.
