This power-cycling flushes any old firmware code out of system memory.
If you set the
auto-boot?
NVRAM configuration variable to
true
, and the
boot-
device
variable contains the device or device alias where the Solaris 7 operating
environment was installed, then the system will boot the Solaris 7 operating
environment. This concludes the flash PROM update procedure.

Enterprise Server Systems
If you previously removed the write-protect/enable jumper, you must reinstall it in
order to successfully perform the flash PROM update procedure.
boot-file
Empty string If you were booting a customized kernel file before the flash
PROM update, and
diag-switch?
was false (default), the
customized kernel file might not be booted after the flash PROM
update.

If you had a different sequence of boot-devices specified, after
the flash PROM update an incorrect device might be booted.
use-nvramrc? false

use-
nvramrc?
was set to true, then those customized commands
might not be used after the flash PROM update.
nvramrc
Empty If you had customized commands in the
nvramrc
, then those
customized commands might be lost after the flash PROM
update. Do not use
setenv
to change the
nvramrc

Instead use
nvedit
and
nvstore
. If you know that the
nvramrc
variable contains a firmware patch which is no longer
compatible with the newly programmed firmware, do not
change the
nvramrc
variable to its previously customized
value.

oem-logo?
might be

oem-banner?
was true before the flash PROM update, the
oem-banner might be lost after the flash PROM update, and
