To Install the Solaris 7 Operating Environment
● Install the Solaris 7 operating environment on your system.
Refer to the Installation Library shipped in your Solaris 7 media kit. As the Solaris 7
operating environment is installed, you will be notified whether the flash PROM in
your system needs updating. Installing this Solaris release will provide the software
that can upgrade your system’s flash PROM to the required level.
Making the Flash PROM Write-Enabled
Before you update the OpenBoot firmware contained in the flash PROM, you must
set a jumper to the write-enable position (Sun Ultra 1 and Ultra 2 systems) or set the
front panel keyswitch to the proper position (Sun Enterprise 450 system and the Sun
Ultra 450 workstation).
The Sun Ultra 1 and Ultra 2 systems, which do not have a front panel keyswitch, are
equipped with jumpers on their motherboards that allow the flash PROM to be
either write-protected or write-enabled. The default position is for the flash PROM
to be write-protected. To update the flash PROM, you must change the jumper to the
write-enable position.
