Updating the Flash PROM on the
Sun Enterprise 3x00, 4x00, 5x00, and
6x00 Systems
The steps in this chapter describe how to update the flash PROMs in your Sun
Enterprise 3x00, 4x00, 5x00, or 6x00 system.
Some systems require higher level of OpenBoot™ firmware in the flash PROM to
run the 64-bit mode of the Solaris™ 7 operating environment. The OpenBoot
firmware is contained in several PROMs that are located on several different boards.
The flash PROM devices, which contain OpenBoot, are electrically erasable and
writable devices. This means that the firmware can be updated without removing
the flash PROM from the system board. This Solaris 7 kit includes the routines and
instructions you need to update the flash PROM in your system.
Determining If the Flash PROM Needs
Updating
Note –
If your system is an Ultra™ Enterprise™ 10000, you do not need to do this
update because the Ultra Enterprise 10000 does not have a flash PROM.
Only sun4u systems that can run the 64-bit mode of the Solaris 7 operating
environment might need the flash PROM update. Systems that can only run the 32-
bit mode (such as those in the sun4c, sun4d, and sun4m platform groups) do not
require updated firmware to run Solaris 7 software.
