Updating the Flash PROM on the
Ultra 1, Ultra 2, Ultra 450, and Sun
Enterprise 450 Systems
This chapter describes how to update the flash PROM on the Ultra™ 1, Ultra 2, Ultra
450, and the Sun™ Enterprise™ 450 systems.
Some systems require a 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 within a single flash PROM for the Ultra 1, Ultra 2, Ultra 450,
and the Sun Enterprise 450 systems.
Note –
Only those systems identified in this chapter and the following chapter need
the flash PROM upgrade.
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.
