Solaris 7 3/99 Online Release Notes (SUNWrdm)

SPARC only: Sun UltraSPARCTM System (sun4u) May Need Boot PROM Upgrade

If you want to run the 64-bit Solaris operating environment on an UltraSPARC system, you may need to upgrade its Open Boot PROM firmware. The Solaris 7 installation programs have a new checkbox for adding 64-bit support. This new 64-bit support is selected by default when installing on Sun UltraSPARC systems.

Note -

If you choose to run the 32-bit Solaris operating environment on any Sun or UltraSPARC system, the Open Boot PROM upgrade is not needed.

The following table lists the UltraSPARC (sun4u) systems that are affected and the minimum firmware versions needed. "System type" is the equivalent of the output of the uname -i command. You can tell what firmware version you are currently running by using the prtconf -V command.

System Type from uname -i

Minimum Firmware Version from prtconf -V
