Solaris 9 9/05 Release Notes

SPARC: Sun UltraSPARC System (`Sun4U`) Might Need Boot Flash PROM Update

Note –

If your system is already running 64-bit ready firmware, then the flash PROM update is not required.

If you want to run the 64-bit Solaris software on an UltraSPARC^TM system, you might need to update the system's flash PROM firmware. The Solaris 9 9/05 installation programs enable you to add 64-bit support. This 64-bit support is selected by default when you install on Sun UltraSPARC systems. A 64-bit system only boots in the 64-bit mode by default if the CPU speed is 200 MHz or greater.

Note –

If you choose to run the 32-bit Solaris software on any Sun^TM or UltraSPARC system, the flash PROM update is not needed.

The following table lists the UltraSPARC (Sun4U^TM) systems that are affected and the minimum firmware versions that are needed. System type is the equivalent of the output of the uname -i command. You can determine which firmware version that you are running by using the prtconf -V command.

Table 1–1 Minimum Firmware Versions Required to Run 64–Bit Solaris Software on UltraSPARC Systems


System Type From `uname -i`	Minimum Firmware Version From `prtconf -V`
SUNW,Ultra-1-Engine	3.10.0
SUNW,Ultra-1	3.11.1
SUNW,Ultra-2	3.11.2
SUNW,Ultra-4	3.7.107
SUNW,Ultra-Enterprise	3.2.16

Note –

If a system is not listed in the previous table, the system does not need a flash PROM update.

For instructions on how to perform the flash PROM update by using the Solaris CD, refer to the Solaris 9 on Sun Hardware Collection. You can obtain the manual at http://docs.sun.com.
