Installation guide

If you perform this upgrade, your HP system can no longer boot. Only a blank black screen with
a ashing underscore cursor is displayed.
Workaround: Do not upgrade HP Vectra XU Series systems with the latest BIOS Version
GG.06.13 to the Solaris 10 release. This version no longer supports these systems.
You can still boot your system by using the boot diskette or boot CD because the boot paths do
not use the hard disk code. Then select the hard disk as your bootable device instead of the
network or CD-ROM drive.
SPARC: Older Firmware Might Need Boot Flash PROM
Update
On SPARC based systems, Solaris 10 OS runs in 64–bit mode only. Some Sun4U
TM
systems
might need to be updated to a higher level of OpenBoot
TM
rmware in the ash PROM to run
the OS in 64-bit mode. The following systems might require a ash PROM update:
■
Ultra
TM
2
■
Ultra 450 and Sun Enterprise
TM
450
■
Sun Enterprise 3000, 4000, 5000, and 6000 systems
The following table lists the UltraSPARC systems and the minimum rmware versions that are
required to run the 64–bit Solaris 10 OS. System type is the equivalent of the output of the uname
-i command. You can determine which rmware version 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-2 3.11.2
SUNW,Ultra-4 3.7.107
SUNW,Ultra-Enterprise 3.2.16
If a system is not listed in the previous table, the system does not need a ash PROM update. For
instructions to perform a ash PROM update, see any edition of the Solaris 8 Sun Hardware
Platform Guide at
