10.1.1Special Considerations for Systems With 450 MHz CPU Modules

If you plan on installing either the Solaris™ 2.5.1 or Solaris 2.6 operating environment, you must install it using the Operating Environment Installation CD included with your new system. During the installation process, this CD installs certain software upgrade patches that support these Solaris releases running at the 450 MHz CPU speed.

These patches are not required if you are using Solaris 7 or later software.

The system’s OpenBoot PROM revision level must be 3.17 Version 0, or later, to run a 450 MHz CPU module. The OpenBoot PROM revision level is displayed in the banner at the top of the screen when you boot the system, or from the OpenBoot prompt you can display the banner by typing.
