It would be nice if there is.
It is possible to reset the machine to factory default settings from the service processor. So you don't need Solaris for this task. Unfortunately if you want to change the configuration from the factory default, you will need Solaris. I'm working on code to make it possible to do so from OpenBSD though. Cheers, Mark
