SUMMARIZE: how to find PROM version w/o reboot

I got lots of response--more than I care to enumerate--and I like to
thank everyone you took the time to answer my enquiry. You know
who you are.

There are two ways to do get the PROM version:

1) The obvious one is to get to the PROM with stop-A and run the
'banner' command. Altho' this is safe--provided you don't run any
other command and exit (with 'go') as soon as possible--I'm pretty
nervous about this method, esp. if you have mission critical
applications, valuable data, and lots of users who need to access
those apps & data. Which bring us to

2) Run 'prtconf -V'. This command was what I was looking for. I had
originally ran it with w/o the '-V' but got a long listing of device
tree. The '-V' option, which works only on sparc arch, will return
a string with PROM version #.

NOTE: Since I'm running Solaris 2.5x, I didn't have the opportunity to
method 2 with other versions. Some people have pointed out the 'prfconf
might not work on them. FYI.

Also, this topic is also in the list archive. Not verified by me.
