[SunRescue] Boot prom incantations on SparcStation 4/330?

[BSD Bob the old greybeard BSD freak]

Anyone have the correct booting incantations for a SparcStation 4/330
crate?  I want to try booting Solaris 2.4 from the cdrom.  I am
expecting it will be something like  boot sd(0,6,0) or boot sr(0,6,0),
but I am not all that sure from memory, and all my sundocs are in deep,
deep storage, so deep I could not locate them.  I did find the CD, though.

Thanks

Bob
