NFS for Personal Iris?

[Paul Linton]

Being that I "inherited" the responsibility of a Personal Iris I was
trying to find out some info.  I installed a new OS (received in December
or January) which I was later told by SGI was sent to us by 'accident'.
Do I have to call someone and specifically ask for updates (sort of like
IBM and its PC/RT)?  

Anyway, nowhere on the installation tapes could I locate any NFS type
stuff.  Is this purchased separately?  What do I need to do to get it
if it's not?

Thanks,

   Paul
