pcnfs.arc.Z (or nfs-kit,arc on clarkson) is the PD and NDIS drivers for
Sun's PC-NFS. So if you want to run Sun's PC-NFS on a packet or NDIS driver,
yes, you need it.

>2) If so, where can I get it?

sun.soe.clarkson.edu - file drivers.arc are the packet drivers. nfs-kit.arc
are the Sun pc-nfs drivers.

>4) What is so special about the pc-nfs specific packet driver?

They are not "pc-nfs" specific. Any software written to the packet driver
spec will run over the packet drivers. PC-NFS (Sun), PC/TCP (FTP's) and
WinQVT are three different programs that USE the packet drivers to
communicate with the ethernet card.

It calls the FM function (F^%&# Magic :-). A packet driver passes info via a
software interupt that is assigned when installing the packet driver (see 
the drivers.doc file that comes with the packet drivers).
