First up, I'd like to say that my post was not intended to be a flame, it may have
come over more grouchy than I'd intended because I wrote it *Very* early
this morning after being up all night with stomach flu. So if anyone was offended
I'd like to appologise in advance.

The problem is that to use the port as it stands you need.
1) An HP
2) A network card.
3) Another host to network off that supports NFS, TCPIP and BPF.
Really we should only need 1). I have 5 computers capable of networking
(in addition to the HP) running MacOS, tripos, OS/2 and Solaris if I can't do
it easily who can?

What is the story about this? I tried to get some information on BPF from a
number of sources and the consensus seems to be that it is a tool for packet
monitoring on the network (ie used for debugging). If the rboot stuff is now
well understood why is BPF still needed.

The number of computers was not supposed to be a dig, I have several machines at
home (at least 5 "modern" systems and countless working 8 bit
machines doing all sorts of minor tasks). I agree with you about if it works use it.
My point was that the netload option only realy works if you are in a computer
rich environment. If you're not then you have problems. The fact that the
installation method IS netbooting (as opposed to a media based boot) emphasises
that the originators of the port are in a computer rich environment.
What I would ask is this. Suppose you pulled a 380, 9144 and a 7958 out of a skip
but had no access to any other computer, can you load the OS?

Ok to quote my managers lets look at your "opertunities" :-)
> But, the combination of a flaky HP-IB tape drive,
Is this flaky as in a bad unit or is this a unit design problem? Being in
Europe I can't help with a bad unit (other than point out a shop in Montreal
Canada with lots of 9144's) but analysis of the design of the tape drive
may be possible once I've sorted out my logic analyser.
> a very short supply of usable tapes,
The same store in Canada has lots of SH tapes too. Better than that I know of a
place in England with boxes and boxes of NEW HP 1/4" tapes marked
"Preformated for use on HP systems" So far I haven't picked any up because
it doesn't say WHICH systems. If you can send me the HP part numbers for the
useable tapes I will send you some new ones if they are ok and it helps the effort.

That I can't help with. :-)

About the HP tapes. Does anyone know what the story is?? Are the mechanisms
the same as standard QIC02 1/4" drives (ie are they only formated diferently) or
are ther actual hardware differences? Does anyone know if it's possible to format
standard 1/4" cartridges to allow them to work in place of the rare HP ones?

Thanks I'll look into this.

I'm serious, but to be honest I was more intent on an HP hardware FAQ
than a NetBSD one. The reason is that a HW FAQ is principly a compilation
and editing effort since no one person can have access to all the available
hardware anyway. Software FAQ's realy need the author to know a lot about
the software because he WILL receive questions about it. In a lot of peoples minds
the FAQ editor IS the expert on that subject. Until I have more familiarity
with NetBSD I wouldn't realy feel comfortable as FAQ editor.
HOWEVER I would be willing to do the donkey work of compiling and
maintaining a HP300/NetBSD FAQ if someone with more experience
proof read and co authored it.
