ParNET Harddrive - AN INTRODUCTION (30 January 1995)
----------------------------------------------------
Written by Jason Smith
----------------------
ParNET was originally written by Vernon Graner in 1992 and all praise
should go to him with regards to this most useful program. All I've done
is simplified the files and tidied up the presentation a bit, where I felt
it was a little untidy and removed NETKEYS (as it crashed the NET:) and
this feature wasn't much use to me.
The idea of this version is to use Directory Opus instead of messing about
with Workbench windows copying and updating. It is harddrive based now
because of the disk swopping involved and because ParNET's main usage IS
with harddrives. ParNET now is more advantageous because this version
allows you to backup a harddrive, drawer or partition to another machine
easily and very cheaply. You can in fact UPDATE A BACKUP WHILST STORED
ONLY ON THE OTHER SYSTEM'S HARDDISK - WHICH OTHER BACKUP UTILITIES CANNOT
ALWAYS OFFER!!!
The other main reason for rewriting this is that thanks to a recent
magazine Directory Opus version 4 odd has just been made available on a
coverdisk so many of you might have it already. Hopefully!
I discovered when playing about with ParNET that Directory Opus not only
allows you to configure it so that buttons are set up for a network, but it
initialises each device as it requires it. This sorts out the problems I
experienced using mountlist modifications and means that you can select a
CD player or floppy drive etc as you require it and not having to
initialise them all and go through many cancel messages and that 'window'
unless you have a floppy or CD inserted on boot. It also sorts out the
icons which didn't always initialises properly.
Now as you select devices in Directory Opus they then will become visible
in NETWORK's main window when you SHOW ALL FILES, VIEW BY ICON! Until then
they won't. This method stops no disk - Retry or Cancel error messages and
causing you to have to keep editing mountlists as previously. You can also
do this via shell. Typing CD NET:DH0/ [RETURN] will initialise access to
the other machine's DH0: partition via DOpus or the 'window' as before.
However, one major advantage Directory Opus has over the 'window' is that
when it copies your files they copy with all settings as they WERE hence if
you copy a drawer of your Workbench to the other machine THE ICONS WILL
APPEAR IN EXACTLY THE SAME PLACES!!! This makes copying not only easy (as
you treat the NET: as a device) but makes this new version of ParNET a very
handy backup program.
I have a CD32 and SX1/85Mb HD connected via ParNET to my A1200 constantly
via a Parallel 4 way switch box. That way I can switch in ParNET or my
Laser or Epson printers without much connecting or risk OF BLOWING UP THE
MACHINE BY HAVING THE POWER ON AND CONNECTING THE CABLE!!! I can click on
NET:CD/ (in Directory Opus Device Setup) and access my CD32 as a CDROM
drive. Very efficient (and nice with an 85mb harddisk in both machines)
and much quicker and easier than that horrible, dear and slow network
method.
Although I haven't got any, if you don't have Directory Opus then try a PD
similar utility (see if that works) and set that up for ParNET. You need
a button to run the HOST or CLIENT script on the relevant machines and to
set up NETWORK devices.
Typical device set up (as like I've done in Directory Opus):
DH0:
DH1:
DF0:
DF1:
CD0:
and
NET:DH0/
NET:DH1/
NET:DF0/
NET:DF1/
NET:CD0/
I've included my ParNET DirectoryOpus.CFG configuration file. If you
replace the default when DOpus is on your harddrive (It goes in S) you
will have it all done for you. I've changed the colours from horrible red
and yellow to the same as XCopy Pro to all tie in nicely (I have a button
to boot this program from DOpus you see).
I will enclose a ParNET installation script with the files later. You can
manually install it with DOpus if I don't get to write one. Copyright
comments are included on the end of any ParNET files (when viewed in
Directory Opus) to make manual installation easier to add or remove.
My THANKS AND APOLOGISES go to Vernon Graner for such a wonderful program
and I hope you don't mind my modifications for easier use with harddrives.
I am submitting this in the will of PD - I originally wrote it for ME! I
won't make any financial gain as it isn't fair to. All copyright belongs
to Vernon on relevant files. I just hope all of you out there find it as
useful a program as I have.
READ THROUGH THE REST OF THIS DOCUMENT CAREFULLY ON THE CABLE.
If you don't understand it, a cable can be obtained from either of the two
mail order companies at the bottom of this page at your own risk. I have
no dealings with them!!! I just use them like anyone else and found them
to be good - so far.
---------------------------------------------------------------------------
I WON'T BE HELD RESPONSIBLE IF YOU DAMAGE YOUR MACHINE(S)
a) Not reading the docs carefully and not really knowing what you are
doing.
b) Wiring up the cable wrongly (even if you do know what you are doing).
c) Plugging in the cable when the power is on OR an unmodified 25 way one.

SIMPLE BUILD YOUR OWN CABLE DOCS - Written by Jason Smith

DIAGRAM 1
---------
Through wires = 2-9, 11-13 and 18-22
Cut wires = 1, 10, 14-17, 23-25
Bridge = Leave pin 13-13 and disconnect pin 10 (as above).
Now bridge pin 10 to pin 13 with thin wire at BOTH ENDS.
TIP - CUT PIN 10'S WIRE LONG SO PIN 10 IS SOLDERED, READY TO
BRIDGE.
TO MAKE IT CLEAR (2-9) OR (14-17) FOR EXAMPLE MEANS PINS
2, 3, 4, 5, 6, 7, 8, 9 OR 14, 15, 16, 17 AT BOTH ENDS OF THE CABLE.
NOT CONNECT PINS 2-9 OR 14-17!

VERY VERY IMPORTANT:
--------------------
AT (* AND ALSO AT #) BRIDGE PIN 10 TO PIN 13 WITH THIN WIRE AT BOTH ENDS
OF THE CABLE.
(PIN 10 IS CUT AT BOTH ENDS OF THE CABLE).
(PIN 13 IS LEFT CONNECTED AT BOTH ENDS OF THE CABLE).
TO MAKE IT CLEAR (2-9) OR (14-17) FOR EXAMPLE MEANS PINS
2, 3, 4, 5, 6, 7, 8, 9 OR 14, 15, 16, 17 AT BOTH ENDS OF THE CABLE.
NOT CONNECT PINS 2-9 OR 14-17!
---------------------------------------------------------------------------
CHEATING, BUT LOOK BEFORE YOU LEAP MR. LEMMING!
-----------------------------------------------
If not linking A500+/A600/A1200/CD32+SX1 then double check the cable connectors still FIT in your Parallel Port.
The easiest thing to do is to buy a PREMADE CABLE WITH ALL 25 LINES
PASSED AND DB25 CONNECTORS ON BOTH ENDS (BUT REMEMBER TO DOUBLE CHECK THE
DB25 CONNECTORS FIT YOUR PARALLEL PORT(S) BEFORE YOU BUY THE CABLE!) and
then open it carefully and CUT those wires which are not supposed to be
connected. You also need to BRIDGE PIN 10 TO PIN 13 as per DIAGRAM 2
above (ON BOTH ENDS OF THE CABLE).
REMEMBER THAT: PIN 10 IS CUT AT BOTH ENDS OF THE CABLE.
PIN 13 IS LEFT CONNECTED AT BOTH ENDS OF THE CABLE.
AS YOU DO THE BRIDGING BIT OF PIN 10 TO PIN 13 AT BOTH
ENDS OF THE CABLE! (See DIAGRAM 2)

WARNING!!!! - READ IF YOU WANT YOUR COMPUTER TO STILL FUNCTION.
---------------------------------------------------------------
** NEVER PLUG IN AN UNMODIFIED CABLE BETWEEN THE TWO COMPUTERS! **
** DOUBLE CHECK YOUR CABLE BEFORE INSTALLATION! **
** CHIP ALERT!!! - DISCONNECT ANY SERIAL CABLES BEFORE USE!!!! **
** NOT CONFIDENT? - I ADVISE YOU OBTAIN A CABLE VIA MAIL ORDER. **
TWO GOOD SUPPLIERS ARE BELOW (...AND IT MAYBE CHEAPER ANYWAY!)
