Hier versuche ich aus der originalen ZCN Doku eine etwas verständlichere Installationsanleitung zu machen:
* Installing ZCN
The installation guide below assumes you are installing from a Unix or
MS-DOS machine. It should be clear what to do on other machines
though; you just need to know how to XMODEM a file across, and how to
send a plain ASCII file. Normally the easiest way is to use a serial
comms program of some sort.
** Getting ZCN up and running for the first time
*** Saving your existing data
[If you don't care about using the ROM software, or don't mind losing
all the data in the internal memory, skip ahead to the next section,
`Booting ZCN via a Serial Link'.]
ZCN uses the NC100's 64k of RAM as more normal computers generally use
RAM - as an area to load programs into, and an area to use for
temporary workspace, etc. Unfortunately, this is not compatible with
the way the built-in software works, so you'll lose all your existing
data in memory unless you save it first. `rrinit' is a program which
lets you save your data like this. (You'll be able to restore it later
using `runrom'. More on that later on.)
To run `rrinit', you'll need a memory card of at least 128k in size.
It should probably be the card you intend to copy ZCN onto, but it
doesn't have to be. Bear in mind that the card will be reformatted in
ZCN's format, and any data currently on it will be lost!
You must also have at least one file stored in memory on your NC100,
as the ROM software doesn't let you do serial file transfers
otherwise. (If you haven't got any files in memory, just create a
small file with the word processor. It doesn't matter what's in it or
what it's called, just that it's there.)
Der Autor empfiehlt 2400 baud zu nutzen, das ist aber schnarch-langsam, deshalb habe ich 9600 ausgewählt.
Wichtig ist auch, dass der Software-Flow Control (die letzte Option im Menu (Handshake) auf NO gesetzt wird.
Dann geht man in den Texteditor auf dem NC100 und erstellt ein beliebiges Textdokument. Name ist egal, Inhalt ist auch Egal.
Ohne diesen Schritt kann der NC100 keine Dateien über die Serielle Schnittstelle empfangen, da er noch keine Dateien im Dateisystem hat.
Die weiteren Schritte, können 1 zu 1 aus dem Manual übernommen werden.
First you need to setup the serial link. You should set the baud rate
to 2400 9600 baud on the `remote' computer, as transfers seem to be a bit
hairy (for the ROM software at least) at higher speeds.
After that, *make sure there isn't any memory card in the NC100's
slot*, then do the following:
Key Reason
--- ------
Function + S go to terminal program
Menu, down*3, left*2, Stop use 2400 9600 baud, Handshake OFF
(you may need more or less lefts,
depending on the current setting)
<type a few characters on the NC100 and `remote' computer to check
the link is working ok>
<start XMODEM send (or `upload') of `rrinit.bin' on `remote' computer>
Stop quit terminal program
Function + L load document
Menu, T, M, rrinit, return XMODEM receive `rrinit'
<wait for transfer to finish>
Stop return to file selector
<now insert the memory card>
Menu, F, <possibly Y>, Stop format card (answer `Y' if it prompts you)
<make sure the `rrinit' file is the currently-highlighted one>
Menu, T, P, Stop write rrinit to memory card
Stop exit file selector
Function + X run rrinit
[NB: `rrinit.bin' is in the `bin' subdirectory.]
Almost immediately after you do the function-X, rrinit should say
"Snapshot written - press Stop". Pressing Stop then returns you to the
NC100's main menu.
Now you should be ready to run ZCN, so here goes...
*** Booting ZCN via a Serial Link
[If you are upgrading an existing version of ZCN, skip ahead to
`Installing a new version using an old one', which will be rather more
appropriate.]
First you need to setup the serial link. You should set the baud rate
to 2400 9600 baud on the `remote' computer, as transfers seem to be a bit
hairy at higher speeds. (ZCN itself can cope with file transfers at up
to 19200, but the ROM software seems to be more picky. So for this
transfer, it's best to stick with 2400 9600 and Handshake OFF.)
Now you should cold-boot the NC. Do this by turning it off and, while
holding down Function, Stop and `<-Del', turning it back on.
Next you should do the following:
(Note that if you're using an NC200 (the clamshell `notebook'), you
should transfer `zcn200.bin' instead of `zcn.bin'. See nc200.txt for
details of the NC200 support - this file mostly concentrates on the
NC100. Also bear in mind that the keypresses to transfer the file will
differ somewhat on that. :-))
Key Reason
--- ------
Function + S go to terminal program
Menu, down*3, left*2, Stop set speed to 2400 9600 baud
<type a few characters on the NC100 and `remote' computer to check
the link is working ok>
<start XMODEM send (or `upload') of `zcn.bin' on `remote' computer>
Stop quit terminal program
Function + N, x, return create junk document
x put junk in it
Function + L load document
Menu, T, M, tmp, return XMODEM receive `tmp'
<wait for transfer to finish>
Function + B enter basic
"*LOAD TMP 6000" load system (omit the quotes :-))
"CALL &6000" start ZCN (ditto)
[NB: `zcn.bin' is in the `bin' subdirectory.]
(It was necessary to create the junk file above so that Function-L
would work; there's no way to get the menu which lets you XMODEM
receive a file without any files in memory. Yuck.)
(Also, note that you will need a reasonably complete serial lead for
the ROM software's XMODEM transfer to work (this doesn't apply to ZCN
itself, which needs only the minimal out/in/gnd connection (plus CTS
if serial output is to work, though that can just be soldered to
RTS)). Any lead you *buy* should be fine, but if you've knocked up
your own only-three-pins-connected job you'll need to borrow a better
lead from someone for this transfer. 
However, for an alternative
approach, see `badlead.txt'.)
You should then end up with a screen looking something like:
ZCN v1.3 (2001-04-20 02:32) ROM v1.06
A>
A>
(The version numbers and date/time of assembly may vary - don't worry,
that's because I don't often update the above `screenshot'. Also,
the NC200 version will describe itself as "ZCN200".)
The `A>' is the ZCN command processor's prompt. It'll probably be
there twice because you pressed enter at the end of "CALL &6000" and
it was still pressed the first time ZCN prompted for a command line,
so it just prompted again. (ZCN didn't know that it was pressed before
- it wasn't running then.)
If you ran `rrinit' before booting ZCN, skip the next paragraph. Let
me put that another way - IF YOU RAN `rrinit', DO *NOT* DO `format a:'
OR YOU WILL LOSE THE DATA IT SAVED. (`format b:' etc. is fine,
though.)
Those of you who didn't run `rrinit' should now make sure you have
your PCMCIA card in the card slot, and type `format a:'. If it prompts
you asking if you want to reformat it, press `y'. You should see the
message `Formatting complete' almost immediately (formatting memory
cards is a very simple operation).
If the card you're using is 512k or 1024k, type `format b:', which
formats the 2nd logical drive (the 2nd 256k of the card).
If the card is 1024k, follow this by typing `format c:' and finally
`format d:'.
If the card is larger than 1024k, you've got more money than sense, as
the NC100 can't access the rest.
Now you can make a bootable ZCN drive on your card. Do this by typing
`sys a:'.
Since this is the first time you've added the system to this card,
you'll get lots of `addblk..' messages. This means that ZCN is moving
the whole logical drive up 1k (one block). This is necessary to ensure
that you can add a new version of ZCN to a card without having to
reformat it. If you ever want to add a new version of ZCN to the card,
you can just boot it via the serial link as you did here and then do
`sys a:' again. In fact, you can also do it without ever leaving ZCN -
see the section `Installing a new version using an old one' below.
When the message `copying...done.' appears, the card is bootable.
You may have noticed, while the system was being copied, there was a
rather curious small black bar at the bottom-left of the screen. This
is the `drive light' for logical drive A:. Whenever this bar appears,
part of the card's memory is paged in that belongs to that logical
drive, i.e. the `disk' is being accessed. The `drive light' for
logical drive B: is to the right of that, C:'s is to the right of
that, as is D:'s. It won't usually be `on' as much in general as it
was for the `sys a:' command; don't worry about this, it's perfectly
normal.
You should now check that the system is bootable. This gives you an
opportunity to learn the booting procedure. As the NC100 remembers
what you were doing when you turn it off, you should only ever need to
reboot the system from scratch like this to: 1. check bootable cards,
2. reboot after a crash, or 3. reboot after changing the lithium
backup battery. (When you change normal batteries, there's no need to
reboot - the backup battery takes over until the new batteries are
in.)
*** Rebooting to test a bootable card, or after a crash
Going from when the NC100 is still on, you should:
1. Press the on/off switch to turn the computer off. If it didn't turn
off, remove the main batteries (not the lithium one) and disconnect
from the mains adaptor, and then reinstall/reconnect. (The on/off
switch will work fine usually, but sometimes when the NC100 crashes it
stops working because of memory corruption.)
2. Hold down the Function, Stop and `<-Del' keys and press the on/off
switch. This restarts the machine from scratch.
Assuming you're now at the `enter time' screen or the main menu, it
doesn't matter which:
3. Make sure your bootable ZCN card is in the slot, and press
`Function' and `X'. This should boot ZCN and leave you at the `A>'
prompt.
An alternative method (for testing a bootable card) is to use the
`cboot' command.
