Short:    Update Os 3.9 BB2 Shell to 45.8
Uploader: thor@math.tu-berlin.de (Thomas Richter)
Author:   thor@math.tu-berlin.de (Thomas Richter)
Type:     util/boot
Version:  45.8
Requires: Os 3.9 BB2, Shell 45.7

This patch fixes two bugs of the 45.7 shell that was published with BB2.
You *must* provide the Os 3.9 BB2 to apply this patch. Please read the
FAQ below *carefully* before resuming.
_____________________________________________________________________________

Version 45.8:

Fixed handling of backticks within comments. They are now
properly ignored.

Fixed handling of equal-signs within arguments. They are
now considered similar to blank spaces and consider
following double-quotes as function, not as literal.

Some frequently asked questions:

Q: How official is this distribution?

A: As official as I could make it. There will be no future BB for Os 3.9,
but I still wanted to provide an update. Hence, here we go. Both, Amiga
and H&P agreed to my conditions, therefore this patch is fully legal.


Q: What about customer service and support?

A: There is absolutely no support and no warranty. You are welcome to
ask questions, but please direct them to me (see my email above) directly.
Neither H&P nor Amiga will provide any service or support or warranty
concerning this product.

If you do not agree with these limitations, you must not install this update,
and must remove the patch and the archive containing the patch from your
storage device immediately.

Installation:

Please double-click on the "Install" icon. This program will extract
the shell from the AmigaOs ROM-Updates file, will patch it and place
the resulting shell to the L: drawer. Further, it will copy the
LoadModule program to C:. 

You also will have to make some modifications on your startup-sequence.
The installer script will open an editor to allow you to modify
the startup-sequence, and will print the required instructions. 
Unfortunately, these instructions have to be carried out by hand and
cannot be automatized easily. Please follow the instructions
closely. For convenience, I repeat them here:


1) Locate the "SetPatch" command within the startup-sequence, place the
cursor on the "S" of "SetPatch" and press <RETURN>. This will insert a new
blank line ON TOP of SetPatch. Move the cursor upwards into this blank
line and enter the following command:

LoadModule L:Shell-Seg NOREBOOT

In case you are using LoadModule already, please add L:Shell-Seg as one of
its arguments. You may also load additional modules here, i.e. the Os 3.9 
icon.library or the Os 3.9 workbench.library. Just give their full paths 
as arguments to the LoadModule command. 
*NOTE THAT IT IS IMPORTANT THAT LOADMODULE IS RUN BEFORE SETPATCH*. 
With these modifications, the command line could look like this:

LoadModule L:Shell-Seg L:Ram-Handler LIBS:icon.library LIBS:workbench.library NOREBOOT

(This is one line, no line feed intended)
The advantage of "LoadModule" is that the ROM modules loaded by
this command can be protected from getting overwritten by means of 
the "MuProtectModules" program of the same author (not included in this archive).


2) Locate the "SetPatch" command within the startup-sequence. Move the cursor
behind "SetPatch", and add the command line option "SKIPROMMODULES shell"
to the command. The setpatch command line should then read approximately as
follows:

SetPatch SKIPROMMODULES shell >NIL:


If you already have to skip parts of the update, as for example the scsi.device,
the line should rather look like this:

SetPatch SKIPROMMODULES scsi.device,shell >NIL:

3) Save the changes of the startup-sequence back. For "Ed", press first <ESC>,
then <X>, then <RETURN>.


4) To make the changes active, a reboot is *NOT* enough. You should turn
off the machine, wait for half a minute, and reboot. This will flush the
RAM resident parts of the ROM-Updates mechanism.
