This file patches the RAM disk to show the real size occupied - its no longer
100% full.

Changes made in 2.00:

Completely new and different implementation for the Os 3.9 RAM-Handler,
PatchRAM is now a permanent patch for RAM that comes in the form of a
patch-file.


Changes made in 2.00.2:

Added a new release of LoadModule.


Changes made in 2.00.3:

Added a new release of LoadModule (again)

Installation:

The installation of PatchRAM is a bit more trickier than it used to be
because it is a permanent patch and replaces the code within the RAM
handler directly.

0) Unpack the archive to wherever you want. Open a shell and change
the current directory to where the archive was unpacket.

1) Extraction of the RAM-Handler: This step requires the Os 3.9
"AmigaOs ROM Update" file and the "ExtractModule" program in this
distribution. Now enter on the command line:

version "DEVS:AmigaOs ROM Update"

2) The output of this command should be "44.57" or the patch cannot be
applied.


3) Enter the following command on the command line:

ExtractModule from "Devs:AmigaOS ROM Update" module 17 to ram:Ram-Handler

4) This command will place the RAM-Handler within the ROM-Updates file to
RAM:Ram-Handler. Now apply the patch to this file by entering the
following command:

spatch -oram:Ram-Handler.new -pRam-Handler.pch RAM:Ram-Handler

5) This command will generate the new RAM-Handler. Copy it now to "L:" by
entering the following command:

copy ram:Ram-Handler.new to L:Ram-Handler

6) You have now two alternatives how to make use of the new Ram-Handler. As
it is no longer part of the ROM-Updates file, it has to enter the system in
a different way. Alternative I) is to use the "LoadModule" command,
alternative II) is to mount it manually.


Alternative I): This will make the new RAM-Handler reset-resident in much the
same way as SetPatch did.

7) Copy the LoadModule command from this archive to C:

copy LoadModule to C:

8) Edit the startup-sequence with an editor of your choice. In the following,
let's assume the default system editor, "Ed":

Ed S:Startup-Sequence

9) 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:Ram-Handler NOREBOOT

10) 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:Ram-Handler LIBS:icon.library LIBS:workbench.library NOREBOOT


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).

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

SetPatch SKIPROMMODULES ram-handler >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,ram-handler >NIL:

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

13) 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.


Alternative II): Mounting the RAM-Handler by hand in a non-reset-resident
way.

7) Copy the the files "RAM" and "RAM.info" to DEVS:DosDrivers:

copy RAM RAM.info to DEVS:DosDrivers

8) Edit the Startup-Sequence with an editor of your choice. For the following,
let's assume you use the system editor "Ed":

ed S:Startup-Sequence

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

SetPatch SKIPROMMODULES ram-handler >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,ram-handler >NIL:


10) Press <RETURN> and insert the following commands *BELOW* SetPatch, one in
a line; note that it is important that these commands are run *AFTER* SetPatch
(different from alternative I):

Assign RAM: DisMount
Assign ENV: ENVARC:
Mount DEVS:DosDrivers/RAM
Assign ENV: Remove

11) To save the changes back when using "Ed", press <ESC>, then <X>, then
<RETURN>. This step depends on the editor you use, though.
