- Short: Patch RAM to show right size, and more...
- Author: thor@einstein.math.tu-berlin.de (Thomas Richter)
- Uploader: thor@einstein.math.tu-berlin.de (Thomas Richter)
- Version: 1.21
- Type: util/boot
- Requires: OS 2.04 or better.
-
- This file patches the RAM disk to show the real size occupied - its no longer
- 100% full. Furthermore, it increments the stack size of the RAM task a bit,
- which seems to be *very tight*.
-
- ****** IMPORTANT NOTE: DUE TO INTERNAL CHANGES, THE PROGRAM MUST NOW *********
- ****** RUN BEFORE THE RAM DISK IS USED. THIS IS A FUNCTIONAL *********
- ****** DIFFERENCE TO FORMER VERSIONS *********
-
- The feature of allocating large RAM blocks reverse has been removed and is
- now integrated into PoolMem - which can be found in util/boot, too.
- ____________________________________________________________________________
-
- Changes made in 1.21:
-
- - Increased the stack size of the new RAM supervisor task by a few
- bytes because it was low on stack.
- - Auto-increments the stack size of the main RAM task on startup
- because this used to be too low as well... )-:
- ____________________________________________________________________________
-
- Changes made in 1.20:
-
- - Removed the reverse memory allocation feature and integrated
- this in PoolMem. Removed, therefore, some command line arguments
- that don't make sense anymore.
-
- Changes made in 1.11:
-
- - Added command line options, see below.
- - Added a different patching mechanism on request.
-
- Changes made in 1.10:
-
- - Fixed a bug that actually broke the reverse memory allocation
- feature. Sigh.
-
- Changes made in 1.09:
-
- - PatchRAM replaces no longer the AllocVec() function completely.
- Thus, the patch might be slightly (almost unnoticably) slower,
- but is compatible to AROS. Thanks to Jörg Strohmeier for the
- report.
-
- Changes made in 1.08:
-
- - Streamlined the code a bit.
- - PatchRAM can now be run anywhere in your startup sequence.
- It loads the RAM disk in case it is not available.

- Synopsis:
-
- PatchRAM PORTPATCH/S
-
-
- PORTPATCH: If given, use a different patching mechanism for the RAM
- disk disk info bug. The "PORTPATCH" might be slightly
- faster, might cause less compatibility problems with
- programs that somehow mess with the port lists and the
- reply ports, but is itself not without its quirks, too.
- It uses the undocumented PA_ACTION¹ type for the RAM disk
- port to capture the broken dos packets. The problem is
- that this message port type has never been officially
- documented, but is working since the very first release
- of the system, though.
- This patched port might - or should (!) - make your virus
- scanner scream!
-
- _____________________________________________________________________________
-
- ¹ For all the picky folks: Yes, I KNOW that this type isn't called
- PA_ACTION indeed, but since no official name has been assigned to this
- mode and it is often referred to as PA_ACTION, I keep this name for
- "traditional reasons".
- _____________________________________________________________________________
-
- Installation:
-
- Add PatchRAM to your startup sequence. This program MUST NOW BE RUN
- BEFORE THE RAM-DISK IS STARTED OR IT WILL FAIL. NOTE THAT THIS
- IS DIFFERENT FROM FORMER RELEASES.
- A good point is here:
-
- SetPatch ;*** NOTE THAT THIS IS DIFFERENT FROM FORMER RELEASES
- PatchRAM ;insert below this line, probably with options...
