Short:    Patch RAM to show right size
Uploader: thor@einstein.math.tu-berlin.de (Thomas Richter)
Author:   thor@einstein.math.tu-berlin.de (Thomas Richter)
Type:     util/boot
Version:  1.20
Requires: OS 2.04 or better.

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

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 1.20:

	- 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.
	A good point is below a line like this:

makedir RAM:T
PatchRAM		;insert below this line, probably with options...


So long,
	Thomas
