______________________________________________________________________________

Changes made for 46.6:

Many. The whole resident MMU-setup was turned upside down, mostly to 
make it more compatible. MuMapRom has been successfully tested on
additional systems with the modifications in place.

Note that you may still need lots of chip mem in worst case.


Changes made for 40.4:

The reset-and-stay resident mechanism of MuMapRom makes now use of the
ColdCapture exec vector and a nice little extra hack.

Adds now a 16MB "safety zone" around memory areas to keep some wierd memory
tests working.

Did not work at all if the "ROMINFAST" option was not present at the
command line. Should be much better now.

______________________________________________________________________________

MuMapRom is a mmu.library based "ROM kicker", i.e. it replaces the ROM
resident kickstart by a disk based image file. The purpose of MuMapRom
is mainly to replace the kickstart image temporarely for testing, e.g.
for program authors to test their programs under different environments.
It should not be used for permanent kickstart replacement.
______________________________________________________________________________

Top reasons why not to use this program:

- It is a hack. MuMapRom assumes several non-granted behaivours of
  the current Kickstart implementation, of the CPU and motherboard
  hardware.
- MuMapRom will not work in all available environments. It may cause
  some compatibility problems, depending on the board type, the
  hardware and the memory configuration.
- MuMapRom requires a lot of chip memory (See "Implementation" for
  details why this is so). In fact, it will only run on machines with
  2MB chip memory. A graphic card is recommended as otherwise not
  much chip memory is left.


If you need a new/different ROM for your system, you should rather:

- Buy the ROM chip and install it. This will definitely work, will be
  most robust and won't cause any problem. If you need two different
  ROM versions, hardware solutions are available that allow switching
  between two ROMs.
- If you just need an upgrade of several system modules, other less
  hacky solutions exist. For example, to replace one ROM module by
  a ROM module of a later edition, you are encouraged to use the
  "LoadModule" and "MuProtectModules" of the same author.
- If you need short turn-around times for software testing, try to
  find a solution that is adapted to your board hardware 
  (e.g. CyberMap). These programs do not need to touch the MMU, but
  rather use board specific hardware for ROM remapping. This will
  typically do better since it will not require as much chip memory
  as this program.

If you still think that you "need" MuMapRom, please read the 
"MuMapRom.guide" file first. Experts might want to read the "Implementation"
chapter of the guide as well as it contains background information where
the MuMapRom restrictions arise from.

volume of information consisting of random data).


(ii) Distributing the Program on a CD-ROM, provided that

a) the Archive is reproduced entirely and verbatim on such CD-ROM, including
especially this licence agreement;

b) the CD-ROM is made available to the public for a nominal fee only,

c) a copy of the CD is made available to the author for free except for
shipment costs, and

d) provided further that all information on such CD-ROM is re-distributable
for non-commercial purposes without charge.


Redistribution of a modified version of the Archive, the Program or the
contents of the Archive is prohibited in any way, by any organization,
