Kill2090 v1.0 By John Davis, 26/08/1990

Includes source code.

What it does
------------

KILL2090/RESET  are  a  set  of  programs to reset the amiga thru software
(first  asking  the  user for confirmation), plus it will try to _DISABLE_
ALL  the  autoconfig devices in your machine.  Since this will include the
hard-disk  controller, this allows you to safely run software off floppies
without  worrying  about  viruses  etc  getting at your autoboot/automount
hard-disk.

If you have the 1mb Agnus, it will also toggle your machine to PAL or NTSC
screen  mode,  depending  on  which  version  you use (useful for games if
you've  got a PAL machine and useful for gaining screen area if you've got
a  NTSC  machine).   If you ONLY wish to reboot to a different video mode,
then  the  RESET  version  will  do  that  alone  (without  disabling your
hard-disk etc).

Since  the  actual  screen toggle code is run from the cold capture during
reboot,  this  means  it  will  work  even  with games which have a custom
bootblock  (and hence can't have Nico Francois' PAL/NTSC bootblock used on
them).

In  spite  of the name, it will actually work with ALL autoconfig boards -
that includes the 2090a controller, the A590 hard-disk and ram system, the
2058/2052 ram boards and hopefully most 3rd party autoconfig devices.

When  you reboot you should notice a pause, then the led will blink on/off
5  times  and  the  screen will go pink.  This lets you know Kill2090's at
work.

If  you've  run  KILL2090,  when  it's  finished, you should get the amiga
asking  for  a workbench disk - your auto-boot hard-disk and all expansion
memory  is  now  disabled.   If  you've run RESET your machine should just
reboot to the chosen video mode.
