MuFastZero will remap the zero page of the RAM, which usually contains
the autovectors for interrupts, from ChipMem to FastMem. It will *NOT* change the
vector base register because this might result in certain incompatibilities.
It moreover replaces FastExec, which is really a bad hack, by providing a
method to relocate a chip memory based exec and expansion library to fastest
memory and hence speed up the system even more. For that, the "preparation"
tool "MuMove4K" must be run, which is contained in this archive. "MuMove4K"
replaces also the ShapeShifter "PrepareEmul" tool by something smarter.
Last but not least, MuFastZero can be told to remap the supervisor stack
to Fast memory as well.
-----------------------------------------------------------------------------
Changes in release 40.21.1:
MuFastZero remained unchanged, but MuMove4K was bumped to release 47.1.
This release of MuMove4K includes the following changes:
If all system resources are out of the low chip memory area, MuMove4K performs
now only minimal action to preapre the system for emulation, or exits
immediately. This may prevent a reboot on Os 3.1.4 or above as exec reserves
there sufficient memory anyhow. The 47.1 also fixes one defect when scanning
the devices system list.

This tool is part of the MMULib distribution. To find out more about the
mmu.library and its goals, download util/libs/MMULib.lha.
------------------------------------------------------------------------------
Quick installation notes:
- Copy LIBS/mmu.library to LIBS:
- Copy MuTools/MuFastZero and MuTools/MuMove4K to C:
- If you want the FastExec feature, run "MuMove4K" in front
of "SetPatch". Add the "PREPAREEMUL" option if you want to
make use of the ShapeShifter. Add "NOREBOOT" if SetPatch V44
reboots the system on startup anyhow.
- Run MuFastZero in C: with the desired options.
- Read the MMU.Guide and MuFastZero.guide/MuMove4K.guide as soon
as you've some time.
