MBSU v1.0
---------

MBSU: MagiC Boot Speedup Program
================================
This program updates MAGIC.RAM to speed up the MagiC boot process
by removing the floppy detection (seek/access) during booting.  It
should work with all 5.xx and 6.xx versions (and possibly earlier
ones too).  However, it has only been tested with v6.01 - make sure
you have a backup of MAGIC.RAM before running this program!

IMPORTANT: the patch has two versions: one that tells MagiC there
is one floppy drive, and one that tells MagiC there are two floppy
drives.  So, if you change the number of floppy drives attached
to your system, you will need to re-apply this patch each time.

DISCLAIMER
==========
I am advised to include a disclaimer because there are unreasonable
people out there.

"I make no warranty with respect to this documentation, or the program
it describes, and disclaim any implied/explicit suggestions of usefulness
for any particular purpose.  Use this program only if you are willing to
assume all risks, and damages, if any, arising as a result, even if it is
caused by negligence or other fault."


How to run MBSU.PRG
===================
1. Make a backup of the MAGIC.RAM file you are going to update!
2. Launch MBSU.PRG and you will receive two introductory alerts.
3. After continuing, you will get a file selector to allow
   you to choose the version of MAGIC.RAM to update.
4. When you have chosen a file, MBSU will tell you whether
   it is an original version, a patched version, or an
   unrecognised version/program.
5. You may choose to Update an original version or to Restore
   an already-patched version to the original.
6. After the update has completed, you will be prompted to
   repeat the above, starting at #3.


How it works
============
MBSU looks for the following hex string in an unpatched MAGIC.RAM:
	2078 047a 4e90 4a40 6606 2078 04c6 4e90 4e75
It then changes this to:
	31fc 000x 04a6 0038 0003 04c5 4e75 4e90 4e75
where x is the number of floppies you have (1 or 2).
To restore, it looks for the patched version and replaces it with
the original :-).
