PALBOOT:   This program installs a special bootblock which allows PAL
------     programs to be seen fully on NTSC Amiga's fitted with the
           SUPER AGNUS Chip.
                Code by Ziggy/Hysteria. Sydney, Australia.

For instance - if you have a bunch of EuroDemos which were written for
PAL/European video mode Amigas, you can't see about the bottom half
inch of the display since it's not properly displayed on American/NTSC
Amiga monitors.  Put your EuroDemos on a disk and run PALBOOT on that
disk which will install a special bootblock.  Now reboot on that floppy
and if you have the 1-Meg "Super Agnus" chip installed you'll be
flicked into PAL mode.  Then run your demos and they should display
properly so you can see the entire screen.  Should work for European
games too providing the boot blocks don't conflict with anything the
game requires.  After rebooting on a PALBOOT-written disk you may have
to diddle with your vertical hold monitor knob (usually on the front
of the monitor under a flip-down panel) in case the picture rolls.
This worked okay for me - check out STAR*FIGHT'S "SAMDEMO" in the library
for an example- using the PALBOOT  trick, you will now see all kinds
of messages and a neat little "LCD" display that Maurice built into his
demo which you can't see when running his demo in regular NTSC Video mode.

note: you also may want to adjust your monitor's vertical height control.
so you can see the whole picture. on my 1080, there is a hole in the back
that you can stick a flathead screwdriver in to adjust vertical height. on
my friend's 1084s monitor, it automatically configures itself for this
adjustment.
