Well it isn't just on the 2000. Any Amiga (500's are being shipped w/ the 1 meg
Agnus chip) with the 1 meg Agnus chip can
switch into PAL mode. Using the program called PALBooter, you can boot as
if you were in PAL mode. There is a slight flicker (freq change?), but that is
all.

You do have to change to make sure you have the 1 meg Agnus chip. How do you
tell, you ask? Well you should have 1meg of chip ram if you have the fatter
Agnus (but not necessarily. I have the chip but 512k chip & 512k fast ram).
If you still don't know just try booting PALBooter. You will be able to tell
if it works.
