The information on Atari Forum Wiki seems straightforward and correct.
There are indications though that different OS's play funny tricks on the user:
While my TT can boot MagiC 6.20 from a full 512 meg partition, my Falcon sticks to 256 megs for booting MagiC.
Other peoples' Falcons do likewise or different from mine.
Don't expect any similarities to be guaranteed there. ;-)
