CrossDOS was included with 2.1.
Though
fat95 will work with 2.0 and (supposedly)even 1.3.
From fat95 readme:
Purpose
=======
"fat95" is a DOS handler to mount and use Win95/98 volumes just as if they were
AMIGA volumes.
System requirements
===================
* every AMIGA, OS 1.3+ (OS 2.0+ for full functionality)
* a suitable device file for low level disk access, like the
mfm.device for floppies.
