Summary: Dos 2.0 already works double density!


	I have used Dos 2.0 (unmodified) with double density drives thru
an ATR8000 in the double density mode.  Most of the double density drives
and their mods will automatically switch to the correct density upon
boot-up.  Atari Dos 2.0 gets notified of the appropriate density and then
has no problem.  Mydos, though, will additionally handle the situation
where you want to switch disks of different density where Atari Dos 2.0
fails.  Bill Wilkinson of OSS (and an author of Atari Dos 2.0) published a
book called Inside Atari Dos containing the Dos SOURCE code and
explanations of how it can handle double density drives.  So, just put a
double density disk in and boot-up!
