I beg to differ here. I've got ASDG's 2M board in a Minirack C, and (of
course) I'm running VD0: (sized at about 1.5M as I remember).

When the ChangeKickStart program came out just after 1.2 was released I
was using it to reboot with 1.1 so I could play those brain-damaged
Electronic Arts games that required 1.1. (BTW, ChangeKickStart just does
a reboot that leaves you at the KickStart prompt.)

Every time that I went from 1.2 to 1.1 then back to 1.2, my VD0: was
still intact. I don't recall ever trying a ChangeKickStart from 1.2 to
1.2, but I don't see why that wouldn't work too.

If the KickStart process really does clear memory, it must be just the
512K of Chip RAM that gets blasted. As far as I can see there is no
write protect switch on my ASDG card. :-)
