I don't have anything older than 1.2, but I'm thinking even more basic
than that. The IBM PC has enough smarts to scan adaptor ROMs, check for a
floppy disk, and if neither have an OS, go to ROM BASIC. I just figured
the Amiga's simple boot code would check for an expansion board with an
attached drive, if none is found, scan for a disk in DF0, if none is
found, put that image in the screen showing a kickstart disk. Guess it
doesn't work that way :(

That is interesting to know about 1.0 though.

I knew there were special daughter boards, but didn't know that it was
that simple.

I know, the Amiga is the first system where I had to have 3 drive minimum
to not loose my sanity. I had workbench in one, a MS-DOS disk in another
(because I started out downloading stuff from the net and transfering it)
and my "destination" disk in the third. I had to have the utility to
decompress files somewhere too, with two disks I kept running into
problems where my destination disk would be swapped out for something else
while I was trying to write the decompressed files to it, it took quite a
bit of juggling to work, 3 drives made life much easier!
