There is a program, called OZDOS, which will allow you to format a 3.5 
disk as two DOS 3.3 volumes (drive 1 and drive 2), and the thing is 
bootable. It contains a modified DOS and a modified FID. Seems to work 
well. Of course, if you boot that disk, you would be in DOS, not ProDOS. 
Also, Copy2Plus does not recognize an OZDOS 3.5 disk (no doubt that is 
the reason for the modified FID).

I do not know whether there are hard disk systems (other than SIDER) on 
which you can have a DOS partition. But, even with the SIDER, you have to 
use either DOS or ProDOS, not both at the same time. If there were a way 
to do it, someone in the W.A.P. would have figured it out by now, and 
would have told the rest of us.

BTW, Dave, greetings from the High Desert. Our friend, Burr, has moved 
back to Ridgecrest.
