Boot Dos3.3 progs/games from .dsk image on HD? (REAL IIgs)?

[n9yty@bigfoot.com (Steven Palm)]

Okay, it's all coming together now. ;-)

I have the ROM3 IIgs set up with 5MB of RAM and a 340MB Hard drive.  No
accelerator (yet?), but it's working pretty well.

My question:  Is there *ANY* way to use disk image files without having to
write them to a disk first?

I'd love to boot up some older applications, games and the like, but I
don't want to have to write them out to disk.

I have looked (briefly) into FocusDOS, which allows you to make a large
file that contains many disk images, but since you can't get to those
images from outside of FocusDOS, I don't know how to move files into
them.  I can't see the hard drive's other partitions when inside FocusDOS.

I also briefly saw some mention of OzDOS, but I don't know if that's a
workable solution either.

Surely, someone has been through all of this already.

(Imagine that, I want to actually play the games on the real hardware, not
an emulator. :-)

On the brighter side of things, I have WordPerfect and AppleWorks up and
running, and am eventually going to hook it into the MacOSX box with PPP
to get it "on the net".  Pretty cool stuff, I think.
