Thanks. It didn't even occur to me that there was a 640K
limit. I figured as long as it fit on a floppy it'd be OK.

I'll check that out. I guess I'll have to add a hard drive to
the target.
In the meantime, I can't even get a simple "hello world" app
(which is smaller than 640K) to generate any output. The
RedBoot floppy image generated with basically the same
configuration works fine, but hello world doesn't. :/
