I've been doing some painfully slow debugging, mainly putting for
(;;); loops in various parts to see if it hard hangs or goes
nuts. So far it looks like it enters boot2(). initio(), which
appears functionally unchanged from 1.6, clears the screen.
That's odd, but it doesn't appear to be what sends the code over
the edge. As far as I can tell it goes berserk on the first printf
statement (print_banner()).

I've tried commenting bits out and sticking in loops to see where
things go awry and I can't make sense of the results. printf's,
bios2dev(), awaitkey() all cause resets. I've gotten all the way
down to loadfile() in exec.c from boot2() to bootit() with enough
commenting, and that produces the same wild monitor sync hang as
the printfs. It seems to me that it may not be a problem within
boot2, but rather a manifestation of some previous error.=20

Cheers,
Steve
