Hi, J.D.:

I posted an i386/PC HAL package;
http://sourceware.cygnus.com/ecos/contrib.html has a pointer to it.  The
last time I updated it was the end of October, so don't be suprised if the
eCos source code has changed quite a bit--installation might not be as
straightforward as before.  I'm actually planning on updating to the
current CVS version next week.  Look out for a bug somewhere in the mutex
handling code: I'm sure it's related to the interrupt handler code.  Stay
tuned for that fix.  But in the meantime, that package allows you to
construct a GDB stub on a floppy disk, so you just boot from that and then
connect to the debugger from COM1.  If you have any significant problems,
just e-mail questions to this list, that way everyone benefits from the
discussion.  Cheers!
