Is there a good low-level debugger for DOS machines that will take over
the system when it crashes?

I am thinking of something like motorola's Macsbug, which has been
extensively improved on the Apple Mac.

Basically, it needs to run as an alternative to DOS when it is executing,
rather than using DOS, it needs to disable interrupts (so it must
poll the keyboard), and it should take over the machine when a crash
is detected.  It would be nice to be able to get into it with ctrl-alt-del
or the hard reset switch.

All the DOS debuggers I have seen are not suitable for debugging any
thing like communication software or device drivers.

It would be nice, if all the above were satisfied, if it had built-ins for
displaying the system data structures.

Let me know if it works with MS Windows or not; I can go either way, but
it would be nice to have one that worked with it.

Please e-mail your responses and I will post a summary.

Thanks,
