[comp.os.minix] Debugging Minix on a Zenith

Strictly speaking, this might not really be properly directed to this
newsgroup.  However, I'm not sure WHO it goes to, and probably someone
here knows the answer.

The Zenith 200 series has a built in ROM monitor, known as MFM-200.  It
has several built in features, among them a subset of the Microsoft Debug
features.  In debugging the Minix Operating System, I have need to be able
to put code in bootblok to interupt to this debug code.  Anyone know how
to do it?  Yes, I know that a CRTL-ALT RETURN will do it.  But that is
pretty coarse-grained. I'd like to put an in-line instruction in Bootblok
to do the same thing. (Like, for example, "int  03h").  What I REALLY need
to do is to be able to go to the same place that CTRL-ALT RETURN goes to!

Any help will be humbly and gratefully accepted.  Please e-mail replies:  I
doubt this is of general interest.
