I have often pondered doing a processor specific DEBUG. There is or was a DEBUG out there a gentleman wrote that could get you started, but I can't recall the name of it. It ran on top of DOS, but all the code was there and was 32 bit too. I will have to look at my archives when I get home this evening. I'll post the name this evening, maybe it will help.

Sorry, I got distracted. I will send myself a note at home to look through my archives. I can't seem to find a link on the net.

Ok, I found it: http://members.tripod.com/~ladsoft/dos/grdbdl96.zip Get Real DEBUGGER IIRC, you can convert it fairly easily with FASM and then embed it into your own OS. I hope this helps.
