Exactly! On a PC to run any code (even a rom debugger) enough resources have to be there to nearly boot it. besides for hardware debug there are POST and other codes. Of course if someone wanted a debugger in rom most PCs still socket the BIOS roms. it's a matter of codeing it up and adding the needed device interfaces. On the whole not that useful. Allison
