Have you or anyone you know ever debugged code that executes before the machine loads the boot blocks from the disk? If so, I would really like to know how it is done. I am trying to load ReAnimator's "Modem Nub" into the sys heap, setting D0 to 'nuSI' and all that good stuff, but having no luck! Please post or write! I could use the help! Brian Topping
