How do you find all the interrupts called by a dos program using DEBUG on the command line. I know it probably has something to do with the Search function but whenever I trying something like -s 100:ffff(which i think searches the entire memory segment for “INT”) But when I manually Unassemble through the same segment with the u command I can see INT/interrupts being called.
I think you need a better debugger, but if you want to use DOS debug to find INT call, you can try something like:
First, you find the right segment to search for (by entering d command), then you search in that segment for CD (this is machine code for INT mnemonic). You can disassemble the search result by entering u command.
