    I don't know anything about EMU8086, but I think a little more information is needed before anybody can help you.

    In general, all you need is a memory address. Unfortunately, there are many different kinds of memory (conventional, high, upper, expanded, extended, physical, virtual, etc.), many different kinds of addresses (segment:offset, physical, linear, etc.), many different operating environments (DOS, Windows command shell, Windows GUI, Unix, etc.), and many other environmental factors (real vs. enhanced mode, paging, cacheing, VCPI, DPMI, BIOS compatibility, etc.) that affect if and how you can access different parts of memory.

    thank you,
    not too much complicated. a simple instance like DEBUG program in windows shell.

    cmd
    >debug
    -D 0:0 100

    which shows memory information from 0:0 - 0:100

    The D command under DEBUG is letting you look at RAM, which is what you say you want to do, so what exactly do you need help with?
