However if I use # pmode/dj, isn't there a way to malloc a chunk of memory and somehow # detect the physical address of this chunk? I'm not sure about this, actually. We're running using CWSDPMI, not PMODE, and that's been working for us. # DOS with himem.sys installed and WITHOUT EMM386 is the only # environment I am really interested in. That's how we're running too. We *can* run with EMM386 - but only poorly. It allocates memory from the top down, which is the worst thing possible for building scatter/gather tables. # and I have no idea what that is good for i.e. what I need the # physical_map function for. # Any hints? I'm afraid that I personally wasn't the person on our team working on this code; the main guy who was is no longer at the company (but he may be reading this list anyway *ping*). My life is spent up in app-space :) Charles Sandmann would probably be the right person to talk to about this for details.
