Memory Problems with DOS VM

    In standard DOS the area above 604k was reserved for video memory, boot rom/bios and adapters requiring I/O.

    Now that I have DOS fullly loaded, I am trying to optimize the memory for best results.

    The problem is that Parallels is taking up all the memory between 640K and 1M. Typically Video memory was 8-32K, but parallels maps 128K of memory for video.

    Is there any way to change this?

    Second it takes up another 128K for ADAPTER Space above that and the the Bios & Boot ROM take up the rest.

    This means there is no way to enable EMS memory because there is no room for a page frame of 64K.

    Any ideas... Anyone at Parallels even read the forum????

    I'm having the same problem, too, except that I want to use QEMM (one of my favs from the DOS era) rather than HIMEM/EMM386.

    Has anyone come up with a solution and not posted it? Its pretty frustrating.
