    Hi everybody,
    I'm new to this forum as I am using Parallels 15 only for one month now. I'm not a total noob to IT things, though.
    One problem I can not solve, and could not find anything about in the forum is the memory management in MS-DOS.

    For a specific program I need EMS memory (not XMS). I was configuring it just normally in the config.sys like I did 30 years ago.
    DEVICE=C:\DOS\HIMEM.SYS
    DEVICEHIGH=C:\DOS\EMM386.EXE RAM 1024
    Yet, MS-DOS claims to have no EMS at all, just XMS. The "mem" command confirms: no EMS.

    On start-up I get the error message:
    WARNING: Unable to set page frame base address--EMS unavailable (in MS-DOS 6.22)
    or
    EMM386 not installed - unable to set page frame base address (in MS-DOS 7.1)

    What do I do wrong?
    Thanks for your help!!
