After Debian install, XMS and HIMEM errors prevent Win95 launch.

[Robert Cymbala <cymbala@lafn.org>]

This Symantec knowledge-base solution applies equally to GNU/Linux,

    ... just replace "Norton SystemWorks" with "GNU/Linux" ...

Was able to "fix" by turning off power, unplugging a few things and
then power-up.  Lo and behold, Win95 came back, like it had a new
life-support system or something.

  Error: "HIMEM.SYS is missing..." or "Error: Unable to control A20
          line..." After Installing Norton SystemWorks

  Situation:

        You installed Norton SystemWorks and restarted the system. Now
        Windows displays the error message:

        "HIMEM.SYS is missing. Make sure that the file is in your
                   Windows directory."
        or
        "Error: Unable to control A20 line. XMS driver is not installed."
