PROBLEM

    Andrea Arcangeli found a bug in my atx motherboard.  The  powerbug
    allow you  to shutdown  the machine  running some  malicious code.
    Following info was taken from:

        http://www.cs.unibo.it/~arcangel/powerbug/powerbug.html

    The  power-bug  is  a  "feature"  of  some  atx  motherboards that
    power-off the machine running some piece of software code.   After
    the power-off you need to wait  some minutes before to be able  to
    power-on again.

    Tests showed that the bug show itself only at 233Mhz (or more) and
    using SDIMM and not other kind of ram that is placed on SIMM.   To
    test if your motherboard is bugged Andrea organized two test  that
    should show you the  bug.  The two  tests come with ABSOLUTELY  NO
    WARRANTY, to the extent permitted by applicable law.  No  warranty
    if  some  of  these  two  tests  will damage your hardware or your
    software.  Run it only at your own risk.

    - If you use linux you  only need to download file from  following
      address, extract it and then run `make`

    - If you are  not using linux you  must install linux and  goes to
      the  point  before  or  install  DOS  and run the `poweroff.bat`
      script that you will find in this other file.  This DOS  version
      of the test will boot linux so after running `poweroff.bat`  you
      will need to reboot in order to return in DOS.   For this go to:
