INT 14h,  17h    Reboot system

      Entry:  AL         00h - "Cold boot"
                         01h - "Warm boot"

    Perform the old 3-finger salute.  Used in extreme emergency by code that
    can't seem to find a "clean" way out of the trouble it has gotten itself
    into.  Hopefully it won't happen while you're computing something in the
    other half of a DoubleDOS system. If your machine can make a distinction
    between a "cold" (power-up, self-test and boot) and a "warm" (just boot)
    bootstrap,  your FOSSIL should support the flag in AL. Otherwise just do
    whatever bootstrap is possible.
