:     I came across the following code:

: /* note this example will always write to the top

:  void writeString(int colour, char *string)
:  {
:   char *video=(char*)0xB8000;
:   while(*string!=0)
:   {
:    *video=*string;
:    string++;
:    video++;
:    *video=colour;
:    video++;
:   }
:  }

: But I can't get it to work, It just crashes. Anyone know how? I'm going to
