     Comments     : If  you are booting with a GREMLIN-Virus infected disk
                    disk  the  virus  copies  itself  to $7F400. To infect
                    other  disks  the  virus  patches  the  DoIO()-Vector.
                    Additionally the virus changes the CoolCapture to stay
                    resdient  in  memory.  Finally  the  virus patches the
                    SumKickData-Vector from the exec.lib.


                    If a value reaches 20480 the virus executes an endless
                    routine  &  shows some colors.  After the 16.th reboot
                    the virus gives out a GFX-Message. (Red Screen + White
                    Letters)  and  you  will  get  the  following  graphic
                    message on your screen:
