     Comments     : The  Megamaster-virus  is a very  simple and stupid
                    one. If  you are  booting with an infected disk the
                    virus only  copies itself  to address $7F300. After
                    copying  the virus  sets the  coolcapture-vector to
                    the virusvalue  to stay  resdient in memory. In the
                    virusbootblock  you can  read: "MGM89"  (see alias)
                    There are two  crypted areas: a GFX-Message-Routine
                    and the  infection  routine.  To infect other disks
                    the virus uses the DoIO()-Vector. Sometimes, during
                    a reset,  the virus decryptes the GFX-Area and show
                    this message:

                                       Surpise!!!
