     Comments     : The  BLACK  KNIGHT  virus is a very simple boot-virus.
                    When  you  are starting it, it copies itself always to
                    the  same memory address ($7F300). 

                    After copying the virus changes the CoolCapture-Vector
                    to stay resident in memory. Then the virus patches the
                    DoIO()-Vector to infect other disks.

                    There is a crypted message in the bootblock which says
                    decrypted:

                    BLACK KNIGHT (12/11/91)
