     Comments     : If  you  are  booting  with  a CHAOS infected disk the
                    virus  tries to allocate 2254 bytes chip memory. After
                    that  it  copies  itself into this address and changes
                    the CoolCapture to stay resident in memory. 

                    To  infect  other  disks the virus patches the DoIO()-
                    Vector  from  the exec.library.  Every Bootblock looks
                    different because it is coded with a byte depending of
                    $DFF006.

                    Every 8.th  infection  the virus FORMATS your disk and
                    the following alert appeares:
                    "CHAOS! by Tai-Pan. Number of Diskformats: XXX"
