CACHE           - turns on all caches
BURST           - turns on burst mode for both data and instructions
NOCACHE         - turns off all caches
NOBURST         - turns on burst mode for both data and instructions
DATACACHE       - turns on data cache
DATABURST       - turns on burst mode for data
NODATACACHE     - turns off data cache
NODATABURST     - turns off burst mode for data
INSTCACHE       - turns on instruction cache
INSTBURST       - turns on burst mode for instructions
NOINSTCACHE     - turns off instruction cache
NOINSTBURST     - turns off burst mode for instructions
COPYBACK        - activates copyback mode
NOCOPYBACK      - de-activates copyback mode
EXTERNALCACHE   - activates external cache
NOEXTERNALCACHE - de-activates external cache
FASTROM         - with a processor having a supported MMU, copies the
                  system ROM into 32-bit RAM, making access to operating
                  system functions significantly faster. CPU then
                  write-protects the RAM area so that
                  the data cannot be changed.
NOFASTROM       - turns off FASTROM
TRAP            - this option is for developers only.
NOTRAP          - this option is for developers only.
NOMMUTEST       - allows the MMU settings to be changed without checking
                  to see if an MMU is currently in use.
CHECK           - the CHECK option, when given with a keyword
                  (68010, 68020, 68030, 68040, 68881, 68882,
                  or 68851, MMU, FPU) checks for the presence of
                  the processor indicated by the keyword.
