CPU - Displays information about the CPU of the computer
CACHE/S, BURST/S, NOCACHE/S, NOBURST/S, DATACACHE/S, DATABURST/S, NODATACACHE/S, NODATABURST/S, INSTCACHE/S, INSTBURST/S, NOINSTCACHE/S, NOINSTBURST/S, COPYBACK/S, NOCOPYBACK/S, EXTERNALCACHE/S, NOEXTERNALCACHE/S, FASTROM/S, NOFASTROM/S, TRAP/S, NOTRAP/S, NOMMUTEST/S, CHECK/K
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.
