- The question was about setting caches for a CSA Mega-Midget Racer. Setpatch
- may set the caches for A2620/30s and for A3000 and A4000 systems but it cannot
- set the caches for the MMR. SETPATCH runs long before the MMR initialization
- program. Either SETCPU (for 1.3) or CPU (for 2.0 and up) should be used to
- change the cache states with the MMR. SETCPU was included with my MMR
- utilities disk but nothing was explained about using it. I run CPU in my
- user-startup to enable instruction and data caching and to copy the kickstart
- kickstart rom to 32 bit DRAM (I have a MMU in my MMR).
