- The settings within the CPU are completely independant of the RAMSEY and
- RAM chips you may have and the settings of RAMSEY.
-
- The 68030 can selectively turn on or off BURST most for the caches.
- Due to an oversight, the 2.04 SetPatch does not turn on BURST mode.
- (This is the 68030 mode, nothing to do with the RAMSEY chip)
- You can turn on BURST mode by doing "CPU BURST"
