If this option is enabled, an alarm message will be displayed when trying to

CPU L1 and L2 Cache
Cache memory is additional memory that is faster than conventional DRAM
(system memory). CPUs from 486 -type on up contain internal cache memory,
and most, but not all, modern PCs have additional (external) cache memory.
When the CPU requests data, the system transfers the requested data from
the main DRAM into cache memory, for even faster access by the CPU. These
allow you to enable (speed up memory access) or disable the cache function.
