Specifying cache memory settings
Using the memory cache can increase speed of access to data. When the memory cache
is enabled, recently accessed data is stored in SRAM, which is faster than regular
memory. Before accessing data in the regular memory, the CPU checks the cache. If the
data is not held in the cache, the CPU accesses regular memory as usual.
To specify cache memory settings, highlight Cache Memory in the Advanced menu and
press Enter. The following screen is displayed:

If you don’t want to cache the system BIOS, choose
uncached. Please note that system performance may
decrease rapidly as a result.
