Description
Enabling this feature allows the caching of the motherboard
BIOS ROM from F0000h to FFFFFh by the processor's
Level 2 cache. This greatly speeds up accesses to the
BIOS.
However, this does not translate into better system
performance because modern operating systems like
Microsoft Windows XP do not need to communicate with
the hardware via the BIOS. Current operating systems
make use of drivers to access the hardware directly.
Therefore, it would be a waste of the Level 2 cache's
bandwidth if the motherboard BIOS was cached instead of
data that are more critical to the system's performance.
In addition, if any errant program writes into this memory
area, it will result in a system crash. Therefore, it is highly
recommended that you disable this feature for better
system performance.
