3.2.3 Memory Cache
This setting allows you to tweak the various cache settings for optimal performance of
your system. Press Enter to display the various cache settings.
Cache System BIOS Area
This feature is only available when the system BIOS is shadowed. It enables or
disables the caching of the system BIOS ROM at F0000h-FFFFFh via the L2
cache. This greatly speeds up accesses to the system BIOS. However, this
does not necessarily make the system perform better because the OS does not
need to access the system BIOS often.
As such, it would be a waste of L2 cache bandwidth to cache the system BIOS
instead of data that are more critical to the system's performance. In addition, if
any program writes into this memory area, it will result in a system crash. So, it
is recommended that you write protect this area for optimal system performance.

Write Protect
Cache Video BIOS Area
This feature is only valid when the video BIOS is shadowed. It enables or
disables the caching of the video BIOS ROM at C0000h-C7FFFh via the L2
cache. This greatly speeds up accesses to the video BIOS. However, this does
not necessarily make the system perform better because the OS bypasses the
BIOS and uses the graphics driver to access the video card's hardware directly.
