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.

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.
