PhoenixBIOS Setup Utility Advanced Power Boot Exit Memory Cache Item Specific Help Main Controls caching of system BIOS area.

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. Uncached / 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 47 http://www. TYAN. com 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. As such, it would be a waste of L2 cache bandwidth to cache the video 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. Uncached / Write Protect Cache Base 0-512K This feature allows you to control caching of 512K base memory. Uncached / Write Back / Write Through / Write Protect Cache Base 512K-640K This feature allows you to control caching of 512K 640K base memory. Uncached / Write Back / Write Through / Write Protect Cache Extended Memory Area This feature allows you to control caching of system memory above one megabyte. Uncached / Write Back / Write Through / Write Protect Cache A000-AFFF/B000-BFFF These features allow you to control caching of A000-AFFF/B000-BFFF memory. USMC Caching / Disabled / Write Through / Write Protect / Write Back Cahe C8000-CBFF/Cache CC00-CFFF These feature allows you to control caching of C8000-CBFF/CC00-CFFF memory.
