Configuring shadow memory
You can enable video BIOS shadowing or configure shadowing for specific option ROM memory blocks.
Note
For the best system performance, always leave the System shadow and Video shadow options set to Enabled (the default setting).
Your computer can access RAM faster than ROM. The options on this screen allow your system to copy the contents of its video ROM and any optional ROMs into RAM. When you use shadowing, your system can perform certain operations faster, providing a significant increase in performance.
Note
Some option ROMs cannot be shadowed; see the documentation that came with your optional equipment for information on shadowing the option’s BIOS ROM.
Configuring the advanced chipset
You can change values in the chipset register to optimize performance. However, to avoid possible configuration problems, it is a good idea to leave these options at their default settings.
