Since the features in this section are related to the chipset on the CPU board and are completely
optimized, you are not recommended to change the default settings in this setup table unless you are
well oriented with the chipset features.
Selecting Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh, resulting in better
system performance. However, if any program writes to this memory area, a system error may
result. The default value is ―Disabled‖.
Enabling this feature reserves 15MB to 16MB memory address space to ISA expansion cards that
specifically require this setting. This makes the memory from 15MB and up unavailable to the
system. Expansion cards can only access memory up to 16MB.
