System BIOS Cacheable
The setting of Enabled allows caching of the system BIOS ROM at
F000h-FFFFFh, resulting in better system performance. However, if
any program writes to this memory area, a system error may result.
Memory Hole At 15M-16M
In order to improve performance, certain space in memory can be
reserved for ISA cards. This memory must be mapped into the memory
space below 16 MB. The choices are Enabled and Disabled.
