System BIOS Cacheable
When this field is enabled, accesses to the system BIOS ROM
addressed at F0000H-FFFFFH are cached, provided that the cache
controller is enabled. The larger the range of the Cache RAM, the
higher the efficiency of the system.
Memory Hole At 15M-16M
In order to improve system performance, certain space in memory
can be reserved for ISA cards. This memory must be mapped into
the memory space below 16MB. When enabled, the CPU assumes
the 15-16MB memory range is allocated to the hidden ISA address
range instead of the actual system DRAM. When disabled, the CPU
assumes the 15-16MB address range actually contains DRAM
memory. If more than 16MB of system memory is installed, this field
must be disabled to provide contiguous system memory.
