BIOS Setup
NB Power Management
Dynamic clock gating for IOC/NT/MCU/CFG. The options are Auto,
Enabled and Disabled.
Memory Hole
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.
System BIOS Cacheable
When this field is enabled, accesses to the system BIOS ROM ad-
dressed 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.
