3.1.3.4 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.
15M - 16M
Disabled
3.1.3.5 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.
3.1.3.6 Init Display First
This field is used to select whether to initialize the AGP or PCI
first when the system boots.
AGP When the system boots, it will first initialize the
AGP.
PCI Slot When the system boots, it will first initialize PCI.
The CPU assumes the 15-16MB memory range is
allocated to the hidden ISA address range instead
of the actual system DRAM.
The CPU assumes the 15-16MB address range
actually contains DRAM memory. If more than
16MB of system memory is installed, this option
must be selected to provide contiguous system
memory.
