BIOS Setup
3.1.3.8 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.
3.1.3.9 Video BIOS Cacheable
As with caching the system BIOS, enabling the Video BIOS cache will
allow access to video BIOS addresssed at C0000H to C7FFFH to
be cached, if the cache controller is also enabled. The larger the range
of the Cache RAM, the faster the video performance.
3.1.3.10 Delay Prior To Thermal
This field is used to select the time that would force the CPU to a
50% duty cycle when it exceeds its maximum operating temperature
therefore protecting the CPU and the system board from
overheating to ensure a safe computing environment..
3.1.3.11 AGP Aperture Size (MB)
This field is relevant to the memory-mapped graphics data of the
AGP card installed in your system. Leave this in its default setting.
3.1.3.12 Memory Parity Check
Select Enabled if the DIMM you are using supports parity. When the
system boots, it will add parity check during the boot-up memory
test to check the accuracy of transmitted data.
