3.4.6 System BIOS Cacheable
Allows the system BIOS to be cached for faster system performance.
3.4.7 Video BIOS Cacheable
Allows the video BIOS to be cached for faster video performance.
3.4.8 Video RAM Cacheable
This item lets you cache Video RAM A000 and B000.
3.4.9 8 Bit I/O Recovery Time
This option specifies the length of a delay inserted between consecutive 8-bit I/O operations.
3.4.10 16 Bit I/O Recovery Time
This option specifies the length of a delay inserted between consecutive 16-bit I/O operations.
3.4.11 Memory Hole At 15M-16M
Enabling this feature reserves 15MB to 16MB memory address space to ISA expansion cards that
specifically require this setting. This makes the memory from 15MB and up unavailable to the system.
Expansion cards can only access memory up to 16MB.
3.4.12 Passive Release
This function is used to meet the latency of the ISA bus master. Try to enable or disable it, if you have ISA
card compatibility problem.
3.4.13 Delayed Transaction
This function is used to meet the latency of PCI cycles to from ISA bus. Try to enable or disable it, if you
have ISA card compatibility problem.
3.4.14 AGP Aperture Size (MB)
Choose 4, 8, 16, 32, 64, 128, 256MB. Memory-mapped, graphics data structures can reside in the Graphics
Aperture.
3.4.15 CPU Host Clock
Choose Default, 66, 75, 83, 100, 103, 105, 110, 112, 115, 120, 124, 124A, 133, 133A, 140 or 150Mhz for
the external frequency of your CPU. You can select Default, 66, 75 or 83Mhz if your CPU is 66Mhz
FSB and select Default, 100, 103, 105, 110, 112, 115, 120, 124, 124A, 133, 133A, 140 or 150Mhz if the
CPU is 100Mhz FSB.
The 75, 83, 103, 105, 110, 112, 115, 120, 124, 124A, 133, 133A, 140 and 150 Mhz frequency are
optional.
