System BIOS Cacheable
This feature is only valid when the system BIOS is shadowed. It enables or disables the caching of
the system BIOS ROM at F0000h-FFFFFh via the L2 cache. This greatly speeds up accesses to the
system BIOS. However, this does
not
translate into better system performance because the OS does
not need to access the system BIOS much.

Enabled
(default).
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.
•
Disabled
(default).
•
Enabled.
Delayed Transaction
This feature is used to meet the latency of PCI cycles to and from the ISA bus. The ISA bus is a lot
slower than the PCI bus. Thus, PCI cycles to and from the ISA bus take a longer time to complete and
this slows the PCI bus down. However, enabling Delayed Transaction enables the chipset's embedded
32-bit posted write buffer to support delayed transaction cycles. This means that transactions to and
from the ISA bus are buffered and the PCI bus can be freed to perform other transactions while the ISA
transaction is underway.
This option should be
enabled
for better performance and to meet PCI 2.1 specs. Disable it only if
your PCI cards cannot work properly or if you are using an ISA card that is not PCI 2.1 compliant.

Delay Prior to Thermal
When you system temperature is high, you can set the DRAM access time slowdown between on
4 min – 32 min delay.

AGP Aperture Size (MB)
Select the size of Accelerated Graphics Port (AGP) aperture. The aperture is a portion of the PCI
memory address range dedicated for graphics memory address space. Host cycles that hit the aperture
range are forwarded to the AGP without any translation.
