You can reserve this area of system memory for an ISA
adapter ROM. When this area is reserved, it cannot be
cached. The user information of peripherals that need to
use this area of system memory usually discusses their
memory requirements.
Delay Prior to Thermal
4 Min

This BIOS feature is only valid for systems that are fitted
with Intel Pentium 4 processors with 512KB L2 cache.
These processors come with a Thermal Monitor which
actually consists of an on-die thermal sensor and a
Thermal Control Circuit (TCC).
When the Thermal Monitor is in automatic mode and the
thermal sensor detects that the processor has reached its
maximum safe operating temperature, it will activate the
TCC. The TCC will then modulate the clock cycles by
inserting null cycles, typically at a rate of 50-70% of the
total number of clock cycles. This results in the processor
"resting" 50-70% of the time.
As the die temperature drops, the TCC will gradually
reduce the number of null cycles until no more is required
to keep the die temperature below the safe point. Then the
thermal sensor turns the TCC off. This mechanism allows
the processor to dynamically adjust its duty cycles to
ensure its die temperature remains within safe limits.
You should not select a delay value that is unnecessarily
long. Without the Thermal Monitor, your processor may
heat up to a critical temperature (approximately 135°C), at
which point the thermal sensor shuts down your processor
by removing the core voltage within 0.5 seconds.
AGP Aperture Size

The AGP Aperture is a portion of the PCI memory address
range dedicated for graphics memory address space.
Cycles that hit the aperture range are sent to the AGP
without translation.

AGP
PCI Slot
This tells the BIOS where to look first for the display
adaptor. This should be set by default to AGP unless you
fit a secondary PCI card or completely disable the
onboard video adapter.
