CPU Feature
Thermal Management
This setting specifies the thermal technologies implemented in the Pentium M
processor.
TM2 Bus Ratio / TM2 Bus VID
These settings specify the multiplier and VID values used by the processor
in TM2 (Thermal Monitor 2) mode.
Limit CPUID MaxVal
This setting controls the Max CPUID extended function value.
C1E Function
This item allows you to enable/disable the C1E power management feature
which can drop clock speed and voltage on the processor.
Execute Disable Bit
Intel's Execute Disable Bit functionality can prevent certain classes of mali-
cious "buffer overflow" attacks when combined with a supporting operating
system. This functionality allows the processor to classify areas in memory
by where application code can execute and where it cannot. When a mali-
cious worm attempts to insert code in the buffer, the processor disables
code execution, preventing damage or worm propagation.
Virus Warning
The item is to set the Virus Warning feature for IDE Hard Disk boot sector
protection. If the function is enabled and any attempt to write data into this area
is made, BIOS will display a warning message on screen and beep.
