BIOS setting Function Configuration options Effect
Enabled Enables this function SMRR support The SMRR (system management range register)
limits cacheable references of addresses in SM-
RAM so that code can be run in SMM (system
management mode).
In some circumstances, an intruder who is logged
on as administrator could configure the Intel
processor to gain access to the SMM. Enabling
SMRR reduces this risk of unauthorized access.
Disabled Disables this function
Enabled Enables this function
The processors are operated at different fre-
quencies to save energy.
C-States This setting allows the operating system to set the
processor clock speed on its own, thereby saving
energy.
Disabled Disables this function
Both processors are operated at the same fre-
quency.
Enabled Enables this function Enhanced C-States
2)
This setting allows the operating system to set the
processor clock speed on its own, thereby saving
energy.
Disabled Disables this function
Enabled If the ICH receives a bus master request, then
the system changes from the C3/C4 state to the
C2 state and the bus master is enabled auto-
matically.
C-State pop up mode This setting makes it possible to detect bus mas-
ter requests and assign processor clock frequen-
cies, thereby saving energy.
Disabled Bus master data transfer is a break event, and
the ICH will attempt to return to the C0 state.
Enabled If the ICH does not receive a bus master re-
quest, then the system will be reset back to the
C3/C4 state.
C-State pop down mode
3)
This setting makes it possible to detect bus mas-
ter requests and assign processor clock frequen-
cies, thereby saving energy.
Disabled The ICH will not attempt to automatically return
to C3/C4 state.
Enabled Enables this function
