Here are the current Power Profiles that 11G BIOS exposes in BIOS setup. The Active Power Controller mode
is the default mode.
Static MAX DBPM Disabled ( BIOS sets P-State to MAX)

Memory frequency = Maximum Performance
Fan algorithm = Performance
OS Control
Enable OS DBPM Control (BIOS exposes all possible P states to OS)
Memory frequency = Maximum Performance
Fan algorithm = Power
Active Power Enable Dell System DBPM (BIOS will not make all P states available to OS)

PowerEdge R510 Technical Guide
ICH-10 In ACPI mode, OS has control of the power button. In non-ACPI
mode, SMI handler owns power button events.
ICH-10 The OS is able to configure the system to wake on the RTC
alarm.
ICH-10 ICH-10 24-bit power management timer is used.
ICH-10 Each host bus' PME# signal is routed to a separate general-
purpose event pin in the chipset. When a device signals PME#,
the system wakes (if necessary), the OS detects the event, and a
Dell defined ASL routine handles the event. Wake-on-LAN is one
example of a PME.
N/A This feature is not supported on this system since the S1 state is
not supported.
Processor MSRs This feature does P state transition under Windows
Processor MSR and This feature allows multiple C state support for Processor. This
ICH-10 registers feature works under Windows and any ACPI OS that understand
C states.
Processor/MCH 11G Servers are the most energy-smart servers that Dell ships.
and ICH-10 chipset In addition to P, C, and T states, BIOS exposes the Power
registers. Profiles to the OS. Each Power Profile has specific settings and
fine tunes the processor (MCH, IOH and South Bridge).
