DellDell PowerEdge R310 Technical Guide 46Table 13. Power Management Features on the R310Feature Type Enable/Status/Ctrl bitlocationDescriptionACPI modeswitchFixed PCH The OS uses the SCI_EN bit to switch from legacy mode toACPI mode.Sleep states Fixed PCH Supported states: S0 (Working), S4-OS (‗Hibernation‘ in W2K),and S5 (Soft-off).S1 (also called ‗standby‘ or ‗suspend‘) and S3 are notsupported.Power Button Fixed PCH In ACPI mode, OS has control of the power button. In non-ACPI mode, SMI handler owns power button events.Real-TimeClockFixed PCH The OS is able to configure the system to wake on the RTCalarm.Power Mgmt.TimerFixed PCH 24-bit power management timer is used.Power Mgmt.Event (PME)Generic PCH Each host bus‘s 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.USB wake Generic N/A This feature is not supported on this system since the S1 stateis not supported.DBS N/A Processor MSRs This feature does P state transition under WindowsC StateSupportN/A Processor andPCH registersThis feature allows multiple C state supports for Processor.This feature will work under Windows and ACPI OS thatunderstand C states.Power ProfilesupportN/A Processor/IMCand PCHchipsetregisters.11G Servers will be the most energy smart servers that Dellwill ship. In addition to P,C and T states, BIOS will expose thePower Profiles to the OS. Each Power profile will have aspecific settings and it will fine tune processor, MCH, IOH andSouth Bridge. For detailed explanation on how this featureworks, please look at BIOS Power Management specificationlocated in Design Docs under R310 engineering.Here are the current Power profiles that 11G BIOS will expose in BIOS setup.
