Intel Desktop Board DG31PR Product Guide Hardware Support Power Connectors ATX12V-compliant power supplies can turn off the computer power through system control. When an ACPI-enabled computer receives the correct command, the power supply removes all non-standby voltages. When resuming from an AC power failure, the computer returns to the power state it was in before power was interrupted (either on or off).
Desktop Board Features Instantly Available PC Technology CAUTIONS For Instantly Available PC technology, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply and/or effect ACPI S3 sleep state functionality.

Power-On Self-Test (POST) memory test begins and before the operating system boot begins. This chapter tells you how to update the BIOS by either using the Intel Express BIOS Update utility or the Iflash Memory Update utility, and how to recover the BIOS if an update fails.
Intel Flash Memory Update Utility You can obtain either of these files through your computer supplier or by navigating to the Desktop Board DG31PR page on the Intel World Wide Web site at: http://support.intel.com/support/motherboards/desktop Navigate to the DG31PR page, click “[view] Latest BIOS updates,” and select the ISO Image BIOS Update or Iflash BIOS Update utility file.
CD-ROM, bootable USB flash drive, or other bootable USB media. The utility available on the Intel World Wide Web site provides a simple method for creating a bootable CD-ROM that will automatically update your BIOS. The Iflash BIOS update files can also be extracted locally to your hard drive and copied to a bootable USB flash drive or other bootable USB media.
BIOS could be damaged. Due to BIOS size and recovery requirements, a CD-R with the .BIO file in the root directory will be required.
