Intel Desktop Board DG33BU Product Guide Updating the BIOS with the ISO Image BIOS Update File or the Iflash Memory Update Utility You can use the information in this section to update the BIOS using either the Iflash Memory Update Utility or the ISO Image BIOS update file. Obtaining the BIOS Update File You can update to a new version of the BIOS by using the ISO Image BIOS update file (recommended), or Iflash BIOS update file. The ISO Image BIOS update file is a standardized image of a bootable CD-ROM that can be used to create a bootable CD that will update the BIOS. The Iflash BIOS update file is a compressed file that contains the files you need to update the BIOS. The Iflash BIOS update file contains: • New BIOS file (including the Intel® Management Engine Firmware Image) • Intel® Integrator Toolkit Configuration File (optional) • Intel Flash Memory Update Utility You can obtain either of these files through your computer supplier or by navigating to the Desktop Board DG33BU page on the Intel World Wide Web site at: http://support.intel.com/support/motherboards/desktop Navigate to the DG33BU page, click "[view] Latest BIOS updates," and select the ISO Image BIOS Update or Iflash BIOS Update utility file. Updating the BIOS with the ISO Image BIOS Update File The ISO Image BIOS update allows for the update of an Intel® Desktop Board BIOS to the latest production release regardless of the operating system installed on the computer's hard drive and without the need to remove the BIOS configuration jumper. It requires a blank CD-R, a read/writeable CD drive, and software capable of uncompressing and writing the ISO image file to CD. The image uses ISOLINUX* bootloader and automatically launches a script to upgrade the BIOS via the Iflash utility. 60
