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 Intel Mobile Board MGM45WU page on the Intel World Wide Web site.
Navigate to the Intel Mobile Board MGM45WU page. Under the “Software and drivers”
heading, click on “Latest BIOS” to locate the latest BIOS files. Click on the “BIOS
Update” link and select the ISO Image BIOS Update file or the Iflash BIOS Update file.
Updating the BIOS with the ISO Image BIOS Update
File
The ISO Image BIOS update allows for the update of an Intel
®
Mobile 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.
