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  
•  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 Desktop Board DG41TY page on the Intel World Wide Web site at:  
http://support.intel.com/support/motherboards/desktop
 
Navigate to the Intel Desktop Board DG41TY 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.
