    How to update to BIOS 5531?

    GhostRider

      Hi I have tried to update to BIOS 5531 on my DP55KG motherboard but I have not been able to do this successfully:

       

      1) BX10J.86A.5531.EB.EXE From Windows 7 64 Bit OS - reboots PC, normal boot sequence - no sign of BIOS flash - Logon Says BIOS update complete but checking BIOS it is still at old version 4905

       

      2) KG5531P.ISO Burn to CD, boot CD - BIOS fails to recognise CD - repeat download and burn to new CD - same issue

       

      3) KG5531P.BIO copy to flash drive, boot and use F7 - this simply causes PC to reboot - BIOS still at 4905

       

      I am not over clocking the Motherboard.

       

      Anybody any ideas? Maybe the first effort via the OS has somehow corrupted the BIOS so the F7 method fails?

       

      Many thanks

          You should make a bootable flash drive. In the flash drive you should have the iflash.exe and the bio file copied aside from the boot system. When you have the prompt, type iflash/pf xxxx.bio then press the enter key. Follow the onscreen instruction.

            I recently had the same problem. I used the opensource tool from "http://unetbootin.sourceforge.net/" to made a bootable USB stick with a DOS in a single step.

            -You need a stick with FAT32

            -Get the unetbootin tool, choose "distribution" and "Freedos", then let it run.

            -Copy via Explorer the iflash2 files and the .bio file on the stick

            -Boot from the stick, choose "Boot with no himem. and emm386 or so - second option in the Freedos boot menu IIRR.

            -Type C:<space><return>, the space seems to be important. Now you should be in the sticks root directory. dir<return> shows the contents.

            -iflash2 /p file.bio for flashing.

             

             

            Maybe this helps,

              That is what I have stated in general. To be specific, at the prompt, type: iflash2 /pf (space) filename.bio, then press enter. Follow the onscreen instruction.

               

              BTW: The original title of this thread is How to update to Bios 5531?. It is change to How to update to Bios 5531?Making bootable stick. The change starts with 4711/Skip's thread.

                Thanks for the suggestions Boyet and 4711.

                 

                I have tried the F7 method to install from the BIO on a USB stick, all that happens is the PC reboots and no BIOS flash happens. It seems quite involved to make a bootable USB stick, sorry if this sounds a silly question but do you think this will work better than the F7 method to use a BIO file? I am puzzled why the standard Intel methods are failing. What could be causing the issue e.g. is it a bad BIOS that I should not try to force on or is it just the installer is failing?

                  For making the flash drive bootable you can use the diskpart utility of Vista or Windows 7. I prefer using the bio file and booting with the flash drive in updating my bios.

                      Saw the update that BIOS 5531 appears to have disappeared from the download list for DP55KG.

                       

                      I did not attempt to update to 5531 after three different methods failed I decided the risk was too high to try and force an update. The release notes for the next release may give a clue if anything was wrong with 5531.
