Trying to update BIOS DZ77GA-70K

Trying to do an F7 BIOS update via USB thumb drive, but I can't get the drive to be recognized in the F7 list, its showing only my installed hard drives. Should the USB thumb drive be installed into a specific USB port? Express update has never worked on my machine.

Thanks,

John

Hi John, you may want to try the back panel USB 2.0 ports and have the drive formatted as fat-32.

Thanks Joe, I did in fact try one of the top rear yellow USB 2.0 ports. Should it matter what port? I will try reformating and also try another thumb drive.

Thank you.

John,

 

First, to answer your question, which rear USB 2.0 port you use should not matter. There are some compatibility issues that can crop up with USB 3.0 ports, so I agree you should stay away from them.

 

Do you have Fast Boot enabled? One of the things that Fast Boot disables is USB detection. If so, try disabling this feature...

Thanks Scott,

Fast Boot was not enabled but I had to enable USB Boot. Once I did that it would read the flash drive but my BIOS update still FAILED. Same as when I tried to update using the .exe file. I am getting an error that flashing the Intel Management engine failed. So I'm stuck on the 039 BIOS unable to update...it should not be so hard, sorry.

Ah, that's the missing information I needed. You have the old ME firmware and it won't allow itself to be updated. In order to get the later BIOSs and later ME firmware installing, you need to do a BIOS recovery operation. The instructions for doing this can be found here: http://www.intel.com/support/motherboards/desktop/sb/CS-023360.htm?wapkw=bios+recovery http://www.intel.com/support/motherboards/desktop/sb/CS-023360.htm?wapkw=bios+recovery...

Thanks again Scott...Was hoping not to have to do that, a bit scary...but I'll give it a go. Would you say I should update to current BIOS in increments since I have a very early BIOS or should I just go to the latest? Also I assume since its a BIOS recovery that everything will be reset to defaults? Any potential problems to look for when I get back to Windows?

Really appreciate the help.

I would recommend that you do this in 2-3 steps. Install BIOS 45 first using the recovery process and then go to the latest BIOS in 2-3 steps using the F7 or EXE methods. There shouldn't be any issues with Windows, though it may re-enumerate devices on each reboot if you let it go all the way into Windows...

Scott,

Thanks for the help, now at BIOS 0066 though I had to do BIOS recovery each time as express BIOS always failed at the Intel ME engine.

Regards
