I have a DH77EB mainboard which have problem.
The LAN chip cannot start automatically when I enter windows
the failure imformation is:(Code10)
To work normally ,need to disable and enable the LAN chip device in device manager
I know the problem is because the Intel ME(Intel management engine) firmware lost in the bios
I try to flash the bios to higher verison, but get failure
the information for the failure is :flashing image for intel management engine firmware failed 1550
I try to flashing ME Block via FPT tool,but cannot success,too.
And try to flashing bios via SPI hardware flasher ,but the problem still no resolve.
Who can help me to solute this problem,get back the ME FW to the bios. Or any other tips to solute this problem
Thank you for contacting the Intel community.
What operating system you have installed?
In this case, if you are having issues with the LAN, I suggest you t try to uninstall the driver and then reinstalling it?
You can download the latest LAN driver here:

https://downloadcenter.intel.com/download/23794/Intel-Gigabit-Ethernet-Network-Connection-Driver-for... Intel® Gigabit Ethernet Network Connection Driver for Windows 8*

I'm not sure what operating system you have installed, so I posted the drivers compatible with this motherboard based on the operating system compatible with your board.
If the problem persists, please let me know what BIOS version you have installed right now, I'm asking because if you have an older version and you try to install to the latest you could get a BIOS update failure, at that point I suggest you to update the BIOS in sequence to the latest version using the https://www.intel.com/content/www/us/en/support/boards-and-kits/desktop-boards/000005724.html F7 method.

I hope this can help.
No, once you are in this state, the only way to recover the ME is to install the latest BIOS using the Recovery Method. I also suggest you clear CMOS before you attempt this recovery.
