Hi,

I don't exactly know what you mean, sorry. Is there a part of my BIOS file which contains the ME firmware? If yes, how can I modify this with the new image? With the FWUpdLCL I have no choice of which area I flash or yes? Hope to hear from you,

Regards hanson

Would you post a link to your BIOS please.

Hi there,

here's the requestet link: http://www.asrock.com/mb/Intel/X79%20Ext...ownload&os=BIOS

I use the version 2.80

Okay, the ME firmware is backed up in the BIOS region, GUID B3160739-1365-48A7-AECB-038652E2B528

Maybe if you replace this one with the updated one it will work, idk. Not normally something I have to deal with.

Beware, you may have to chop it and just add the update part of the ME firmware, not the whole ME.

For instance IIRC if you backup the ME Firmware with FWUpdLCL you might find the file just contains the upadate, the file is smaller than the whole 1.5MB SKU

Thank you very much, I found the entry. Do you know which tool to use for? MM Tool says invalid ffs file when I try to replace it. Also renaming the .bin to .ffs had no success. Should I use a hex editor?

Many thanks hanson

As posted above, I would be very wary of replacing the whole part of the GUID. Try updating with FWUpdLCL and before rebooting back it up with FWUpdLCL. If you used the full 1.5MB SKU for updating you might find it only uses a part of that image for updating which should be apparent by the size of the backup and the size of the 1.5MB SKU. Or you can skip the update and just do the backup to check.

I'll try to make a better explanation later in half an hour or so.

The ME Firmware contains data for your computer such as clock setups. Looking at the 1.5MB SKU 8.1.51.1471 linked on this board and your existing ME Firmware they are incompatible. Using the whole image would very likely leave your board bricked. Using it with FWUpdLCL is okay as this just takes the section from the 1.5MB SKU that is needed and leaves the ME Firmware settings such as clocks alone.

For you to update the GUID in the file you need to keep the ME Firmware settings in the first part of the image and only update the section after that.

If you look at the 1.5MB SKU 8.1.51.1471 in a hex editor you need to remove the section from 0x0 to 0x4cfff and replace it with the section from your BIOS (not including the EFI header).

Thanks a lot, I'll try that. Luckily I have a spare BIOS chip ASRock sent me recently. If something goes wrong I should be on the safe side.

Here is an example you can check against, untested. I don't know if it is also necessary to update the ME Firmware section if you are using an AsR flasher but the BIOS side is updated.

File deleted.

Hey CPOL,

thanks so far for your work. Unfortunately I had no success. I flashed your modified BIOS without problems. After that I updated ME FW by using FWUpdLCL. After the reboot my board tried to restore the original firmware. But maybe due to the changes you made it rebootet again and again and again, always updating the ME FW after restart. I interupted this loop finally and restored original settings by booting with my second chip, then changing the chip during running system and flashing back the original BIOS.

Regards hanson

Thanks for the report Hanson, sorry it didn't work but glad you recovered okay.

If after flashing the BIOS it did not try to reflash the ME Firmware then it is not using the backup as a reference but hard coded somewhere else as to what ME firmware should be installed. My guess would be after running the update it has tried to recover using the backup but as the backup also contains the newer version it fails the check on reboot so gets stuck in a loop of restoring the backup because it does not match the hard coded version number somewhere else in the BIOS.

It's also been a while since I've done these. Might need to do it the harder way of rebuilding the ME to the same settings as your board before replacing the backup ME firmware.
