    have to make backup 2 times of your chip and compare in Hxd hexeditor.

    youtube ch341a (if its 8 pin.. not sure if 16 can be done with ch341a) to see how it works.

    Add two more EB-8570p to the list of successfully broken BIOSes. I used a raspberry pi 3 b+ to flash. I like the Pomona 16 pin test clip, worked well for both the 8 and 16 pin SOIC.
    I wish I had the technical knowledge to have been able to figure this out on my own but alas I am not an experienced hardware technician.
    You rock Mazzif \\m//

    Updated my OP with some additional information about flashing.

    I'll discuss it here also.

    I did notice an issue when doing multiple like models. The MAC Address under the Intel Image>GbE Region and Intel Image>ME Region will obviously be identical as was captured in the original BIOS dump. Having multiple machines on the network with identical MAC caused me headaches. So far, editing the BIOS bin file prior to flashing to include unique MAC kills the NIC and makes it unavailable. My current workaround is to use the 'layouts' feature with flashrom and only write to the area contained in the VSS_store. This will leave everything in the Descriptor, GbE and ME regions intact.

    Also note: As far as I know, there is no way to retrieve the original MAC from the NIC once flashed. Using flashrom to read the MAC address from BIOS and write that to file before flashing is how I have been making sure I preserve the data. Of course none of this is needed when using layouts.

    Not even an issue, I have about 32 models mapped out in my layout file. Understand that I'm coming at this problem from handling a large volume of machines perspective. In a 'one off' type scenario, I doubt it would ever be a problem. But I did want to present the issue with the MAC in case that was important to someone.

    What is really sad (TBH) is the years worth of work and information I put out to help the community... And even though I have given the solution, people want to make their first post a complaint instead of a thanks. But that's just my opinion.

    If you have a working smc you should be good to go. I can't make smc files. What more do you need?

    How much more of a reply do I need to make? I do 8770W models (among others) all the time using the same exact techniques laid out in this thread.

    The answer is the same...Can we do it? Yes. How? Read post 1.

    nobody is making SMC bin files.. where did u see this lie ?

    what we do say is to get a programmer and read chip then we can change the BIOS BACKUP.BIN
