MMTOOL APTIO TUTORIAL MOD
Windows Mod to remove auto update microcode on boot:
MMTOOL APTIO TUTORIAL PATCH
Go back to Information screen, in my case Current Firmware ID: 0ABUC000 7, ROM file ID: 0ABUC000 so on the setup tab i had to check " Do not Check ROM ID" then click Flash ONLY if you take the risk like me.Be sure to choose Datatype:Hex-values then hit searchħ) Press F3 to find again till you reach this pattern(highlighted):Ĩ) (1) Indicates the microcode version, 17 in this case, we want 00 (cpu stock), (2) the platform ID (the search context we reached at) (3) the microcode length = 5000 (in my case) in reverse (important to know when the microcode ends in order to remove).ĩ) Adjust the cursor on the beginning of the highlight text/microcode (01) right click>Select Block>Length>5000 or whatever in your caseġ0) Delete the highlighted blocks (after step 9) then save the fileġ1) Do the same with the second result from step 3 to 10 then saveġ2) go back to UEFITool, double click the first result like you did in step 4, right click the highlighted structure in the main dialogue > Replace as-is then choose the FIRSTfile you edited in HxDġ3) Double click the third result and follow step 12 with the SECOND file you edited in HxDġ4) You will see "Rebuild" in action row, File>Save image as> P15SM04.PM2 in my case (can be any name as long as your flashing tool recognize it)ġ5) Open AMI Aptio MMTool > Load Image > your modified rom > CPU Patch Tab and verify there is no 06C3 in CPU ID rom file.- And now you can flash this bios file with AFUWIN. Browse your edited fss file and click ok then File->Save image file. Back to UEFITool right click on your GUID and press replace as is. Double check the saved file size an continue only if its exactly 2 621 440 bytes Search for 01 01 00 01 01 01 and make sure you have only one matches (you should have only one) and change the red value to 01 and save the file. The reason is because default if you go to your bios you see these tabs: (Main: enabled, Advanced: enabled, Chipset: disabled, Boot: enabled, Security: enabled, Save & Exit: enabled). They store in an boolean array the hidden/showable tabs in our case it is: 01 01 00 01 01 01 On the messages block double click on the found entry and right click on it => extract as is and save the fss file, don't close UEFI Tool. Click File->Search->GUID and type in your GUID (899407D7-99.), select header only then click search. Open UEFITool (0.21.4_win) and open your rom file. I coudn't manage to replace this module with MMTool so we just need the GUID for the Setup module (899407D7-99FE-43D8-9A21-79EC328CAC21 for me) Load the image and find the FileName: Setup row: Now we have to use MMTool (mmtool_aptio_4.50.0.23) to gather some information. You don't have to set all these menus to USER here so just leave everything untoched here. The chipset tab is where the really deep things happen (Memory frequency, PCI-E configurations, IGP configurations, LCD setting, TOLUD config (default is dynamic) etc.). You can force these menupoints to show up by changing the access to USER like on the picture Go to Advanced in the left tree and you will see your advanced menupoints in your bios something like this, except you will see Default instead of USER in the Access/Use column. Save your current rom file with AFUWINGUI v5.05.04., backup a lot of copies of this somewhere safe. I made this tutorial with the newest 209 bios already flashed, so maybe you want it too. I do not recommend to do this, its just a part of my eGPU project. I managed to successfully unlock my iron's hidden bios features so i just show you guys the steps i made.
