    Automatically finding NVRAM/VSS store location

    I have an application which modifies only VSS store/NVRAM. Right now I have manually made a layout table for lots of different models but I would like to make it automated.


    UEFITool is able to find different regions. For example HP 840 G1 has NVRAM starting from DB0000h.


    I would like to know how does it locate it. Is it written somewhere in the beginning of bios file?

      LG 55LM6200-TA country group/Area option

      Youtube, Netflix and LG Smart store icons briefly appear in the apps list but then automatically disappear after doing 'Initialisation of Premium' via the standard menu, I'm guessing this is due to the Country/Area group its set to is wrong for the UK.

      Unable to change the country group, Area option can be changed which alters the country group but none make any difference. So believe its the country group that needs changing....

      Hi all. I'm Muerto, the creator of SMCTool/SMCFT. I thought this would be a good home for discussion regarding an open source pet project I've been working on that aims in easing Mac BIOS/UEFI analysis and editing. It is currently developed for Windows, however is Wine compatible based on my own testing, and feedback from others. Project available on Github, there is also a manual with basic usage instructions.



      In terms of editing, it can export and replace the Fsys Store, edit the serial number + hwc, clean NVRAM stores, export and replace the ME Region in a limited...
