Patched SMBIOS but nothing has changed about negativespoofer HOT 8 CLOSED

When it finds the SMBIOS table it should work correctly.

I even try to get out of EFI-Shell and boot the os.

Not sure what you mean by that, but are you directly calling Windows bootx64.efi file like in this video?

Yes, I tried it that way.

This is exactly what I was trying to try

Try typing exit and if your OS starts booting without the PC doing a full reboot, you should be fine.

and I tried many more methods on BIOS, but nothing changed

Since my UEFI version is old, I tried it on a friend who has a new UEFI version. Nothing changed again. SMBIOS is still the same

Here is another method I tried

The address seem to be off (should be above 0xf0000 as far as I know). I think it's fall-backing to this function which I got working just half of the time (since both VM and real hardware that I have were able to find SMBIOS entry by the other two) and that does not seem to be reliable in the implementation it has.

Can you try to modify the FindEntry() function to look something like this so we know what method does it use to get the SMBIOS entry point?

SMBIOS_STRUCTURE_TABLE* FindEntry() 
{
    SMBIOS_STRUCTURE_TABLE* address = FindBySignature();
    if (address) 
    {
        Print(L"[INFO] Address found by signanture\n");
        return address;    
    }        

    address = FindByConfig();
    if (address) 
    {
        Print(L"[INFO] Address found by config\n");
        return address;
    }       

    address = FindByHob();
    if (address) 
    {
        Print(L"[INFO] Address found by hob\n");
        return address;
    }

    return 0;
}

I am attaching compiled version just in case you would have issues compiling it.

That is weird. Probably the next step would be to try to print the SMBIOS strings to see if it's really the table. If it is and it's still not working than it would probably need to copy the table to own allocated memory and rewrite the pointer to the table type.

I can't build as EFI, would you build that for print the SMBIOS strings?

I guess it will only work on certain baseboards. Thanks for the help.
