Hi Friend,
Acer haven't WiFi or other Whitelist into, only limits present are on Card FW where manuufacturer can get it inside, the Menu Tabs are all Unlocked so 7Tabs with Power and Advanced unhidden.

0985                cmp    [rdi+rcx], rax
0989                jz      short loc_1800009E4
098B                mov    rax, [rcx+50h]
098F                cmp    [rdi+rcx], rax
0993                jz      short loc_1800009E4

Theseare the modifies :

0989 : 74 59  to  74 00    jz      short loc_1800009E4  to  jz $+2
0993 : 74 4F  to  74 00    jz      short loc_1800009E4  to  jz $+2

If do You want learn as to do modifies, I can show the way !
Let me know, and post some screen shots to show Menu Tabs Unlocked and can see if there are some EFI code to unlock for more otions.
If You have problem to reflash, there is another way to do, so ask to me !

i want to learn how to unlock the acer E1-471G bios v2.18 to 7 TAB'S menu
i try use InsydeH2OZEZ and InsydeH2OUVE ，But it didn't unlock it
i try the hex-rays‘s’ ida-free version to find which you said, also try to find the "74 59" and "74 4F" in hxd TOOL, i HAVE No progress at present
could you please help me how to unlock the “ advanced ”  and the “POWER” menu? thanks a lot

the file ZQS.FD is original V1.29
the file ZQS_S.FD is original V2.18

about “_S” ： The high version is signed, the low version is not signed, please help to unlock these two files

I am  not clear if unlocking will cause additional changes to the file in key areas, so In case I fail to learn, I will use your unlocked BIOS to update the CPU microcode and then upgrade my i5-2450M to i7-3632QM
