hi,
i want to use hackintosh catalina on IdeaPad S540 14IWL
i used the tutorial at https://www.tonymacx86.com/threads/guide...gs.293504/
the author of the guide says to enter advanced bios, with the following key combination:
Power off the laptop. Power button to turn on → F2 to enter the normal BIOS → Power button to turn off → then press the following keys in sequence:
F1 → 1 → Q → A → Z
F2 → 2 → W → S → X
F3 → 3 → E → D → C
F4 → 4 → R → F → V
F5 → 5 → T → G → B
F6 → 6 → Y → H → N
Turn on the power button → F2 enters the hidden BIOS (if unsuccessful, please speed up your hand and try again). Then go to:
Advanced → Power & Performance → CPU-Power Management Control → CPU Lock Configuration → CFG Lock → Disabled
but it is not working on my laptop. i have version 30 bios (i tried with 27 and 28 also)
but still no luck..
so i got the bios updater and extracted the rom.
i have H2OEZE easy binary editor and export fd with this rom.
i have UEFI variable editor H2OUVE i can see the menu with loading fd file.
but i dont know how to enable the advanced tab.
if there is an option to modify the bios rom permenantly.. i need help..
by the way, i found the address of the CFG_LOCK at 0x3E and value was 0x03 with uefi viewer on macos (0xACE83 One Of: CFG Lock, VarStoreInfo (VarOffset/VarName): 0x3E, VarStore: 0x3, QuestionId: 0x16C, Size: 1, )
i changed it with setup_var on grub (setup_var_3 worked for me , i used setup_var_3 0x3E 0x00).. but it seems it was not working..
here are the rom, dumped fd file and the original bios installer

i extracted it from http://www.ogretbana.com/lenovo/ahcn30ww.exe
please help
