Hello, could you please tell me your bios version and ec version? I want to change the bios program to achieve the purpose of system installation.then you have no other option but to try with the older efi at my repo. It is set up for CFG LOCK. Try it and then tell me the problem with details.
i have exact same version but still cant get to advanced settings menu on bios..
are you sure you are not missing some small step? )
more then 4 hours of digging.. (tried fn + asdfgh then O then F10 etc.. and your suggestion.. still no luck..)
by the way, no cfg-lock version does not work on me also..
was dw1820a installed from beginning? or after you installed catalina and replaced the original wifi with dw1820a?
and one more thing..
which disk did you installed catalina? the one comes with laptop or the second you added?
i found the cfg-lock is at 0x3E in bios rom file (i extracted it ), and i will try setup_var3
by the way , i am using hackintosh computers more then 15 years i had many desktop and laptops. current desktop is z370 aorus 5 with rx580 , 32gb ram, 1tb nvme
on this laptop, the key combination you mentioned is not working for me..
1- the key combination does not work for me. so i used nocfg config of you. i used unibeast and installed 10.15.4, then replaced the EFI with yours.. when i boot with it, many messages appears (which i can not read, it is too fast), then laptop reboots suddenly.
when i only use your kexts and config.plist (replaced the files on original unibeast efi folder), still the same..
if i use https://github.com/marianopela/Lenovo-Ideapad-S540-14IML-Hackintosh EFI folder. it gets to setup screen. but when i try to format the disk with disk utility the laptop reboots suddenly (or if i want 1-2 minute).
marianopela have opencore efi folder but, it hangs after 7-8 lines of display.
