I just did a test and grabbed the Vaughn Rom from the G4 Bios update and changed the connector information to match my 4170, fixed the checksum, added GOP, and the card posted, and all outputs worked, everything worked (except Catalina!) albeit with a much decreased performance (a bit less than 1/3) in Valley. (and less ram)

So I guess the Roms are "compatible" but it depends if it's Pegatron or Vaughn, it may be different on your card, but it could be a problem with how you patched your connectors.

Hi, i have a problem, i am able to boot with clover and install Mojave on my HP ProBook 640 G2, and i leave it at that it works, minus sound, battery, etc, but when i do the guides post install instructions and restart, the first time i have sound, battery, keyboard shortcuts, etc, but if i restart again the boot gets stucked almost at the last step (Picture attached).

I was able to get the info for the reporting files on the first reboot (after post install instructions)

Thanks in advance for any help you could give me.

You have duplicate kexts.

Check /Library/Extensions on the system disk and /EFI/Clover/Kexts/Other on the EFI partition.

I have been using RehabMans method on my HP 440 G5 with no issues for the past 3 years, I haven't updated in a long time, currently on Clover with Catalina, but was looking at updating to BigSur. MasterAmp seems to have a good working method, so will hopefully copy yours.

Thanks for your response, but it didn't work, i deleted the duplicated kexts from /EFI/Cover/kexts/Other and i got stucked in the same place, it still says that kext are duplicated, what i found that sorta works is if i boot with the USB installer, and i rebuild the kext cache (sudo kextcache -i /), i can restart and boot normaly, but if i dont rebuild the cache i get stucked.

Any ideas?

Wrong choice. It would have been better to remove them from /Library/Extensions instead.

Thanks for the suggestion, it did the trick, now i only have to figure out how to get WiFi going, because my WiFi cards is an Intel Dual Band Wireless-AC 7265 and i think there is no diver for that, but thanks for the help.

I have been using clover and Catalina. I have just purchased another nvme drive, so I can keep the current install, in case it doesnt work out. I've been out the loop for a while now. Whats the best way to get to BigSur with a fresh install? Im looking at [Guide] Booting The USB Installer Using OpenCore, but this guide shows how to use recovery with Catalina. Is this the way to go then upgrade to BigSur?
Kind regards.
