how to disable cfg-lock in bios？

xiecang commented 1 year ago

Yes, it is necessary to disable cfg-lock.

I'll cut a picture after work.

I was under the impression that the path was "startup -> Bios Write Protection", but I'm not very sure.

This doesn't seem to be CFG lock. I followed the methods online and tried modifying the CFG lock address in UEFI, but I received a UEFI write protection prompt. I guess it's not possible, and I'm not sure how much it would affect performance without this.

CFG-Lock is a setting in your BIOS that allows for a specific register(in this case the MSR 0xE2) to be written to.

On my motherboard, the "BIOS Flash Protection" setting is described as "Enable Flash Protection Range Registers", and disabling this option does work for me.

If that doesn't solve your problem, try enabling Kenel Quicks "AppleCpuPmCfgLock", "AppleXcpmCfgLock" in config.plist.
