That was pretty easy, thanks.Ensure you swap bootloaders first before changing your system.
It doesn't return the expected variable and there's no instructions for what to do when it doesn't include the expected variable, so I'm not sure what to do. I keep ending up at the same few pages when I search. While I've learned a lot, I don't see an obvious solution. Any suggestions?Inside EFI/OC/Tools/ you'll find drivers modGrubShell and VerifyMsrE2. If you followed the BIOS settings you should have enabled legacy option roms already. I've added these to OpenCore and these tools should be bootable from OpenCore's boot picker.
- At the OpenCore picker, choose modGrubShell
- If you only enter "setup_var 0x4ed" it will return it's current value which would be 0x01. 0=false/disable, 1=true/enable
- I recommend always check the current setting before changing and verify what you're checking. It helps with alleviating user error.
- If it returned expected variable and setting, press the up arrow which will populate the last command and then add the remaining. You should be entering "setup_var 0x04ed 0x01" to disable CFG Lock.
maybe type it in correctly?That was pretty easy, thanks.
I did two things that might be important for my problem below: I was more cautious and installed OC on my backup SSD. It worked for Catalina and I was able to update it to Monterey and boot it several times.
I also figured "If not now, when?" and updated to OC 0.8.0. Was that a mistake?
I have copied that functional EFI to my internal SSD and am booting Catalina from it with no obvious issues. I am, however, stuck at this point in your guide. I'd like to solve it before committing to Monterey on my internal SSD:

i have just seen your other posts, best to be using the same bios version from post 1 if you are following that section of the guide as using a later one may have a different set var variables and could ruin your bios if not done correctlyOK, please tell me what appears to be incorrect to you! They appear correct to me, and I have typed both commands multiple times.
3.) Newer BIOS only has the effect of disabling undervolting (not required) and a reset of the UEFI variables. You'll find OpenCore has several differences over Clover. You'll want to check your MSR lock, etc. or enable the appropriate quirks. But you give you an easy answer, you should not need to roll back BIOS. I simply keep mine on a lower revision to allow for undervolting. I'm not sure if a rollback is possible - I haven't had to attempt it.
