RePete222 Posted January 13, 2022 Share Posted January 13, 2022 (edited) I am attempting to installl Big Sur on my AMD hack (see sig), using OpenCore 0.7.6 as bootloader. After following the Dortania guide, I get this screenful of messages, ending with "OC: Watchdog status is 0". It gets stuck there, and does not bring up the picker screen. I have tried setting NVRAM WriteFlash and LegacyEnable to NO, and still get the same result. I also notice the message "OCCPU: Failed to get FSBFrequency data using Apple Platform Info - Not Found". Is this relevant to the issue? Thanks EDIT: Added boot logfile from latest attempt. Tried with CSM turned off in BIOS, got same result. config.plist opencore-2022-01-14-145601.txt Edited January 17, 2022 by RePete222 Mark solved Link to comment https://www.insanelymac.com/forum/topic/350398-solved-stuck-at-oc-watchdog-status-is-0-with-opencore-076/ Share on other sites More sharing options...
Allan Posted January 14, 2022 Share Posted January 14, 2022 Test his EFI folder please: https://tinyurl.com/3tpkbpmk You can perform a safe test by using a USB stick. 😉 Link to comment https://www.insanelymac.com/forum/topic/350398-solved-stuck-at-oc-watchdog-status-is-0-with-opencore-076/#findComment-2775124 Share on other sites More sharing options...
RePete222 Posted January 14, 2022 Author Share Posted January 14, 2022 That's worse! When I boot with that folder, it gets stuck on a blank screen, with nothing but an underscore cursor. Does not appear to have generated a logfile either.

Avery B Posted January 14, 2022 Share Posted January 14, 2022 Assuming your using the EFI from the first post. The FX 8350 does not have the RDRAND instruction, so I believe when OC tries to load HfsPlus, the driver crashes when trying to use that instruction. You will want to grab HFSPlusLegacy from here: https://github.com/acidanthera/OcBinaryData/blob/master/Drivers/HfsPlusLegacy.efi Don't forget to update your config.plist under UEFI->Drivers as well.

RePete222 Posted January 14, 2022 Author Share Posted January 14, 2022 Making some progress now! Made it to the picker screen. The first time, I barely had time to read it when some default selection was made. Would this be some old Clover or Chameleon setting hanging around & getting in the way? What do I need to change in config.plist to either lengthen or eliminate the timeout interval? Anyway, I did eventually manage to choose the Big Sur installer, and got it started loading. However, still not making it all the way into the installer--it hangs after writing the message "validate_root_image: validating root dmg /BaseSystem/BaseSystem.dmg" (was stuck there for over 5 minutes before I broke it off). I did not see a Reset NVRAM option on the picker menu. Since I am in the process of making the switch from Clover, I would like to be able to reset my NVRAM. Any config.plist setting needed to present that option? Attaching log from latest attempt. opencore-2022-01-14-202629.txt Link to comment https://www.insanelymac.com/forum/topic/350398-solved-stuck-at-oc-watchdog-status-is-0-with-opencore-076/#findComment-2775134 Share on other sites More sharing options...
RePete222 Posted January 17, 2022 Author Share Posted January 17, 2022 Success at last! Booted all the way into the Big Sur installer, which is chugging along as I write this. Apparently it takes about 11 minutes to get past the validate_root_image message; when I gave it enough time, it was crashing on a KP at first. After trying various things, I finally determined that I had only edited the Monterey-specific cpu_cores_per_pkg patch--I had missed the other two patches, including the one pertaining to Big Sur. Once those were taken care of, I got past the KP and made it all the way in.
