No sorry not possible that kind of help my advice is to try with another disk if you can't define better if is a firmware related problem Your system should start easily as we did with @valmeidasome months ago so problems is elsewhere and I can't figure where by now sorry by the way..MMIO is important for post installation steps for a full functionality in installation steps you could also null all of the to zero have you 4g parameter in bios? ON/off

finish to try the others.. I have a big doubt also 🙂 your GPU has a UEFI bios? could you try to enable CSM in ASUS bios and see if it works in a different way? pS out of ideas

Archive.zip replace the config.plist and put ssdt you find in zip file inside ACPI folder (thanks @Gengik84to advice to try this)

config.plist 4.zip this is last thing to try by now..with opencore) I have no others ideas to try for now... sorry

usually in Windows with Samsung magician utility I do not know if it could help in the past there was a problem with some Samsung NVME firmware

ehm bios of your Samsung 970 is updated to work with OS X? I have also this doubt

ok try latest EFi I have put above change completely the previous one (backup it ) below two configs are for opencore EFI I have nulled AMD Power tools kext for now try with Opencore EFI config.plist 3.zip config.plist 2.zip

poco---molto poco 😛 😛

EFI.zip this is completely different approach Clover Bootloader is used..let see if we do some steps further

Big Sur release or beta?

MMIO are loaded fine try this if you want config.plist.zip

config.plist.zip could you try this? same EFI

puoi provare a cambiare questa patch nel config la n.21 mettere questo al posto di replace B9770200 00B80606 0606BA06 0606060F 300F09 e poi riavvii e vedi se fa ugulae @Sundraw prova tu senno' devo rimetterti tutti i seriali sul config 🙂

purtroppo a volte ( e non si capisce benissimo da cosa dipenda) con audio USB si puo' avere qualche problema da me non accade e sono fortunato in quanto la mia integrata e' una sorta di audio USB Potresti provare a cambiare l'ultima patch del kernel (fix pat) chiedi a @iCanaroe a @tomnicche nei loro sistemi AMD la devono usare come te..magari si risolve , a me non serve, e fortunatamente nel mio non ho problemi

@Cipollinaposta il tuo config senza seriali per dargli un'occhiata se non hai risolto

default one in my case...but this app is very interesting.. many AMD user like to use an Intel CPU power management like as real intel Mac.. I prefer AMD way 🙂

you say it shutdown..any debug or verbose lines? it turn off your pc or it reboots? it seems x299x bios are a bit crappy for mackintosh..but I can't say it no experience with it

config.plist.zip your bios settings seem to be good try only to enable ERP after first try of above config if it fails in this config I have added for you all MMIO resulting from your previous debug If you change some parameters on bios they could change and you have to recalculate them properly

Hi @jncasey maybe it is another parameter or mmio to find for you in my system I can boot all system with a minimal set of quirks important is to find right combination for own needs

@cleverhomewe can continue in this thread:

@cleverhomeHi try this and see if it does better things EFI_cleverhome.zip try with CSM Disabled in your Bios then if it starts or not post debug log thanks

shutdown or reboot? post screen capture of your bios settings

try to enable one on one the latest four..with some combinations it could start..all no

however seems weird that skipped because values are pretty the same if I see well

ok for each different one you have to convert it Fromm ex to decimal..and put in your config.plist mmio whithelist in this way
