For all who are not so patient I provide my debug-EFI. Who still has tips and optimizations, can share them with me, especially regarding USB-mapping. So, now have fun!Update 10.19.20: Everything works except Sleep.The PortMapping works.Best regards Fooose LAN-Fix-Realtek® 2.5GbE LAN : open Terminal: "sudo ifconfig en0 media 1000baseT mediaopt full-duplex"Thanks DSM2!I have taken these settings from this post: #1Bios: Version: F11b 10/19/2020 Major settings to be changed based on the default optimal settings: deactivate I2C and ESPI (essential to solve the random freeze problem) it must be in BIOS (advanced mode) under Settings -> AMD CBS -> FCH Common Options if applicable, set PCIe slot to Gen4 instead of Auto (may contribute to a better stability) enable X.M.P. memory profile disable trusted computing disable wake and boot over LAN enable power loading in Platform Power settings (may contribute to a better stability) setup fan profiles Other relevant default settings: Above 4G Decoding: disabled XHCI Hand-off: enabled HPET: enabled CSM support: enabled EFI_OC_0.6.4_B550AorusPro.zip

ah ok , proverò e ti faccio sapere , di nuovo tante grazie.

@Lorys89 e @dreamwhite gentilissimi per il vostro aiuto. Dopo qualche settimana di uso ho deciso di tornare indietro a Big Sur perchè le prestazioni sono calate abbastanza con Monterey. Vi ringrazio per la disponibilità e l'aiuto datomi. Rimontando la vecchia EFI che avevo fatto in Big Sur funziona tutto.

Anch’io preferisco Tuxera. 👍

Io li ho entrambi, e preferisco tuxera. Li comprai anni fa per mbp e imac originali

Let's try some other commands: sudo chmod -R 755 /Library/Extensions/ATTOExpressSASHBA.kext sudo chown -R root:wheel /Library/Extensions/ATTOExpressSASHBA.kext sudo spctl --master-disable sudo codesign --force --deep --sign - /Library/Extensions/ATTOCelerityFC.kext sudo codesign --force --deep --sign - /Library/Extensions/ATTOExpressPCI4.kext sudo codesign --force --deep --sign - /Library/Extensions/ATTOExpressSASHBA.kext sudo codesign --force --deep --sign - /Library/Extensions/ATTOExpressSASHBA2.kext sudo codesign --force --deep --sign - /Library/Extensions/ATTOExpressSASHBA3.kext sudo codesign --force --deep --sign - /Library/Extensions/ATTOExpressSASRAID.kext sudo codesign --force --deep --sign - /Library/Extensions/ATTOExpressSASRAID2.kext Disable sip booting in Recovery and typing into terminal: csrutil disable Reboot and try again! AMD works beautifully with ATTO cards

There's no direct connection but you need a suitable serial to make a lot of apple services work. You can use this tool: https://github.com/corpnewt/GenSMBIOS

Try even to re-install the official package from ATTO website, I attach it there ATTOExpressSASRAID2_3800f1.pkg.zip

You need the first two lines of code first, to repair owner and permissions, otherwise the kextload won't work

Try to issue these command in terminal: sudo chmod -R 755 /Library/Extensions/ATTOExpressSASRAID.kext sudo chown -R root:wheel /Library/Extensions/ATTOExpressSASRAID.kext sudo kextload /Library/Extensions/ATTOExpressSASRAID.kext Post the error messages if any

I do not think so it seems a permission problem and kext is not loaded at all

Do a kextstat command in terminal and post here the resulting listing, I suspect that it is blacklisted because of SIP and Gatekeeper

With which OSX do you see that raid disk? are you sure raid kext are loaded and are you sure Monterey does not block some of them? to check see in setting Software Extensions

have you checked if those kexts are loaded?
