I've BigSur on an ssd on a pcie slot, and Monterey newly installed in another, I've installed Monterey after turning ON the VMM flag and SMBIOS spoofing OFF, but when it finished, and reset the two tweaks to default to get full acceleration as recommended by Marin Lo, Monterey can't boot, it shows me error on boot screen and reboot in loop. I've BigSur in another drive and it works well, no error, and If I turn ON again the VMM Flag and turn OFF the SMBIOS (like just before installing Monterey) it boot without problem, so how can I get Monterey working with VMM Flag OFF and SMBIOS ON ? because of these, my boot rom is still 144.0.0.0.0, thanks


Config: Opencore's Martin Lo V0.9.7, mac pro 5.1 dualcpu X5690, 96gb memory, RX5700XT, PixlasMode, BigSur on nvme ssd pcie slot.
