hi @MaLd0n first thank you for helping me, but I have question .. yesterday I updated bios G1 sniper B7 from bios F5 to F22f (latest), so it is possible to put your DSDT (dump from F5) or I must dump again with came from F22f
note:
with F5 bios I can't get Big Sur installer running always get KP
with F22f bios version Big Sur Installer is running well
thank for your advance
