It works !
While Advance tab shows, but I am confused that many options under other tabs(eg: “Boot Conofiguration” under “Boot” tab) are still grey(unavailable).
Thanks !
BTW: Is that a problem that I should not switch GPU card anymore? I found this message on this post: [Request] Gigabyte AORUS 15G BIOS unlocked. seems that if I do so, there will be no output to display and need to use programmer to rescue the bios flash.
