    Still struggling.Could i need an older bios.Is there a way of poss obtaining older bioses not published on main download page ie 1.01 ,1.02. I tried ftp put not there any more and download url string is not hackable i think.

    Does it need a specific bios as suggested on another post.

    Is there a way of obtaining crisis disk .

    Is there poss file on laptop's nvme that contain bios as i could mount in another computer.(unless its bitlocked.)

    thanks
