Hi,
There is no naming for bios flash back for x299 tuf mark 2 to rename the .cap file to and thus can not roll back bios
My prime deluxe has a posted message to rename for bios flash back and worked well
Not what for mark 2 no message on bios list I believe it was added to bios version 1503 for prime deluxe which I no longer have.
