Sorry for the inconvenience friends.

I have this Chinese motherboard x79Dual cpu Jingsha .. But when trying to boot with my NVME SSD .. The bios menu recognizes my nvme 1tb but when I want to boot with it it does not appear in the list to choose it .. due to this problem does not start. I looked in aliexpress with a vendor for the updated bios , but I could not flash correctly because if fpt version 8.1 recognizes it to dunpe it but not to flash it, I mark error 7 .. a user told me that it is spi error .. Use fpt -i version 8.1 and mark that if you can .. For that reason I asked for help that I could do .. I saw a lot of information about incorporating an NVME module to boot into the bios .. but it requires a lot of experience and knowledge .. So I asked if you could help me modify said bios .. thanks

Very thanks
