The file as downloaded from Asus is a compacted archive file. You have to unpack the actual BIOS ROM image file from that archive. The actual file you use for the update has a .CAP suffix.hello guys so i downloaded the bios version 5862 ( i currently have the version 5606) but i get this "selected file is not a proper BIOS" (all this in the ASUS PRIME A320M-K ) what shall i do?
The OP is trying to update the BIOS, not Windows.If Windows 10 is not updating, you can try to restart Windows Update services. The followings are the detailed operation methods. Step 1: Right-click the Start menu of Windows 10 or press Windows key + X key together, then choose Command Prompt(Admin) .
