Raw 8 MB BIOS image for an X415MA board, carrying firmware version 302 as shown by the .302 suffix. The name follows ASUS naming for capsule files, though no brand is stated, so confirm the model on the board label. Being a plain .bin file of 8 MB, it matches the size of an 8 MB SPI flash and can be written with a programmer such as a CH341A. Check whether it is a full dump or an update capsule with a header, since capsules may need trimming, and back up the original chip before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @bioshub. Enginerys does not host this file.
How to open a .bin file
A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
