BIOS file for the ASUS K53SM notebook, version 214 according to the name, stored as a 4 MB binary. That size matches a 32 Mbit SPI flash. Images like this can be programmed directly to the chip to recover a board that will not post, although some ASUS files carry a capsule header that must be removed first. Compare the image length with the chip capacity, dump and keep the original contents before erasing, and confirm the board is a K53SM rather than a similar K53 variant.
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 @biosbigarchives. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
