BIOS file for an ASUS U53F series laptop, 4 MB, using ASUS naming where the extension .211 is the BIOS version number; the brand is inferred from that convention rather than stated. ASUS capsule files of this kind are often meant for the built-in EZ Flash or WinFlash tools and may include a header that must be stripped before writing to the chip with a programmer. Check whether the image size matches the SPI flash, back up the original chip first, and confirm the board model and revision before flashing.
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 @bios_laptop. 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 →
