ASUS K54L firmware file, 4 MB in size and without an extension. The name only states the model, with no version or revision. The size points to a 32 Mbit SPI chip, which can be rewritten using a CH341A or similar programmer, either in-circuit with a clip or off the board. Technicians apply such an image when the laptop powers up without display because of damaged firmware. Back up the original chip before erasing, and confirm that your board version is the same as the one this image came from.
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 @biosfilebins. 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 →
