A 4 MB BIOS image for the ASUS K54C laptop mainboard at revision 2.1. Matching the revision matters, as ASUS often ships several revisions of one model board with different firmware. This dump can be written to the SPI flash with an external programmer to repair a board that powers up without display. Read the original chip first and keep that backup, and confirm that the chip is 4 MB and that the label on the PCB reads REV 2.1.
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.
