Firmware archive for the ASUS PU551LA laptop, labelled revision 2.1, distributed as a 5.34 MB RAR. The revision in the name refers to the motherboard, so verify it against the marking on the PCB before use, because ASUS revisions of one model can need different images. Such files are used to rewrite the BIOS flash chip with a programmer when the laptop is dead, fails to POST or has corrupted firmware. Extract the image, confirm it fits the chip, and keep a backup of the original dump first.
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 @biosarchive. Enginerys does not host this file.
