BIOS archive for the Asus S551LB laptop, mainboard revision 2.2, containing a file named for the S551LBF model with 1212 likely indicating its version. Packed as a 3.27 MB ZIP, it can be used to repair a corrupted firmware by programming the SPI flash with an external programmer, or as a reference image for comparison. Confirm the PCB is revision 2.2, since images from other revisions may not boot. Read and store the original chip before writing, and check that the image size matches the installed flash.
