ASUS BIOS image, 8 MB raw binary, named for the A550CC and X550CC notebooks, which share a platform under different regional model names. The size corresponds to a 64 Mbit SPI flash chip. Repair shops use such an image to revive a dead or boot-looping board by flashing it with an external programmer after desoldering or clipping onto the chip. No board revision is given in the name, so compare the mainboard revision printed on the PCB, save the original contents first, and expect serial and system data to need restoring afterwards.
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.
