BIOS .bin 8.00 MB Shared

BIOS dump for the ASUS X555L, an 8.00 MB raw binary marked ok as a working image. The name gives no board revision or CPU variant, and the X555L family covers several board versions, so compare carefully with the PCB before use. The size matches a 64 Mbit SPI flash, which holds the BIOS and Intel ME regions for this platform. Write it with an external programmer after saving the original chip contents, which also preserves serial and MAC information.
