BIOS archive for the ASUS X550CL notebook, matched to the X550CL mainboard at revision 2.1. ASUS boards carry the model name and revision silkscreened on the PCB, so verify that yours reads Rev 2.1 before using it. The 3.60 MB ZIP holds firmware for writing the SPI flash with an external programmer when the laptop will not power up or POST. Save the original chip contents first, since they include unique data such as serial and MAC, and confirm the image size matches the chip capacity.
