BIOS image for the ASUS X550VX laptop, mainboard revision 2, which the name identifies as an 8 MB flash dump, inside a 7.60 MB RAR. The image is intended for writing to the SPI chip with an external programmer when the laptop does not boot or the firmware is corrupted. ASUS boards store serial and LAN data in the BIOS region, so read and keep the original dump first. Check that the board revision is 2 and that your chip is 8 MB before writing.
