BIOS image for the ASUS R417B, which uses the E402BP mainboard, revision 2.0, as stated in the name. Supplied as a 3.88 MB RAR, it serves to reprogram the SPI flash on a laptop that fails to start because of corrupted firmware. ASUS boards usually take such dumps via a CH341A-type programmer with a clip or after desoldering the chip. Save the existing chip contents first, confirm that E402BP and Rev 2.0 are printed on the PCB, and make sure the image size matches the flash capacity.
