BIOS firmware package for the ASUS X450EP notebook, with the name indicating an X450EA-family image at version 1304. The ZIP is 1.74 MB compressed, so open it and check the actual image size against the SPI flash chip before writing anything. Technicians use such files to recover a board that fails to POST after a corrupted update by reflashing the chip with a programmer such as a CH341A. Read and save the original chip contents first, since serial numbers, MAC address and licensing data are stored there.
