Firmware archive for a notebook identified as 15-e049sf, which is likely an HP model although the brand is not stated, on Quanta motherboard DA0R75MB6C0. Under the Quanta pattern, the ending characters give the revision. The 2.34 MB RAR file holds an image for direct SPI chip programming to recover from a corrupted BIOS. Confirm the board code printed on the PCB. Save the original chip contents first, since they carry the serial number and system identifiers.
