Raw BIOS image named simply 1420, 4.00 MB in size. The name is minimal: it offers only this number, with no brand, board number, revision or version, so the target machine must be confirmed independently. Such binaries are written to the SPI flash chip with an external programmer to restore a board with corrupted firmware. Before any write, read and archive the original chip contents, check that the flash is a 4 MB part, and compare the board markings with the source of this dump.
