A BIOS image for a Dell Inspiron 14z, with no exact model number, version or board number in the name. The 14z name covered more than one generation, so check the board carefully before using it. The 8 MB size corresponds to a 64 Mbit SPI flash. Technicians program such dumps with an external tool to repair boards that have no POST because of corrupted firmware. Read and keep the factory contents first, and confirm that the chip capacity matches.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosfilebins. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
