BIOS dump for a Dell Latitude D620, taken from an MX25L8005 flash chip and marked ok, meaning it was reported as working. The 1 MB size matches the 8 Mbit capacity of that Macronix part, so it can be written directly with a common SPI programmer to recover a board that is dead or stuck after a failed update. The file carries no extension; treat it as a raw binary. Read and keep the original chip contents first, and confirm the board variant matches before flashing.
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 @biosarchive. 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 →
