Flash dump for the Dell Precision M4700 mobile workstation, BIOS version A14, covering the chips labelled U52 and U53 on the board. The RAR is 5.89 MB and is expected to contain a separate image for each position. Identify both flash ICs on the board, read and keep the existing contents first, then write each file to its matching chip with an SPI programmer. Mixing up the two images, or writing a file that does not match the chip size, will leave the system unbootable.
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.
