Samsung NP900X4D firmware supplied as a 2.49 MB RAR, with the name stating only the model and no board number, project name or revision. For repair, the image is used to rewrite the BIOS flash on a unit that is bricked or will not start after an update. Because the 900X series includes several board versions, compare the codes printed on the PCB before relying on this file. Back up the original chip with an SPI programmer, since it may hold serial and licence data, and confirm the image fits the chip size.
