BIOS for the Dell Latitude 3300 built on board 17910-1, a number that follows the Wistron format for Dell notebooks. The RAR is about 11.4 MB. Reflash the SPI chip with an external programmer when the laptop has no display, a power LED code, or a damaged BIOS after an update. Dell boards keep the service tag and other system data in flash, so read and save the original chip before writing. Confirm the board number on the PCB and check the image fits the chip.
