Firmware archive for the Panasonic Toughbook CF-33, board code DHLB1170ZF-X1 as shown in the name, apparently a second copy of this upload. Panasonic's assembly codes are printed on the motherboard, so confirm the match before using the dump. A full image like this serves to reprogram the SPI BIOS chip with an external programmer when the tablet fails to start or the firmware is damaged. Back up the existing chip first, and check that the image size corresponds to the flash capacity.
