BIOS image set for the Samsung NP-RV509 with motherboard part number BA92-07406A, board project scala2_ext, in a 1.61 MB RAR. BA92 codes are Samsung's own part numbers for main boards, handy for matching against the sticker on the PCB. The dump serves to reprogram the SPI flash chip externally when the laptop no longer boots. Match the part number and board name before writing, back up the existing firmware, and make sure the image size corresponds to the chip fitted.
