RAR archive of about 1.5 MB labelled AH530, which likely refers to the Fujitsu Lifebook AH530 notebook, although the name itself gives no brand, board number or firmware version. Unpack it with WinRAR or 7-Zip and examine the contents before use. Firmware of this type is written to the BIOS flash chip with a programmer to restore laptops that fail to boot. Confirm the board identity, check that the image length matches the chip capacity, and save the existing contents first.
