Firmware archive for the Acer Aspire 4315, noted as the Celeron-equipped version. No board number appears in the name, so verify the motherboard markings yourself before using it. The RAR is small at 528 KB, consistent with older laptops using a 512 KB BIOS chip. Technicians flash such images with an external programmer to bring back boards that fail to start after corruption. Read and keep the original flash content first, and check that the extracted binary length exactly matches the capacity of the chip on the board.
