BIOS image for the Wistron board 07239-2, where the -2 suffix denotes the board revision. At 2.00 MB it corresponds to a 16 Mbit SPI flash chip, typical of older notebook platforms. The name gives no laptop model, firmware version or tested status. Use it to reprogram a corrupted BIOS chip with an external programmer after verifying the chip capacity and making a full read of the original. Revision matters with Wistron numbers, so make sure the PCB reads 07239-2 rather than another revision before writing.</p>
