Flash image for the HP ProBook 450 on Wistron board 12238-1, read from an MX25L6406E chip, a Macronix 64 Mbit (8 MB) SPI flash. Knowing the exact part helps choose the correct device profile in programmer software and confirms capacity before writing. Wistron numbers boards in the 12238-1 style for its HP designs. Use it to recover a unit with corrupted firmware or no boot, but save the original contents first and check the board number on the PCB matches before programming.
