BIOS image for the Wistron LZ57 project, board 10290-2 with PCB part 48.4PA01.021, marked as a UMA version reported working, in a 2.38 MB ZIP. UMA means integrated graphics only, so it should not be used on a board with a discrete GPU. Flash it to the SPI chip with a hardware programmer to recover a board with corrupted firmware. Save the original dump beforehand, verify the image size matches the chip, and confirm the board number and graphics configuration on your PCB.
