Firmware image for the Toshiba M905 main board, tagged A1 Intel MV UMA, revision 2.2, as a .BIN file inside an 850 KB ZIP. UMA indicates the integrated-graphics build without a dedicated GPU, so it should not be used on discrete-graphics boards. Technicians write such dumps to the SPI BIOS chip with an external programmer to revive a board with corrupted firmware. Save the original contents before erasing, and verify that the revision and graphics variant match the board.
