Firmware image for Inventec-numbered board 6050A2491301, revision A02. Unlike the others in the series, the name has no MB suffix, and it gives no device model. The RAR archive should contain a dump for the SPI flash, written with a hardware programmer to bring back a board with corrupted firmware. Make a copy of the original chip contents first and make sure the image size matches the chip capacity before you program it.
