Lenovo-branded BIOS image for the E11IS2 motherboard, packed as a 575 KB RAR archive. The file name gives no board revision, firmware version or flash chip details, so check the extracted image yourself. Dumps like this are written to the board's SPI flash with an external programmer to recover a corrupted or bricked firmware. Read and keep a backup of the existing chip before writing, confirm the PCB is marked E11IS2, and make sure the image size equals the chip capacity, or it will not fit or boot correctly.
