Lenovo BIOS archive for board IQ87SN revision 1.0, about 13.2 MB as a RAR file. The name does not give the PC model or firmware version, so open the archive and check the image size against the SPI flash on the board. Dumps like this are written with a hardware programmer to recover a desktop that will not post or that was bricked by a failed update. Read and back up the original chip, which may hold serial and system data, and verify the board marking and revision before writing.
