BIOS firmware for the Lenovo Yoga 11e, based on board 17833-1M, archived as a 4.06 MB rar. The 17833-1M number follows Wistron's numbering scheme, the ODM that built this education-oriented convertible for Lenovo. Technicians use such a dump to reflash the SPI chip with a programmer to revive a unit stuck at a black screen or locked by corrupted firmware. Compare the board number on the PCB, read and save the existing chip contents first, and check that the image size suits the flash chip before writing.
