Tested-OK BIOS firmware for the Lenovo Yoga 910-13IKB, based on the LCFC motherboard CYG50 NM-A901. The TESTED OK tag indicates the dump was confirmed working on real hardware by the person who saved it. NM-xxxx is the numbering used by LCFC, Lenovo's own ODM. Use it to reprogram the SPI flash with a programmer when the board is bricked or stuck after a failed update. Check the NM-A901 marking on the PCB, back up the original chip before writing, and make sure the image size matches the flash device capacity.
