Lenovo Yoga 370 BIOS for the Compal LA-E291P board, described as fixing M.2 drive detection and as fully working. It is supplied in a 15.7 MB RAR. LA-xxxxP numbers follow the Compal board scheme, the ODM that built this notebook. Program the image into the SPI flash with a CH341A, RT809H or similar tool when an SSD is not recognized or the board is bricked. Keep a copy of the original dump and confirm the image size matches the chip.
