BIOS image set for the Lenovo E40-70 built on Compal board LA-B091P, supplied as a 3.45 MB ZIP. Compal labels its boards with LA codes like this, printed on the PCB, and the exact code should match your unit before use. A dump of this kind restores a laptop with a damaged flash, a black screen or a failed update when written with a CH341A or similar programmer. Back up the existing chip contents first and confirm the file length matches the installed SPI chip.
