BIOS archive for the Lenovo B50-30 on the LA-B102P motherboard, 2.53 MB as a zip. No revision, version or chip details appear in the name. The LA-xxxxP format is Compal's board-numbering pattern, so Compal is the ODM behind this design. The same board number is also listed for the B40-30 elsewhere, so confirm the model before use. Program the image into the SPI flash with a hardware programmer after backing up the original, and verify the file size equals the chip capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @bios_laptop. Enginerys does not host this file.
