RAR archive with BIOS and EC firmware for the Lenovo E10-30, board BM5387 at revision 1.2, marked in the name as fully working. Having both images lets a technician restore a board whose system BIOS and embedded controller code are corrupted, which often shows as no power or no display. Write each file to its matching chip with an SPI programmer after confirming chip capacities agree with the image sizes. Back up the original contents first, and confirm the board number and revision on the PCB match 1.2.
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 @biosarchive. Enginerys does not host this file.
