BIOS and EC firmware set for the Lenovo E10-30 netbook, board BM5387 revision 1.2, supplied as a 2.44 MB RAR. Having both the system BIOS and the embedded controller image is useful because many no-power or charging faults on such boards stem from a corrupt EC chip. Technicians write these images with an SPI programmer after reading and saving the original contents. Confirm the board label reads BM5387 rev 1.2 and check each image size against its target chip before flashing anything.
