BIOS together with EC firmware for the ASUS P2451FB laptop, board revision 2.0, with the system image matching a 16MB flash chip. Having the embedded controller code in the same package helps when the keyboard, battery charging or power button behaviour is faulty. Program the SPI chip with a hardware programmer such as a CH341A, and dump the original contents before erasing anything. Make sure the PCB carries the same revision, and check the EC chip type before flashing its file separately.
