Main BIOS image for Lenovo board NM-A481 revision 1.0, an 8.00 MB binary. The NM-xxxx codes follow the LCFC numbering used by Lenovo's own ODM, and the code is printed on the PCB, so confirm both number and revision before flashing. The 8 MB size suits a 64 Mbit SPI chip, and the main label suggests it is the system flash rather than an EC file. Write it with an SPI programmer, but dump the original chip first to keep serial and licence data.
