Small backup for Lenovo board NM-C431, revision 1, tied in the name to the Type-C circuit and taken from a working laptop. At only 9.02 KB it is far too small to be a main BIOS image. It is more likely a dump of a small chip such as the USB Type-C or PD controller EEPROM, though the name does not confirm this. NM-xxxx numbers follow the LCFC pattern used on Lenovo mainboards. Identify the target chip and match its capacity before programming.
