Raw SPI read of a 256 Mbit flash, catalogued for a Lenovo laptop on LCFC board NM-C931, though the file name itself only gives the chip size and a reference C84019. The 32 MB BIN suits reprogramming with an external programmer to recover a board with corrupted firmware. LCFC is the Lenovo ODM using NM-xxxx codes. Confirm the board code printed on the PCB, keep a backup of the existing chip, and remember a unit-specific dump may carry serial data from its donor machine.
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 @dtechbios. Enginerys does not host this file.
