Lenovo Y700 BIOS dump for board NM-A541 revision 1.0, marked with the BY511 project name. NM-xxxx codes come from LCFC, Lenovo's own ODM, and the code appears on the PCB near the edge. The zip holds a bin file intended for external SPI programming to bring back a board with corrupt firmware. Read and save the original chip first, check that the board number and revision agree, and confirm that the capacity of the flash on your board matches the image, as a mismatched dump will not fit.
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 @vinafix_bios. Enginerys does not host this file.
