Raw BIOS dump for a Lenovo board NM-A311 revision 1.0, platform codes ACLU9 and ACLU0, as a BIN file of 8.00 MB, which matches a 64 Mbit SPI flash chip. This LCFC board is used in Lenovo G40 and G50 series laptops, though the name does not say which model this dump came from. The NM-xxxx numbering belongs to LCFC, Lenovo's design arm. Write it with an SPI programmer when a board has corrupt firmware or no display. Save the original chip first, and confirm the chip capacity is 8 MB.
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 @bioshub. Enginerys does not host this file.
