Original BIOS dump for a Lenovo laptop on LCFC board NM-B911, integrated graphics version with an Intel Core i5-8265U, S-spec SREJQ, in a 6.13 MB RAR. LCFC is the Lenovo-owned ODM using the NM-xxxx numbering. A full image like this is used to recover boards with corrupted firmware, written to the SPI chip via programmer. Make sure the board is the integrated graphics variant, save the original chip before writing, and confirm the size matches the flash chip; serial and key data may need restoring.
