BIOS image for a Lenovo laptop motherboard numbered NM-A273, which follows the LCFC numbering used by Lenovo's own ODM. The 8.00 MB binary fits a 64 Mbit SPI flash chip and gives no revision or model name. Use it with a hardware programmer to restore a board with corrupted or missing firmware. Check the board number and revision silkscreened on the PCB before writing. Read and keep a copy of the original chip, since it may hold serial-number and licensing data that a donor image would replace.
