Working BIOS for the Lenovo ThinkPad E14 Gen 2, board number NM-D011, marked as fully working. Comes in a 12.8 MB rar. NM-numbers follow the LCFC scheme, Lenovo's own ODM. Use it to reflash the SPI chip with a programmer when the laptop is bricked, loops on boot or will not display. ThinkPad flash often holds serial and system data, so read and save the original chip first. Confirm the board marking matches NM-D011 and that the image size corresponds to the flash capacity before writing it back.
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 @biosarchive. Enginerys does not host this file.
