BIOS archive labelled NBKB1415, version 1.0, packed as a 2.27 MB RAR. The name carries no laptop brand, model or chip details, only this code, which likely identifies the board or project. Before flashing, extract the image and compare its size with the capacity of the SPI flash on your board, because a mismatched image will not fit. Read and keep a copy of the original chip with a programmer first. A separate 4 MB EC variant with the same code also exists, so compare both before choosing one.
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.
