Firmware for a board labelled NB2150_PCB_MB_V3, with an HF tag whose meaning the name does not explain, stated to be a 100 percent working BIOS. The RAR is 14.7 MB, larger than the i5-10210U variant, so it may include more than one file; check the contents before flashing. Use a programmer to write the correct image to the SPI chip after saving the original. Verify the NB2150 V3 marking on the PCB and confirm the dump size matches your flash chip, since a mismatched image will not fit.
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.
