BIOS dump for the AIR-15 laptop built on the NB8606_MB_V4 mainboard, sized for a 16 MB flash chip and compressed into a 5.83 MB RAR archive. The name gives no brand or firmware version, so verify the board marking against V4 before use. Such an image is written directly to the SPI chip with a programmer like the CH341A when a unit will not post or the firmware is corrupted. Read and save the original chip contents first, and make sure the extracted file is exactly 16 MB so it fits the chip.
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.
