Working BIOS dump for mainboard NB2686_MB_V5, described as fully verified, in a RAR archive of about 6.3 MB. The name gives no device model, only the board number and V5 revision, which differs from the V3 boards with separate files. Use it to reflash the SPI chip with a programmer when the unit does not boot. Confirm V5 is printed on the PCB, read and keep the existing firmware, and check the image size equals the flash chip size.
