Intel DG43NB motherboard BIOS, a 4.00 MB binary image matching a 32 Mbit SPI flash chip. The board uses the G43 chipset with integrated graphics for LGA775 processors. Technicians write this full dump with an external programmer when the board stops booting after a failed update. Before flashing, confirm that the PCB carries the DG43NB marking, read and save the existing chip contents, which hold the unique MAC address, and check the programmer detects the chip size correctly.
