Binary BIOS dump for a Dell desktop board marked E93839, with GA0402 as an additional code from the name, compressed into a 2.26 MB ZIP. The raw BIN can be written straight to the SPI flash with a programmer such as a CH341A or RT809 when the system is bricked. Read and save the original chip first, since Dell keeps the service tag and system data in flash. Verify the extracted image size matches the chip and that the board marking is E93839.
