RAR archive with BIOS firmware for the Dell N4030. The name also carries 48.4EK01.021, a Compal-style board identifier that ties the dump to a specific motherboard and revision. The archive is 1.87 MB and must be unpacked before flashing. Compare the number printed on the PCB with this identifier before relying on it. Use an SPI programmer to read and back up the existing chip, then write and verify the extracted image, checking that its size fits the chip.
