Dell Latitude D620 BIOS image for a board variant marked QD with NVS 110M graphics, followed by N-A3 in the name, which likely refers to revision or build details not explained further. The 1 MB binary fits an 8 Mbit SPI flash and is meant for reprogramming with an external programmer when the laptop shows no POST or a corrupted BIOS.
