Large archive of 912 MB carrying the Lubuntu 16.04.6 desktop release for 64-bit PCs, a lightweight Linux distribution, although the catalogue lists it as firmware. It is not a BIOS image; it is an installation or live system image. Technicians often write such an image to a USB stick to boot a machine for hardware tests, or to run flashing and dump tools under Linux. Extract the RAR, write the ISO with a tool such as Rufus or Etcher, and check the checksum if one is provided.
