  1. Download was complete and successful
  2. Checksum matches that provided by the download site
  3. Software/driver is installed/loaded
  4. Software/driver recognizes existence of device(s)
  5. User has authority/access to perform action(s)
  6. Internal device settings/BIOS optimal for situation
