  8. 8. Typical parts of a motherboard. ABIT SE6
  9. 9. Cabling
  10. 10. For items in or attached to a system to work properly they must be securely connected. Be sure to carefully connect the cables.
  11. 11. Basic operations <ul><li>Power cord plugged in. (If plugged into a power strip, turn it on.
