CAUTION:
To avoid the risk of damage to your system or expansion boards,
remove all AC power cords before installing or removing non-hot-plug
expansion boards. Moving the Power On/Standby button to the standby
position still provides auxiliary power to the PCI expansion slot and may
damage the board or other system components.

2.
Disconnect any external cables connected to expansion boards.
3.
