                     You can override the kernel ID in the selected image with the
                        Kernel ID drop-down list box. 
                
- 
                     You can override the RAM disk ID in the selected image with the
                        RAM disk ID (RAMFS) drop-down list box.

                     Click the Enable monitoring check box to specify that
                        detailed CloudWatch metric gathering should be enabled for your new
                        instance(s).

                     The Storage section will only display if you have an EBS-backed image. If
                        this is the case, you can configure additional storage for your
                        instance:
                    
                        - 
                             Select a volume type using the Volume
                                drop-down list box. 
                        
- 
                             Type the desired mapping for the storage into the
                                Mapping text box (for example:
                                    /dev/sdb).
                        
- 
                             If you want to create the storage from an existing snapshot,
                                specify it in the Snapshot drop-down list
                                box.
                        
- 
                             Type the size of the attached storage in gigabytes into the
                                Size (GB) text box. 
                        
- 
                             The DELETE ON TERMINATE indicator shows that the attached storage 
                                is to be automatically deleted by default when the instance is terminated. This option 
                            is non-editable.
                            Note: The DELETE ON TERMINATE indicator is not applicable 
                                for launch configurations.

                             Click the Add device button to add this storage.
                        
- 
                            You can delete storage you've already added by clicking the minus
                                button (⊝) on the right side of the storage list item.
