 | |
|   This function will enumerate all possible boot devices in the system, and
 | |
|   automatically create boot options for Network, Shell, Removable BlockIo, 
 | |
|   and Non-BlockIo Simplefile devices. 
 | |
|   
 | |
|   BDS separates EFI boot options into six types:
 | |
|   1. Network - The boot option points to the SimpleNetworkProtocol device. 
 | |
|                Bds will try to automatically create this type of boot option during enumeration.
 | |
|   2. Shell   - The boot option points to internal flash shell. 
 | |
|                Bds will try to automatically create this type of boot option during enumeration.
 | |
|   3. Removable BlockIo      - The boot option points to a removable media
 | |
|                               device, such as a USB flash drive or DVD drive.
 | |
|                               These devices should contain a *removable* blockIo
 | |
|                               protocol in their device handle.
 | |
|                               Bds will try to automatically create this type boot option 
 | |
|                               when enumerate.
 | |
|   4. Fixed BlockIo          - The boot option points to a Fixed blockIo device, 
 | |
|                               such as a hard disk.
 | |
|                               These devices should contain a *fixed* blockIo
 | |
|                               protocol in their device handle.
 | |
|                               BDS will skip fixed blockIo devices, and not
 | |
|                               automatically create boot option for them. But BDS 
 | |
|                               will help to delete those fixed blockIo boot options, 
 | |
|                               whose description rules conflict with other auto-created
 | |
|                               boot options.
 | |
|   5. Non-BlockIo Simplefile - The boot option points to a device whose handle 
 | |
|                               has SimpleFileSystem Protocol, but has no blockio
 | |
|                               protocol. These devices do not offer blockIo
 | |
|                               protocol, but BDS still can get the 
 | |
|                               \EFI\BOOT\boot{machinename}.EFI by SimpleFileSystem
 | |
|                               Protocol.
 | |
|   6. File    - The boot option points to a file. These boot options are usually 
 | |
|                created by the user, either manually or with an OS loader. BDS will not delete or modify
 | |
|                these boot options.
