1033 2. Shell - The boot option points to internal flash shell.
1034 Bds will try to automatically create this type boot option when enumerate.
1035 3. Removable BlockIo - The boot option only points to the removable media
1036 device, like USB flash disk, DVD, Floppy etc.
1037 These device should contain a *removable* blockIo
1038 protocol in their device handle.
1039 Bds will try to automatically create this type boot option
1040 when enumerate.
1041 4. Fixed BlockIo - The boot option only points to a Fixed blockIo device,
1042 like HardDisk.
1043 These device should contain a *fixed* blockIo
1044 protocol in their device handle.
1045 BDS will skip fixed blockIo devices, and NOT
1046 automatically create boot option for them. But BDS
1047 will help to delete those fixed blockIo boot option,
1048 whose description rule conflict with other auto-created
1049 boot options.
1050 5. Non-BlockIo Simplefile - The boot option points to a device whose handle
1051 has SimpleFileSystem Protocol, but has no blockio
1052 protocol. These devices do not offer blockIo
1053 protocol, but BDS still can get the
1054 \EFI\BOOT\boot{machinename}.EFI by SimpleFileSystem
1055 Protocol.
1056 6. File - The boot option points to a file. These boot options are usually
1057 created by user manually or OS loader. BDS will not delete or modify
1058 these boot options.
