8d3b5aff | 137 | For EFI boot option, BDS separate them as six types:\r |
138 | 1. Network - The boot option points to the SimpleNetworkProtocol device. \r | |
139 | Bds will try to automatically create this type boot option when enumerate.\r | |
140 | 2. Shell - The boot option points to internal flash shell. \r | |
141 | Bds will try to automatically create this type boot option when enumerate.\r | |
142 | 3. Removable BlockIo - The boot option only points to the removable media\r | |
143 | device, like USB flash disk, DVD, Floppy etc.\r | |
144 | These device should contain a *removable* blockIo\r | |
145 | protocol in their device handle.\r | |
146 | Bds will try to automatically create this type boot option \r | |

148 | 4. Fixed BlockIo - The boot option only points to a Fixed blockIo device, \r | |
149 | like HardDisk.\r | |
150 | These device should contain a *fixed* blockIo\r | |
151 | protocol in their device handle.\r | |
152 | BDS will skip fixed blockIo devices, and NOT\r | |

154 | will help to delete those fixed blockIo boot option, \r | |
155 | whose description rule conflict with other auto-created\r | |
156 | boot options.\r | |
157 | 5. Non-BlockIo Simplefile - The boot option points to a device whose handle \r | |
158 | has SimpleFileSystem Protocol, but has no blockio\r | |
159 | protocol. These devices do not offer blockIo\r | |
160 | protocol, but BDS still can get the \r | |
161 | \EFI\BOOT\boot{machinename}.EFI by SimpleFileSystem\r | |
162 | Protocol.\r | |
163 | 6. File - The boot option points to a file. These boot options are usually \r | |
164 | created by user manually or OS loader. BDS will not delete or modify\r | |
165 | these boot options. \r | |
166 | \r | |
