147 | 2. Shell - The boot option points to internal flash shell. \r | |
148 | Bds will try to automatically create this type boot option when enumerate.\r | |
149 | 3. Removable BlockIo - The boot option only points to the removable media\r | |
150 | device, like USB flash disk, DVD, Floppy etc.\r | |
151 | These device should contain a *removable* blockIo\r | |
152 | protocol in their device handle.\r | |

166 | protocol. These devices do not offer blockIo\r | |
167 | protocol, but BDS still can get the \r | |
