402 | \r | |
403 | The Start() function is called to determine and to begin the platform\r | |

405 | be as simple as returning EFI_UNSUPPORTED if there is no EFI IPv4 Protocol\r | |

407 | from nonvolatile storage, downloading dynamic data from a DHCP server, and\r | |
408 | checking permissions with a site policy server.\r | |
409 | Starting the configuration policy is just the beginning. It may finish almost\r | |
410 | instantly or it may take several minutes before it fails to retrieve configuration\r | |
411 | information from one or more servers. Once the policy is started, drivers\r | |
412 | should use the DoneEvent parameter to determine when the configuration policy\r | |
413 | has completed. EFI_IP4_CONFIG_PROTOCOL.GetData() must then be called to\r | |
414 | determine if the configuration succeeded or failed.\r | |
415 | Until the configuration completes successfully, EFI IPv4 Protocol driver instances\r | |
416 | that are attempting to use default configurations must return EFI_NO_MAPPING.\r | |
