2 | This module produce main entry for BDS phase - BdsEntry. \r | |
3 | When this module was dispatched by DxeCore, gEfiBdsArchProtocolGuid will be installed\r | |
4 | which contains interface of BdsEntry.\r | |
5 | After DxeCore finish DXE phase, gEfiBdsArchProtocolGuid->BdsEntry will be invoked\r | |
6 | to enter BDS phase.\r | |
