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