Typedef Documentation

Declare forward reference for the BDS Architectural Protocol

This function uses policy data from the platform to determine what operating system or system utility should be loaded and invoked. This function call also optionally make the use of user input to determine the operating system or system utility to be loaded and invoked. When the DXE Core has dispatched all the drivers on the dispatch queue, this function is called. This function will attempt to connect the boot devices required to load and invoke the selected operating system or system utility. During this process, additional firmware volumes may be discovered that may contain addition DXE drivers that can be dispatched by the DXE Core. If a boot device cannot be fully connected, this function calls the DXE Service Dispatch() to allow the DXE drivers from any newly discovered firmware volumes to be dispatched. Then the boot device connection can be attempted again. If the same boot device connection operation fails twice in a row, then that boot device has failed, and should be skipped. This function should never return.

Parameters:
This The EFI_BDS_ARCH_PROTOCOL instance.
Returns:
None.
