Boot Device Selection Architectural Protocol as defined in PI spec Volume 2 DXE

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.
