Boot Logo 2 Protocol is used to convey information of Logo dispayed during boot.
|
|
|
|
The Boot Logo 2 Protocol is a replacement for the Boot Logo Protocol. If a
|
|
platform produces both the Boot Logo 2 Protocol and the Boot Logo Protocol
|
|
then the Boot Logo 2 Protocol must be used instead of the Boot Logo Protocol.
