2 | The entry of the embedded BDS. This BDS does not follow the Boot Manager requirements\r |
3 | of the UEFI specification as it is designed to implement an embedded systmes\r | |
2ef2b01e A |
4 | propriatary boot scheme.\r |
5 | \r | |
3402aac7 | 6 | This template assume a DXE driver produces a SerialIo protocol not using the EFI\r |
2ef2b01e A |
7 | driver module and it will attempt to connect a console on top of this.\r |
