Hi, Greg,
You can add the similar code in your project .fdf file to insert the prebuilt
UEFI driver.
FILE DRIVER = 3d696f3f-b3e3-4ca6-b299-2e7e5c7986b7 {
SECTION PE32 = $(PLATFORM_PACKAGE)/ThirdParty/IntelGopDriverRelease.efi
SECTION UI = "IntelGOP"
}
during DXE dispatching, the prebuilt UEFI driver can be found and loaded by
calling ENTRY_POINT function, just like other UEFI drivers.
Binding E823-L NAC happens during the PCIe device enumeration, the function,
EFI_DRIVER_BINDING_PROTOCOL.Supported() examines the binding criteria. You can
load the prebuilt UEFI driver, but you can't use the driver for your device.
Best Regards
Feng Libo

Loading Prebuilt EFI without INF in UEFIPayloadPkg.dscHi,
I am trying to automatically load an EFI file in EDK2, before the UEFI Shell is
available.
It is a prebuilt UNDI Network Driver from Intel, E4297X8.EFI, from the
complete Ethernet Drivers package zip file. ..\Release_29.3\APPS\EFI\EFIx64
The Open Source ICE driver doesn't contain bindings for the E823-L NAC we
have, even though it is part of the E800 series of Network Controller.
Is there a way to build an INF file, that doesn't have an entry point, to load
the preexisting E4297X8.EFI file? I hope there is a way to "embed" it in the
built payload, being loaded through Slimboot.
Kind regards.
Greg.
