Hello ZClarkWilliams:

Could you please help to clarify if NetworkStack MUST install the LoadFile2 Protocol or not. With reference to the below spec item, the LoadFile2 protocol must be implemented.

In one of the BIOS environment, the Setup Browser Locates the LoadFile2 instance of Network Boot Device and it not found as it not installed by the current NetworkPkg.

Can you please comment if there is any reason behind not installing during the HTTP Boot.
“UEFI SPEC

Drivers can be implemented by platform firmware developers to support buses and devices in a specific platform. Drivers can also be implemented by add-in card vendors for devices that might be integrated into the platform hardware or added to a platform through an expansion slot. The following list includes possible driver features, and the UEFI elements that are required for each feature type:

  1.  If a driver is written for a boot device that is not a block-oriented device, a file system-based device, or a console device, then the EFI_LOAD_FILE2_PROTOCOL must be implemented.

Thanks
Siva
