Thanks for your reply.

A few more questions please:

1. In general, not in the Minnowboard environment, but in the Microsoft Windows environment, are EmbeddedDrivers usually specified?

2. Should the ‘EmbeddedDrivers’ parameter be assigned to ‘FmpDxe.efi’? or assigned to ‘SystemFirmwareUpdateDxe.efi’(in SignedCapsulePkg)?
Thank you for your help!
