Thanks, Dev ___ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel Hi Eric, Thanks for the response. I've taken a look at DriverSampleDxe in the past to get an understanding of Hii forms, From what I can tell I don't think there is a form present there that does what I'm asking for. Any chance you can point me to a line number or location in that driver that you think does what I'm trying to do correctly? -Dev ___ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
