Any thoughts Kevin? Before this commit, the gPXE e1000 rom was able to successfully netboot when selected as a boot device. With this commit, we get a "device not found" error within gPXE when launched as a boot device but when run from the gPXE command line, it launches successfully. Regards, Anthony Liguori
