Please try your command in Q35. I have root caused the issue to the incorrect implementation of LegacyRegion2 protocol.

I tried qemu 2.5, with and without kvm. For both, the command: > mem 0xfffec 4 showed the VTF0 signature. (Indicating that the flash was mirrored under 1MB.) Or, were you looking at RAM below 0xa0000? What command did you try? -Jordan _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org<mailto:edk2-devel@lists.01.org> https://lists.01.org/mailman/listinfo/edk2-devel _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
