The properties table should not be used. It has been superseded by the memory attributes table, per spec. In edk2, the properties table is controlled by the PCD, regardless of the memory attributes table. In edk2, the memory attributes table is always produced, regardless of the properties table. Please see the discussion under: [edk2] [patch 0/7] Add UEFI2.6 MemoryAttributesTable support. http://mid.mail-archive.com/1454069539-4056-1-git-send-email-jiewen.yao@intel.com Thanks Laszlo 保密声明： 本邮件含有保密或专有信息，仅供指定收件人使用。严禁对本邮件或其内容做任何未经授权的查阅、使用、复制或转发。 CONFIDENTIAL NOTE: This email contains confidential or legally privileged information and is for the sole use of its intended recipient.
