摘要： A method is described that includes detecting that a memory access of system management mode program code is attempting to reach program code outside of a protected region of memory by comparing a target memory address of a memory access instruction of the system management program code again information that defines confines of the protection region. The method also includes raising an error signal in response to the detecting.
摘要翻译： 描述了一种方法，其包括通过将系统管理程序代码的存储器访问指令的目标存储器地址再次比较来检测系统管理模式程序代码的存储器访问尝试到达存储器的受保护区域之外的程序代码， 定义保护区域的范围。 该方法还包括响应于检测而提高误差信号。
