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.
