Abstract
A method for executing a system management interrupt (SMI) is provided. When a power on self test (POST) is executed, a first identifier is generated and stored into a system management mode block of a memory. During a process for starting an operating system (OS), the first identifier is read from the system management mode block as a second identifier, and the second identifier is stored into an OS block of the memory. When the OS wants to use a system management interrupt, the first identifier and the second identifier are respectively read from the system management mode block and the OS block. Afterwards, it is determined whether the first identifier and the second identifier are the same. If the first identifier and the second identifier are the same, the SMI is executed.
