A method and computer system for accessing memory through a system management interrupt is disclosed. The computer system contains a CPU, a chipset and a memory unit. When the CPU receives a system management interrupt signal, the computer system enters a system management mode. In one embodiment, a software interrupt is invoked for achieving the purpose of accessing the memory space beyond 1 Mbytes. A system management interrupt signal is generated by the chipset while a software interrupt service routine associated with the software interrupt is running. The memory space beyond 1 Mbytes can therefore be accessed while the system management interrupt handler routine relative to the system management interrupt signal is running.
