Abstract

The present invention provides an electronic device including a write-once-then-read-only register, a chipset, a read-only memory, a flash memory and a central processor. The write-once-then-read-only register is arranged to store a determination value. The chipset is arranged to produce a CPU reset signal. The read-only memory is implemented in the chipset, and has a first memory block which corresponds to a predetermined address and is used to store a first instruction. The flash memory is coupled to the chipset, and has a second memory block which corresponds to the predetermined address and is used to store a second instruction. The central processor is arranged to determine the location of the predetermined address according to the CPU reset signal and the determination value.
