Abstract
A computer system includes a central processing unit (CPU), system read-only memory (ROM), a random access memory (RAM) and a system controller. The system ROM includes a reset vector. A portion of the RAM is used to shadow the system ROM. The system controller is connected between the CPU, the system ROM and the RAM. The system memory includes an internal memory for storing first data. The system memory also includes logic which, in response to receiving an access to a reset vector stored in the system ROM, returns the first data stored in the internal memory.
