Abstract

A memory emulating apparatus and its method are proposed to emulate a read-only memory (ROM) of a motherboard. The motherboard has a first or a second ROM socket. The present invention includes a first and second connectors for connecting with the first and the second ROM socket respectively, a rewritable memory for storing a system code and a controller connected with the first and second connectors and the rewritable memory. If the first connector is connected to the first ROM socket, the controller enters a first access mode to access the system code and passes it to the first ROM socket via the first connector. Otherwise, if the second connector is connected to the second ROM socket, the controller enters a second access mode to access the system code and passes it to the second ROM socket via the second connector for the motherboard to check.

Dependent claims

A memory emulating apparatus, used to emulate a read-only memory (ROM) of a motherboard, the motherboard having a first ROM socket or a second ROM socket disposed thereon, the memory emulating apparatus comprising:

a first connector for connecting with the first ROM socket;
a second connector for connecting with the second ROM socket;
a rewritable memory having a system code stored therein;
and
a controller connecting with the first connector, the second connector and the rewritable memory;
wherein if the first connector is connected to the first ROM socket and the motherboard is activated, the controller enters a first access mode to access the system code and passes the system code to the first ROM socket via the first connector for executing the system code;
otherwise, if the second connector is connected to the second ROM socket and the motherboard is activated, the controller enters a second access mode to access the system code and passes the system code to the second ROM socket via the second connector for executing the system code.

4 more elements

A memory emulating method, applied for a memory emulating apparatus connecting with a motherboard, the motherboard having a first read-only memory (ROM) socket or a second ROM socket disposed thereon, the memory emulating method comprising:

providing a first connector for connecting with the first ROM socket;
providing a second connector for connecting with the second ROM socket;
and
loading a system code into a rewritable memory of the memory emulating apparatus;
wherein if the first connector is connected to the first ROM socket and the motherboard is activated, the method further has a step of entering a first access mode to access the system code and passing the system code to the first ROM socket via the first connector for executing the system code;
otherwise, if the second connector is connected to the second ROM socket and the motherboard is activated, the method further has a step of entering a second access mode to access the system code and passing the system code to the second ROM socket via the second connector for executing the system code.
