BIOS-Rom computer system having BIOS-Rom and method for storing data in BIOS-Rom

摘要

PURPOSE: A BIOS ROM, a computer system having the BIOS ROM, and a method for storing the BIOS ROM are provided to store important information with safety by protecting the information against a virus, a mistake of a user, or a physical damage. CONSTITUTION: If a power source is applied to a system(S10), a BIOS unit executes a POST(Power On Self Test)(S20) and boots the system by operating an operating system stored in a hard disk drive of the system(S30). In the case that predetermined information is stored or read by accessing a storage of a BIOS ROM, a user generates an interrupt for calling a control unit provided in the BIOS ROM. The control unit is operated and requests that the user inputs a system password(S40). If the user inputs a predetermined password, the control unit checks whether the inputted password identified with a system password stored in the storage(S50). If two passwords are identified therewith, the control unit calls a memory address of the storage out of memories of the BIOS ROM and enable the user to access(read, write) to the storage. Thus, the user stores predetermined application information in the storage or reads information stored in the storage(S60).
