PURPOSE:To give various complicated security levels by offering individual information of security to a floppy disk. CONSTITUTION:A RAM (system program) 2 and ROM BIOS (basic input output system) part 9 include a security control program and control the access of disk resources of a hard disk (HD) 3 and a floppy disk (FD) 6 through an FD/HD interface 5. A CMOS part 8 for machine individual information storage is controlled through a CMOS access interface 7 by the RAM 2 and the ROM BIOS part 9. That is, individual information of security is offered by the floppy disk 6 in the security check system. Thus, various complicated security levels are given, and it is unnecessary for a user to input these information at each time of access because they are set at the time of start. |
