Expansion module system and control method therefor
First Claim
1. An information processing system in which an expansion module, including devices such as a communication module, is built in, comprising:
- a first ID recording unit in which ID information, which identifies said information processing system, is recorded;
a second ID recording unit in which a copy of the ID information in said first ID recording unit is recorded when said expansion module is initialized;
an ID comparison unit that compares the ID information recorded in said first ID recording unit with the ID information recorded in said second ID recording unit when said expansion module is used; and
a module control unit that controls whether said expansion module is to be operated according to the comparison result of said ID comparison unit, wherein said module control unit makes said expansion module available for use if the ID information in said first ID recording unit matches the ID information in said second ID recording unit.

Abstract
An expansion module has a standard interface, such as USB or a PC card, with its outward shape structured to allow the expansion module to be exclusively used with the drive unit of a recording medium. An information processing system includes a first ID recording unit in which the ID of the information processing system is recorded, a second ID recording unit in which a copy of the ID information in the first ID recording unit is recorded when the expansion module is initialized, an ID comparison unit that compares both ID information when the expansion module is used, and a module control unit that controls whether the expansion module is to be operated, wherein, if the ID information in the first ID recording unit matches the ID information in the second ID recording unit, the expansion module can be used.

10. An information processing system comprising a wireless base station and an information processing system main body, said information processing system main body including an expansion module that includes devices such as a communication module for communicating with said wireless base station, said information processing system comprising:
-
a first ID recording unit in which ID information for identifying said information processing system is recorded;
a second ID recording unit in which a copy of the ID information in said first ID recording unit is recorded for each piece of identification information on said communication module when said communication module is initialized;
an ID comparison unit that compares the ID information recorded in said first ID recording unit with the ID information recorded in said second ID recording unit when said expansion module is used; and
a module control unit that controls whether said expansion module is to be operated according to the comparison result of said ID comparison unit, wherein said module control unit compares the ID information in said first ID recording unit with the ID information in said second ID recording unit for each piece of identification information on said communication module when said communication module is used and, if a match occurred in the ID information, makes said communication module available for use. - View Dependent Claims (11, 12, 13, 14, 15)

16. A control method for an information processing system in which an expansion module, including devices such as a communication module, is built, said control method comprising the steps of:
-
reading ID information, which denitrifies said information processing system, from a first ID recording unit when said expansion module is initialized;
recording the ID information in a second ID recording unit;
comparing the ID information recorded in said first ID recording unit with the ID information recorded in said second ID recording unit when said expansion module is used; and
controlling whether or not said expansion module is used according to the comparison result of the ID information. - View Dependent Claims (17, 18, 19, 20)
