1. An information device comprising:
- a first wireless module which performs wireless communication in accordance with a first communication way;
a second wireless module which performs wireless communication in accordance with a second communication way;
means which selects either one of said first and second wireless modules; and
a control unit which, when said first wireless module is selected by said selection means, disenables wireless communication via said second wireless module and then enables said first wireless module, and when said second wireless module is selected, disenables wireless communication via said first wireless module and then enables said second wireless module.

Abstract
This invention provides an information device which disenables unselected wireless devices by directly controlling hardware, and thus can prevent interference between wireless devices using the same frequency band. In this invention, a BIOS controls an EC for a wireless module selected based on a user instruction, thereby controlling power supply to a Bluetooth module and power supply to a wireless LAN module. This makes it possible to enable either one of the modules and disenable the other module.

4. An information device comprising:
-
a Bluetooth wireless module which performs wireless communication in accordance with a Bluetooth standard;
a wireless LAN unit which performs wireless communication in accordance with an IEEE 802.1b standard;
a first utility which determines a selected wireless module on the basis of a user instruction, and when the selected wireless module is determined as said Bluetooth wireless module, instructs to power off said wireless LAN unit;
a second utility which instructs to turn on said Bluetooth wireless module on the basis of the instruction from said first utility that represents power off of said wireless LAN unit;
a BIOS which instructs to power off said wireless LAN unit on the basis of the instruction from said first utility, and instructs to power on said Bluetooth wireless module on the basis of the instruction from said second utility; and
a controller which controls to stop power supply to said wireless LAN unit on the basis of the instruction from said BIOS that represents power off of said wireless LAN unit, and which, upon receiving the instruction from said BIOS that represents power on of said Bluetooth wireless module, controls to supply power to said Bluetooth wireless module after said wireless LAN unit is powered off. - View Dependent Claims (5, 6, 7, 8, 9, 10)

11. A wireless module switching method in an information device having a first wireless module which performs wireless communication in accordance with a first communication way, and a second wireless module which performs wireless communication in accordance with a second communication way, comprising:
-
determining based on a user instruction whether a selected wireless module is the first wireless module; and
when the selected wireless module is determined as the first wireless module, enabling the first wireless module and disenabling the second wireless module, and when the selected wireless module is not determined as the first wireless module, disenabling the first wireless module and enabling the second wireless module.

12. An information device comprising:
-
a first wireless module which performs wireless communication in accordance with a first communication way;
a second wireless module which performs wireless communication in accordance with a second communication way;
means which can select either one of said first and second wireless modules;
a BIOS which, when said first wireless module is selected by said selection means, instructs to stop power supply to said second wireless module and then instructs to supply power to said first wireless module, and when said second wireless module is selected by said selection means, instructs to stop power supply to said first wireless module and then instructs to supply power to said second wireless module; and
a controller which powers off either one of said first and second wireless modules and then powers on the other one of said first and second wireless modules on the basis of an instruction from said BIOS.

13. A wireless module switching method in an information device having a first wireless module which performs wireless communication in accordance with a first communication way, and a second wireless module which performs wireless communication in accordance with a second communication way, comprising:
-
determining which of the first and second wireless modules has been selected, and notifying a BIOS of the information device of a determination result from selection means;
causing the BIOS to instruct to stop power supply to the second wireless module and then instruct to supply power to the first wireless module in accordance with a notification that the first wireless module has been selected, and to instruct to stop power supply to the first wireless module and instruct to supply power to the second wireless module in accordance with a notification that the second wireless module has been selected; and
powering on/off the first and second wireless modules on the basis of the instruction from the BIOS.
