When the keyboard controller 17 instructs execution of the instant on function, a signal for controlling the Linux operating system to be uploaded to the main memory 13 and to read the Linux operating system from the hard disk 16 is then generated. step).

The Linux uploaded to the main memory 13 in step 218 is booted by the ROM BIOS, and an instant on player is executed under the Linux operating system (step 221).

The instant on player supports various audio formats (CDDA, MP3) and video formats (DVD, DVD + VR, DVD-VR, VCD, SVCD). As shown in step 221, the instant on player is executed on the display unit 8 of FIG. 1.

In step 221, the instant on player is executed, and since the button selected in step 215 is a DVD button, the DVD mode is performed on the instant on player to perform DVD playback (step 224).

Therefore, the user selects the DVD button 4 once, and thus is performed at once from power on to system booting, instant on player execution, and DVD playback, thereby providing convenience and convenience in use.

Next, when the system is off (step 200) and the button selected by the user is not a DVD button and the music button 5 is selected (step 227), the keyboard controller 17 analyzes the signal and instant-on. It is determined that the signal corresponds to the function.

When the keyboard controller 17 instructs execution of the instant on function, the Linux operating system is read from the hard disk 16 and the Linux operating system is controlled to be uploaded to the main memory 13 (step 230).

Linux uploaded to the main memory 13 in step 230 is booted by the ROM BIOS, and an instant on player is executed under the Linux operating system (step 233).

The instant on player supports various audio formats (CDDA, MP3) and video formats (DVD, DVD + VR, DVD-VR, VCD, SVCD). As shown in step 233, the instant on player is illustrated in the display unit 8 of FIG. 1.

In step 233, the instant on player is executed, and since the button selected in step 227 is a music button, a music mode is performed on the instant on player to play a CD or an MP3 file (step 236).

Therefore, the user selects the music button 5 once, and thus is performed at once from power on to system booting, instant on player execution, and music playback, thereby providing convenience and convenience in use.

Next, when the system is off (step 200), if the button selected by the user selects the power button 3 other than the DVD button 4 and the music button 5 (step 203), the keyboard controller 17 Analyze the signal and determines that the signal corresponds to a normal operating system boot.

The keyboard controller 17 reads the Windows operating system from the hard disk 16 and controls the Windows operating system to be uploaded to the main memory 13 (step 206).

Then, the window is booted (step 209), and then the application program of a specific function selected by the user is executed under the Windows operating system (step 212). The operation process of the application program under the Windows operating system is performed in the same manner as in the prior art.

Therefore, in the present invention, the power button 3, the DVD button 4, and the music button 5 all operate as buttons for supplying power to the system. The DVD button 4 and the music button 5 operate as buttons for instructing the instant on player to be executed after the Linux operating system is booted and serially performing DVD or music playback in the instant on player. .
