The present invention relates to a computer having a multi-boot power button, a peripheral device, and a method of operating the same, and more particularly, to a computer device capable of performing a multi-boot using a plurality of power buttons.

Booting refers to loading an operating system into computer memory (RAM). Once the operating system is loaded, you can run multiple applications. Recently, a user's computer environment is diversified to install a plurality of operating systems on a hard disk and to boot to a desired operating system by the user's choice when booting.

For example, you can install DOS, Win95 / 98, or Linux at the same time on your computer's hard disk, and select a specific operating system to boot at boot time. As such, there are several ways to multiboot by installing multiple operating systems such as Win9X or Linux on one or more hard disks, and the details may vary slightly depending on the installation distribution.

Hereinafter, referring to FIG. 1, a flowchart illustrating a conventional multibooting procedure is shown.

First, in step S100, when the user presses the power button, in step S110, an electrical signal is transmitted to the CPU, and the CPU performs a series of system check operations called POST. In step S120, the CPU checks whether there is a key input corresponding to a specific operating system among the plurality of operating systems, and in step S130, boots the computer with an operating system corresponding to the input key.

However, this conventional multi-booting procedure is inconvenient to select the desired operating system through the user's keyboard operation during booting. That is, it is inconvenient to go through a power button input procedure and an operating system selection procedure.

Accordingly, the present invention has been made to solve the above problems, by providing a power button corresponding to each operating system, a computer, a peripheral device and a method of operating the same can be booted to the desired operating system with a single power button operation Its purpose is to provide
