US 8,266,418 B2 · Computer system and method of booting the same

Abstract

Provided are a computer system and a method of booting the same. The computer system includes: a first storage unit for storing a booting-related program including an operating system program and data, the stored program and data being retained even when a power voltage is not supplied; and a second storage unit for storing data, the data being lost when the power voltage is not supplied for a predetermined time or longer. The method includes: a first step of performing a booting operation using the booting-related program stored in the first storage unit and storing the booting-related program stored in the first storage unit in the second storage unit when the second storage unit is detected and the booting-related program is not stored in the second storage unit; a second step for performing a booting operation by executing the booting-related program stored in the second storage unit when the second storage unit is detected and the booting-related program is stored in the second storage unit; and a third step of backing up the booting-related program stored in the second storage unit to the first storage unit when a predefined backup condition is met.

Dependent claims

A computer system comprising:

a first storage unit for storing a booting-related program including an operating system program and data, and retaining the stored program and data even when a power voltage is not supplied;
and
a controller for:
determining whether a second storage unit is connected to the computer system, the second storage unit being an external apparatus and volatile,
performing a booting operation by executing the booting-related program stored in the first storage unit when the second storage unit is not connected to the computer system,
determining whether the booting-related program is stored in the second storage unit when the-second storage unit is connected to the computer system,
performing the booting operation by executing the booting-related program stored in the first storage unit and after performing the booting operation storing the booting-related program stored in the first storage unit in the second storage unit when the booting-related program is not stored in the second storage unit,
performing the booting operation by executing the booting-related program stored in the second storage unit when the booting-related program is stored in the second storage unit, and
backing up the booting-related program stored in the second storage unit to the first storage unit when a predefined backup condition is met.
