METHODS FOR DYNAMICALLY SELECTING A BOOTING OPERATING SYSTEM AND APPARATUSES USING THE SAME

摘要

The invention introduces a method for dynamically selecting a booting OS (Operating System), executed by a micro-controller of an apparatus, which contains at least the following steps. The micro-controller detects a selection signal output from a selection unit, and determines which one of two ROMs (Read-Only Memories) is to be activated accordingly. After a CS (Chip Select) signal of the determined ROM is asserted, a firmware stored in the determined ROM is loaded and executed, and an OS corresponding to the firmware, which is stored in a storage device, is loaded and executed.

1. A method for dynamically selecting a booting OS (Operating System), executed by a micro-controller of an apparatus, comprising:
detecting a selection signal output from a selection unit; determining which one of a first ROM (Read-Only Memory) and a second ROM is to be activated according to the selection signal; asserting a CS (Chip Select) signal of the determined ROM; loading and executing a firmware stored in the determined ROM; and loading and executing an OS corresponding to the firmware, which is stored in a storage device.
