Abstract:
This invention discloses an electronic apparatus having multiple operating systems and a data modification method thereof. The method comprises: a first operating system is executed on the electronic apparatus; an input data is received under the first operating system; then, under the first operating system, the input data is set into a second operating system; and, when the second operating system is executed on the electronic apparatus, the second operating system operates according to the input data. With the method, the electronic apparatus having multiple operating systems can be used in a more flexible manner, and the data modifying or data synchronization can be more conveniently performed.
Abstract:
A keyboard includes at least one special symbol key, a controller and a middleware. The controller asserts a code signal when the special symbol key is depressed. The middleware performs a matrix mapping procedure to convert the code signal into a new one conforming to an operation system of the data processing device if the code signal is not identical to that of the operation system.
