PROBLEM TO BE SOLVED: To provide a method for accessing to a legacy device on a computer, without increasing hardware size, cost and power consumption. SOLUTION: This method of providing hardware access to an OS concerned in the present invention includes allocating a portion of firmware address space of a data processing arrangement for use as a virtualized data interface that emulates a first hardware device (504), presenting the virtualized data interface to the OS (504), accessing to the virtualized data interface using a standardized kernel component of the OS adapted to interface with the first hardware device (506), and exchanging of data between the virtualized interface and a second hardware device based on access of the virtualized data interface by the OS via the standardized kernel component (508).
