摘要： This invention describes a set of methods and techniques that together address the deficiencies of the basic input/output system (BIOS) and the advanced basic input/output system (ABIOS) in the context of a pen-based portable computer while retaining much of its strengths in terms of providing an insulating layer between the hardware and the operating system such that the same operating system code body will execute in a variety of hardware platforms. In particular, the following deficiencies have been addressed. (a) A dual boot capability allowing the user to select, through a set-up procedure, either a conventional (DOS-style) booting procedure or a Penpoint-style booting procedure. (b) The capability to mast certain device characteristics from the operating system, defined as a callback mechanism. (c) A method for collecting and maintaining device state information of a device that could be disconnected or reconnected during the operating of the computer.
