Abstract: Methods and apparatus to provide conditional legacy support are disclosed. In particular, the methods and apparatus initialize a processor in a pre-boot environment using a first computer readable medium. The processor determines if the legacy support is required and selectively locates and loads a compatibility support module into the processor from a second computer readable medium if the processor requires legacy support.

Abstract: A pen-based portable personal computer can emulate the functions of a standard two-button mouse. In particular the system can emulate standard movement and clicking of a mouse buttons as well as emulate both left and right mouse buttons of a two-button mouse. In order to be compatible with various application programs, the system can also emulate the double clicking of the mouse button.

Abstract: The present invention relates to a wireless interface device and more particularly to a wireless interface device for interfacing with a host computer connected in either a wired or wireless local area network. Once a connection is made between the wireless interface device and a host computer, the host computer is under the control of the wireless interface device. In order to provide a convenient way to return control back to the host computer, a hot icon is provided on the wireless interface device which, in response to a pen-down event, automatically returns the control back to the host computer.

Abstract: A wireless interface device is adapted to be interfaced with a host computer by way of a radio link. A wireless interface device includes one or more flash memory devices that are adapted to be updated by the host computer over the radio link.
