ABSTRACT:
Methods, systems, and computer-readable media service PS/2 devices within an extensible firmware interface (EFI) environment where the PS/2 devices provide data via a keyboard controller. The method involves receiving a request for data from an EFI driver, in response to receiving the request, determining whether data from any of the PS/2 devices is available for delivery to one or more EFI drivers via the keyboard controller. The method further involves in response to determining that the data is available for delivery, dispatching the data from the keyboard controller based on which PS/2 devices provided the data and forwarding the data to the EFI drivers associated with a PS/2 device providing at least some of the data.
