US 2007/0168585 A1 · Method and System for Remote Access to Keyboard Control in Legacy USB Mode

Abstract

A remote access module associated with a BIOS of an information handling system having a UHCI-based USB controller allows selection of legacy USB control with a local keyboard or access by a remote keyboard through a remote access bus master adapter. Input from an inactive local or remote keyboard results in automated enabling of the inactive keyboard and disabling of the active keyboard. In one embodiment, remote access to a keyboard port during legacy USB control saves the data associated with the remote access to a memory location accessible to the BIOS and invokes the BIOS to obtain the data. In another embodiment, a legacy USB control option is offered by a display to a user associated with a local keyboard and legacy USB control disabled if the user fails to select local access in a predetermined time period.

Dependent claims

An information handling system comprising:

one or more processors operable to process keyboard inputs;
a UHCI USB controller operable to accept keyboard inputs from a local keyboard;
a BIOS interfaced with the processor and operable to communicate the keyboard inputs from the UHCI USB controller to the processor with legacy USB support;
a remote access adapter interfaced with the processor and operable to accept keyboard inputs from a remote keyboard;
and
a remote access module associated with the BIOS and operable to selectively enable keyboard inputs to the processor from one of the UHCI USB controller or the remote access adapter during legacy USB support operations.
