Original Abstract Submitted

an operating system (os) software service detects an accessibility change event and takes a snapshot of the accessibility settings before sending and receiving memory-mapped input/output (mmio) commands with an embedded controller (ec) to establish trust using existing security hardening methods. the software service may send an mmio command that includes the profile as a payload to the ec. the ec extracts the profile payload and saves it to an nvram variable before signaling a basic input/output system (bios) during early boot of an available accessibility profile. the ec publishes an accessibility profile presence to a bios pre-efi initialization (pei) layer, which sends a command to the ec to return the response. the bios creates a new hand off block (hob) command indicative of the accessibility profile and passes this to an early driver execution environment (dxe) stage, which reads the hob data and locates the accessibility layer within a serial peripheral interface (spi) firmware volume and loads into memory. this extracted profile information is passed onto the accessibility layer, which applies the profile data to user interface (ui) control attributes.
