Abstract: A host device and method for partitioning attributes in a storage device are provided. In one embodiment, a host device is provided that is in communication with a storage device storing a table associating logical address ranges with an encryption key and read/write permissions. The host device sends a request to the storage device to add a column to the table and then sends a request to the storage device to add an attribute to a cell of the added column to the table associated with a particular logical address range. The table and commands can be those compatible with the Trusted Computing Group's (TCG's) Opal standard.

Abstract: Methods, systems, and computer readable media for providing BIOS data and non-BIOS data on the same non-volatile memory. According to one aspect, a system for providing BIOS data and non-BIOS data on the same non-volatile memory includes a controller for controlling access by a host to a non-volatile memory for storing data, the data including BIOS data and non-BIOS data. The controller includes a first bus interface for communicating data to and from the host via a first bus of a first bus protocol, a second bus interface for communicating data to and from the host via a second bus of a second bus protocol, and a third interface for communicating data to and from the non-volatile memory. The first bus comprises a bus that is operable after power-on reset and before BIOS is accessed.

Abstract: A pressure sensitive stylus, comprises a movable tip that recedes within a housing of the stylus in response to user applied contact pressure, wherein a displacement of the tip along an axis on which it recedes is a function of the applied contact pressure, and an optical sensor enclosed within the housing for optically sensing the displacement of the tip and for providing output in response to the sensing.
