* AMD’s ATI Radeon™ X and Radeon™ 9550
series of GPUs are capable of processing HDCP signals ("HDCP ready"),
however not all ATI Radeon graphics cards are HDCP ready. Please check
the applicable ATI Radeon graphics card specification to determine
if a particular ATI Radeon graphics card is HDCP ready. Some third
parties manufacture graphics cards containing ATI Radeon GPUs -- you
can inquire of them which models, if any, are HDCP ready. In addition,
playing HDCP content requires additional HDCP ready components, including
but not limited to an HDCP ready monitor, disc drive, multimedia application
and computer operating system.

*** ATI HyperMemory2 is an optional feature that may not be
implemented in some board configurations. ATI HyperMemory is the cumulative
total of local
and system
memory used by the Graphics Processing Unit (GPU) intended for use
in the processing and creation of 3D and other images. The amount of
HyperMemory is determined by the amount of local memory and available
system memory.
