3The T4240QDS is a high-performance computing evaluation, development and test
4platform supporting the T4240 QorIQ Power Architecture processor. T4240QDS is
5optimized to support the high-bandwidth DDR3 memory ports, as well as the
6highly-configurable SerDes ports. The system is lead-free and RoHS-compliant.
