Just a little bit calrification here:
The  Virtex-4VFX12  of  ML403 does not have RocketIO serial transceivers.
However,  the Virtex-4VFX20 FPGA and other > FX20 do have
RocketIO serial transceivers.  The only problem is that we did'nt
find one development board equipped with the Virtex-4VFX20 FPGA
yet.  Do'nt know if it will.  If anyone knows about it, we will appreciate
the information.

Thanks,
