Titan 1.2 is available since quite a while - the dust on my board is proof ;-) Since Titan 1.0 and 1.0 were shipped in very low numbers to early customers only and will never be available in volume production the support for them was removed. As I recall there were at least these problems with Titan 1.0 and 1.1 in Linux: - Linux uses the prefetch prepare for store operation. - Coherency mode 5 which is mandatory for good performance and any kind of sanity on SMP is now being used. - The problem with the third ethernet port which Manish just had described. You can dig through XCVS, WebCVS or the linux-cvs archive to find where I broke backward compatibility. Ralf
