SPIN, nice selective editing, taking crappy english into account (and I've seen much worse here in official documentation from local companies) I go with Ramsey's explanation... now skip down a line where it says this: "The PC21100 is fully released product, but because of our PC focus, we are only selling to those, speciallized accounts" The Compaq link is here. <A HREF="http://www.cluster-labs.com/download/CL_DS_CPU450_V1_01.pdf" target="_new">http://www.cluster-labs.com/download/CL_DS_CPU450_V1_01.pdf</A> and it is available now... <A HREF="http://www.bladeserver-direct.com/us/index.html" target="_new">http://www.bladeserver-direct.com/us/index.html</A> click on 'Products', 'Blade Server Cards...' then 'Blade Server CPU 450 P4 2.0 GHz' (full link is an https link that will not be hot...) (data sheet at <A HREF="http://www.bladeserver-direct.com/pdf/DS_CPU450.pdf" target="_new">http://www.bladeserver-direct.com/pdf/DS_CPU450.pdf</A> is the same as linked above, WITH TPM reference) Believe what you want.
