Speaking of 64bit ...
Note the address in the slide if you want to see the PDF files detailing the technical details of Intel's implementation. There is some question of exactly how much memory is addressable under what circumstances (AMD will only be addressing memory to 48bits), and hopefully these documents will clear that up.
In trying to understand exactly why Intel has done things the way they have, our research has turned up a couple interesting tidbits. The Intel validation process is a grueling one (as one could well imagine would develop after something as embarrassing as the original Pentium's FDIV error). It is possible that a lack of availability of software (specifically 64 bit drivers for 64 bit windows) is preventing Intel from properly completing its validation process and enabling the hardware. We have also heard rumors that Intel couldn't enable the 64 bit extensions in Prescott without the added connections provided by LGA775. This doesn't quite seem to fit either as Nocoma won't be launching with a new socket.
But we'll keep digging.
Wednesday was mostly about Intel spreading the word about how things are moving forward as planned. There were customers for Itanium there (HP, IBM, and Dell) who mainly just spent time talking about how much their company liked Itanium. There was mention of continued adoption of hotspots throughout through out the country.
The bright side of yesterday was the Technology Showcase and meetings with some of the other companies that are here at IDF. We will be bringing you a fun filled wrap up with all the juicy goodness of the show floor and other meetings tomorrow (as we still have a few meetings to cover today), but expect to see an article on Pat Gelsinger's keynote later today.
