Re: the beta version of Whistler (in particular, what was used in the article) is most likely in fact using true software emulation and not the internal x86 Quite possibly they were. And why would they do such a thing? Well, keep in mind that Itanium/McKinley doesn't support 3 modes like hammer. Hammer can run 32, mixed 32/64, or pure 64. Itanium/McKinley runs only 32 or 64. Unless you are going to give up all possibility of using the 64 bit execution units of Itanium/McKinley (not a bad idea unless/until there is some software for it) it may be that you can't use the 32 bit hardware in Itanium/McKinley. Did you ever wonder why it would have been necessary to write and include in Microsoft's OS a software emulator for X86 when the chip supposedly has hardware to execute these instructions? That's quite a bit of pointless work for Microsoft to take on, unless the X86 unit on Itanium/McKinley hasn't worked to date and isn't expected to work for a long time - if ever. Dan
