Customers can now purchase workstations using Intel ‘s Nocona Xeon processor, with 64-bit extensions to the x86 instruction set, but they can’t run the beta 64-bit version of Windows designed for those extensions on the new workstations. The publicly available beta version of Windows XP 64-Bit Edition for 64-Bit Extended Systems can only be installed on systems with AMD Opteron and Athlon 64 processors. A beta version of Windows compatible with Intel’s 64-bit extensions technology is expected to be released by the end of next month. Intel is planning to introduce a server chipset for its Nocona Xeon processors in August, right around the time the new beta version is expected. Intel and Microsoft have promised that the final versions of both Windows XP and Windows Server 2003 for 64-bit extended systems will run on Xeon and Opteron servers without any hitches. The production version of the operating system is expected in the fourth quarter.
