AMD cites chips that don't do Windows 7 'XP mode'

Select processors from Advanced Micro Devices do not support Windows 7 'XP mode,' though, like Intel, the vast majority of shipping processors do support XP mode.

Select processors from Advanced Micro Devices do not support Windows 7 "XP mode" though, like Intel, the vast majority of shipping processors do support XP mode.

Microsoft describes XP mode on its Web site as follows: "As part of the upcoming Windows 7 Release Candidate milestone, Microsoft will release a beta version of Windows XP Mode, which allows users of Windows 7 Professional and above to launch many older Windows XP productivity applications directly from their Windows 7 desktop. The Windows XP Mode stand-alone feature is specifically designed to help small businesses that are using Windows XP applications move to Windows 7. For larger businesses, Microsoft Enterprise Desktop Virtualization (MED-V) MED-V 2.0 builds on top of Windows Virtual PC and provides centralized management of Windows XP Mode. MED-V 2.0 will be available in beta within 90 days of general availability of Windows 7."

"All CPUs AMD is currently shipping, except Sempron, include AMD-V and therefore support XP mode," an AMD spokeswoman said Wednesday.

AMD also cited processors that are not necessarily shipping currently. "With the exceptions of Sempron-branded processors and Turion K8 Rev E processors, all notebook processors shipped by AMD include AMD-V and therefore support Windows 7 XP mode," AMD said. "With the exceptions of Sempron-branded processors and pre-Rev F Athlon branded processors, all of the desktop processors shipped by AMD include AMD-V and therefore support Windows 7 in XP mode."

And Opteron processors: "Also, all AMD Opteron processors shipped by AMD from Rev F forward include AMD-V," according to AMD.

A quick search on Best Buy's Web site turned up very-low-end systems that use the Sempron processor. For example, a $329.99 Acer desktop is currently being sold with a Sempron processor. And on Hewlett-Packard's Web site, an HP Compaq dx2450 Microtower (starting at $329), for example, can be configured with a number of different Sempron processors.

Dell has sold laptops, such as the Latitude D531, with AMD Mobile Sempron processors.

An earlier Nanotech: The Circuits Blog post cited Intel processors that do not support XP mode. Intel spokesman Nick Knupffer asserts this won't be a big issue. "Having VT (Virtualization Technology) on these consumer laptops is not going to be an issue--because the consumer versions of Windows 7 (Starter, Home Basic, and Home Premium) do not include Windows XP Mode," he writes.

Jaguar F-type S Coupe is beautiful and impractical

With stunning lines and sharp handling, the F-type S Coupe is an excellent sports car, and as impractical as a true sports car should be.
