SUMMARY
This article outlines the support policy for using 32-bit Microsoft Windows XP with the Advanced Micro Devices (AMD) Opteron processor.

Microsoft Product Support Services will support x86-based Windows XP Home and Professional versions when they run on AMD Opteron-based systems. The level of support for Windows XP on specific hardware is determined by one of the following criteria:
 * Whether the hardware and drivers have completed the Microsoft Hardware Logo Program
 * Whether the hardware is listed on the Hardware Compatibility List (HCL)

To download the latest Windows HCL, visit the following Microsoft Web site:

For more information about the support of non-HCL hardware, click the following article number to view the article in the Microsoft Knowledge Base:

255036 Microsoft support policy on hardware not on Windows NT HCL

Note the following about AMD64-based systems:
 * AMD64-based systems can run both 32-bit versions of Windows and any 32-bit application that is supported by x86-based systems.
 * 32-bit versions of Windows on AMD64 cannot execute 64-bit code. Running 64-bit code requires a 64-bit operating system.
 * AMD64 processors cannot run Microsoft Windows XP 64-Bit Edition for Intel Itanium processors. The differences in architecture between the two processors prevent each from running Windows XP compiled for the other one.

For system builders
AMD's Opteron processor is available as a self-test eligible microprocessor when submitting a system for a logo. To obtain the list of self-test eligible microprocessors, visit the following Microsoft Web site:
