The Microsoft Windows hardware compatibility list (HCL) is a compilation of computers and computer hardware that have been extensively tested with Windows for stability and compatibility. Microsoft Product Support Services (PSS) uses the HCL to determine whether or not particular hardware is supported for use with the Windows operating system.
Before you install Windows on a computer, check the HCL to determine whether the computer is certified by Microsoft as Windows-compliant.
For additional information about hardware that is supported on a Windows XP-based system, click the article number below to view the article in the Microsoft Knowledge Base:

A hardware device is not supported if it is not listed on the HCL. For a computer to be considered an HCL-compliant system, the computer must be listed on the HCL. If a computer is not listed on the HCL, but it is built with hardware that is listed on the HCL (for example, a motherboard from a referenced system, an approved SCSI controller, an approved video adapter, and an approved network card), it is still not considered an HCL system. Moreover, any computer that contains a device that is not on the HCL is not considered compliant. If a particular computer is on the HCL, it can contain any combination of devices listed on the HCL and still qualify for support, even though the system as a whole has not been tested.
Microsoft follows the following guidelines and troubleshooting steps for non-HCL equipment support issues.
Step 1: Hardware Configuration Inquiry
Step 2: TroubleshootingA standard troubleshooting process is used to isolate the cause of the problem. The following list includes some of the resources and techniques that the Microsoft Support Professional uses:
If there is no solution to the problem, the Support Professional explains the reason and recommends constructive alternatives, including one or more of the following:
Step 3: Other ResourcesPSS policy with regard to a Windows failure that is related to non-HCL hardware is as follows:
The Support Professional directs the customer to the following Knowledge Base article:
310064Alternatively, the Support Professional can provide information about the location of the same file or files and where they can be downloaded (Microsoft Web site, Microsoft FTP server, and Microsoft Download Library). If the customer decides to bypass Step 2 (does not want to be charged for an incident), the customer may try to resolve the issue without charge by using the previously mentioned troubleshooting documents.

Server Down or Data Loss IssuesThere is a possibility that by installing or upgrading to Windows XP on unsupported hardware, a customer may lose some operating system functionality or data. In cases where the previous operating system was a Microsoft operating system (such as Microsoft Windows 98, Microsoft Windows Millennium Edition [Me], Microsoft Windows NT 4.0, or Microsoft Windows 2000), the Support Professional determines whether the issue is a problem with the operating system or is related to a non-HCL hardware issue. If the problem is the operating system, the Support Professional files a report and evaluates the problem to provide a fix. The Support Professional also tries to recover the system.
If the problem is related to hardware incompatibility, the customer will need to restore the previous operating system and data from backup. If the customer does not have a backup of the previous operating system, the Support Professional will help the customer install only the previous working operating system. This does not include other drive file structures, data or security, or any other previous operating system settings.
In cases where the previous operating system is not a Microsoft operating system (for example, a PowerPC system with an AIX, Linux, or Macintosh operating system), Microsoft cannot help customers recover their systems. PSS Support Professionals are not responsible for performing recovery procedures on non-Microsoft operating systems.
