IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.
 
SUMMARY
The UDMA66 mode is disabled by default on a Windows computer with a Intel chipset that supports UDMA66. This is by design. The procedure in the "More Information" section explains how to enable it.
 
NOTE: Windows XP supports UDMA 100. Presently, two promise controllers for UDMA 100 are logged.
