|Enable UDMA66 Mode on Intel Chipsets (Windows 2000/XP)|
Category: Home > Hardware > Processor and Motherboard
If you have a computer with an Intel chipset that supports UDMA66, you will still find that UDMA66 mode is disabled by default on Windows 2000 computers. This tweak allows you to enable or disable it.
Open your registry and find the key below.
Create a new DWORD value called "EnableUDMA66" and set it to "1" to enable UDMA66 or "0" to disable it.
Restart Windows for the change to take effect.
Note: Before you enable UDMA66 mode make sure that the device supports UDMA66 mode and use an 80-pin IDE cable with the proper pin cut.
