UltraDMA-66 IDE Controller
Common Options : Enabled, Disabled
Quick Review
This BIOS feature is only found in certain motherboards that come with an additional built-in IDE controller. It allows you to enable or disable the function of that IDE controller.
If you want to attach one or more IDE devices to the external UltraDMA/66 controller, you should enable this feature. You should only disable this BIOS feature for the following reasons :-
- if you do not have any IDE device attached to the external UltraDMA/66 controller
- for troubleshooting purposes
Disabling the external IDE controller will free up two IRQs which can be used by other devices in the system. It will also speed up the boot-up sequence because the external IDE controller's BIOS no longer needs to be loaded. Your system will also be able to skip the external controller's long boot-up check and initialization sequence.
Therefore, if you do not use the external IDE controller, it is recommended that you disable it for a much faster booting process.
