Standard Dual Channel PCI IDE Controller
A PCI/IDE controller covers all devices that have a PCI or IDE connections. Normally CD DVD FLOPPIES HDD have a IDE connection. PCI usually your Modem, some grapics have this type of connection.
By removing the controller it will reinstall and reorganize the priority list in your Operation system for all devices with PCI/IDE connections.
Make sure that when you right click on the PCI/IDE bus master controller that it also removes the driver for your DVD/CD rom drive in the CD/DVD catagory in Device manager.
SCRU you aren't listing duplicates like ILL is showing.
Ill your computer is just confused which route to take because of the duplicate drivers.
Right click on all of your PCI IDE Bus Master controller. Leave the ATA channels alone. Do not remove those.
Restart your system and allow the computer to reinstall the components.
Let me know if I can answer any questions.
