Missing Microsoft Default Driver

[[H]ea\/y B]

I have an eVGA 680i Motherboard and an Intel SSD drive. Unfortunately the 680i doesn't support AHCI, so I can't use TRIM or the SSD Toolbox. I fixed this before by dropping the nVidia SATA drivers and using the MS Standard Dual Channel PCI IDE Controller driver. But I can't find that driver in my new Win 7 install. Anyone have any suggestions? I have looked everywhere for it, the DVD, the INF folder, anywhere I can think of. I really need this driver so I can use my SSD TRIM functions so the drive doesn't get hosed by Windows.
