A virtualized OS should not need to see the IDE controller in the host OS.
Are you trying to get a PCI IDE controller to work in Win7? If it doesn't work in Win7, then a virtualized OS won't be able to detect it either. Find the IDE controller's chipset manufacturer and check their site for drivers.
