Ok, I didn't explain that very well. It's the seccond of two IDE controller cards, each with 2 channels. ide0 and ide1 are in use for normal system purposes. It's ide2 and ide3 I want to zap. I have tried hdx=none, and it disables the hard disk, but idex=noprobe does nothing with respect to ioports. Could it be the pci subsystem that's setting all this up? Is there some option sort of like pcix=noprobe?
