Multiple IDE Controllers

hornerj asks: "I was just reading the highlights on the 2.4 kernel and I see that Linux currently has support for more than 4 IDE devices. I have always been told that multiple controllers was a thing of the past and that finding a good controller was impossible. Where can I find more information on installing a second IDE controller, for my 5th, 6th, 7th, and 8th devices, and where can I find out which IDE controllers are supported? I haven't seen the HOWTO for multiple IDE controllers yet. Is there one? Thanks. "
