Do you have a link to what you gave bought?
How are you going to connect it to your A1200, do you have an ide splitter or fastata or something else?
If it's an internal cdrom some are hard wired master so you might have to hook it up to the second channel of a 4 way ide adapter.
You can use idefix97 to get it up and running. Unless you have a fastata, eide then you should use the elbox drivers.
