Why do all of you talk so much nonsense

1. OS3.9 does *not* come with IDEfix. It uses an installed IDEfix but copying it removes the registration. Just enter your reg code again and it'll be registered again.
2. OS3.9 does *not* handle 4-way adapters on its own. If you have a 4-way adapter you *need* IDEfix.
"atapi.device" is a part of IDEfix and handles the 4-way adapter. Still you need to register or you will get nerve-requesters.
If you don't have a 4-way adapter, you no longer need IDEfix because OS3.9 comes with its own ATAPI driver so CD-ROM drives are recognised by the standard scsi.device.
