Hi greg and Igor. Maybe there are advantages to leaving your cdrom ide/atapi, but i just went ahead and changed both of mine. That meant i didn't even have ide/atapi cdrom support compiled in and I didn't have to question whether the ide/atapi driver was interfering with the scsi. But whether you use just scsi or use both, you still definitely do have to have scsi cdrom suport, as well as scsi, scsi emulation, and generic scsi enabled. From what you say in past posts, Igor, you may have thought you could leave scsi cdrom support out. I just think it's simpler not to have to deal with both drivers unless you have a really good reason for keeping the ide/atapi for your cdrom.
