I don't know the truth, but I was told earlier by someone on the list
that it's all or nothing. Once you are using scsi support for the
CD-RW, you get it for the regular CD as well. That's the way I'm
running - /dev/sr0 for the writer and /dev/sr1 for the noraml cd. And
I have to have the parameter in lilo
append="hda=ide-scsi hdb=ide-scsi"
since my scsi support is built into the kernel.
