           ATAPI driver.
 
-          This is useful if you have an ATAPI device for which no native
-          driver has been written (for example, an ATAPI PD-CD drive);
-          you can then use this emulation together with an appropriate SCSI
-          device driver. In order to do this, say Y here and to "SCSI support"
-          and "SCSI generic support", below. You must then provide the kernel
-          command line "hdx=ide-scsi" (try "man bootparam" or see the
-          documentation of your boot loader (lilo or loadlin) about how to
-          pass options to the kernel at boot time) for devices if you want the
-          native EIDE sub-drivers to skip over the native support, so that
-          this SCSI emulation can be used instead.
-
-          Note that this option does NOT allow you to attach SCSI devices to a
-          box that doesn't have a SCSI host adapter installed.
-
           If both this SCSI emulation and native ATAPI support are compiled
           into the kernel, the native support will be used.
