└─>Include IDE/ATAPI TAPE support
In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
If you have an IDE tape drive using the ATAPI protocol, say Y.
ATAPI is a newer protocol used by IDE tape and CD-ROM drives,
similar to the SCSI protocol. If you have an SCSI tape drive
however, you can say N here.

You should also say Y if you have an OnStream DI-30 tape drive; this
will not work with the SCSI protocol, until there is support for the
SC-30 and SC-50 versions.

If you say Y here, the tape drive will be identified at boot time
along with other IDE devices, as "hdb" or "hdc", or something
similar, and will be mapped to a character device such as "ht0"
(check the boot messages with dmesg). Be sure to consult the
<file:drivers/ide/ide-tape.c> and <file:Documentation/ide/ide.txt>
files for usage information.

To compile this driver as a module, choose M here: the
module will be called ide-tape.
