If you have an IDE floppy drive which uses the ATAPI protocol,
answer Y. ATAPI is a newer protocol used by IDE CD-ROM/tape/floppy
drives, similar to the SCSI protocol.

The LS-120 and the IDE/ATAPI Iomega ZIP drive are also supported by
this driver. For information about jumper settings and the question
of when a ZIP drive uses a partition table, see
<http://www.win.tue.nl/~aeb/linux/zip/zip-1.html>.
(ATAPI PD-CD/CDR drives are not supported by this driver; support
for PD-CD/CDR drives is available if you answer Y to
"SCSI emulation support", below).

If you say Y here, the FLOPPY drive will be identified along with
other IDE devices, as "hdb" or "hdc", or something similar (check
the boot messages with dmesg).

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