	  "Symmetric Multi Processing" above, you should say Y here to read
	  and set the RTC in an SMP compatible fashion.

	  If you think you have a use for such a device (such as periodic data
	  sampling), then say Y here, and read <file:Documentation/rtc.txt>
	  for details.

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

	  major number 10 and minor number 135 using mknod ("man mknod"), you
	  will get access to the real time clock built into your computer.

config FTAPE
	tristate "Ftape (QIC-80/Travan) support"
	depends on BROKEN_ON_SMP && (ALPHA || X86)
	---help---
	  If you have a tape drive that is connected to your floppy
	  controller, say Y here.

	  Some tape drives (like the Seagate "Tape Store 3200" or the Iomega
	  "Ditto 3200" or the Exabyte "Eagle TR-3") come with a "high speed"
	  controller of their own. These drives (and their companion
	  controllers) are also supported if you say Y here.

	  If you have a special controller (such as the CMS FC-10, FC-20,
	  Mountain Mach-II, or any controller that is based on the Intel 82078
	  FDC like the high speed controllers by Seagate and Exabyte and
	  Iomega's "Ditto Dash") you must configure it by selecting the
	  appropriate entries from the "Floppy tape controllers" sub-menu
	  below and possibly modify the default values for the IRQ and DMA
	  channel and the IO base in ftape's configuration menu.

	  If you want to use your floppy tape drive on a PCI-bus based system,
	  please read the file <file:drivers/char/ftape/README.PCI>.

	  The ftape kernel driver is also available as a runtime loadable
	  module. To compile this driver as a module, choose M here: the
	  module will be called ftape.

	  Note that the Ftape-HOWTO is out of date (sorry) and documents the
	  older version 2.08 of this software but still contains useful
	  information.  There is a web page with more recent documentation at
	  <http://www.instmath.rwth-aachen.de/~heine/ftape/>.  This page
	  always contains the latest release of the ftape driver and useful
	  information (backup software, ftape related patches and
	  documentation, FAQ).  Note that the file system interface has
	  changed quite a bit compared to previous versions of ftape.  Please
	  read <file:Documentation/ftape.txt>.

	  The ACP modem (Mwave) for Linux is a WinModem. It is composed of a
	  kernel driver and a user level application. Together these components
	  support direct attachment to public switched telephone networks (PSTNs)
	  and support selected world wide countries.

	  This version of the ACP Modem driver supports the IBM Thinkpad 600E,
	  600, and 770 that include on board ACP modem hardware.

	  The modem also supports the standard communications port interface
	  (ttySx) and is compatible with the Hayes AT Command Set.

	  The user level application needed to use this driver can be found at
	  the IBM Linux Technology Center (LTC) web site:

	  See the raw(8) manpage for more details.

          The raw driver is deprecated and may be removed from 2.7
