#
#config ADK_KPACKAGE_KMOD_BLK_DEV_IDE
#	prompt "kmod-ide.......................... IDE support"
#	tristate
#	select ADK_KERNEL_BLOCK
#	select ADK_KERNEL_IDE
#	default n
#	help
#	  If you say Y here, you will use the full-featured IDE driver to
#	  control up to ten ATA/IDE interfaces, each being able to serve a
#	  "master" and a "slave" device, for a total of up to twenty ATA/IDE
#	  disk/cdrom/tape/floppy drives.
#
#	  Useful information about large (>540 MB) IDE disks, multiple
#	  interfaces, what to do if ATA/IDE devices are not automatically
#	  detected, sound card ATA/IDE ports, module support, and other
#	  topics, is contained in <file:Documentation/ide.txt>. For detailed
#	  information about hard drives, consult the Disk-HOWTO and the
#	  Multi-Disk-HOWTO, available from
#	  <http://www.tldp.org/docs.html#howto>.
#
#	  To fine-tune ATA/IDE drive/interface parameters for improved
#	  performance, look for the hdparm package at
#	  <ftp://ibiblio.org/pub/Linux/system/hardware/>.
#
#	  To compile this driver as a module, choose M here and read
#	  <file:Documentation/ide.txt>. The module will be called ide-mod.
#	  Do not compile this driver as a module if your root file system (the
#	  one containing the directory /) is located on an IDE device.

config ADK_KPACKAGE_KMOD_BLK_DEV_LOOP
	prompt "kmod-loop......................... Loop mount support"
	tristate
	default n
	help
	  Saying Y here will allow you to use a regular file as a block
	  device; you can then create a file system on that block device and
	  mount it just as you would mount other block devices such as hard
	  drive partitions, CD-ROM drives or floppy drives. The loop devices
	  are block special device files with major number 7 and typically
	  called /dev/loop0, /dev/loop1 etc.

	  This is useful if you want to check an ISO 9660 file system before
	  burning the CD, or if you want to use floppy images without first
	  writing them to floppy. Furthermore, some Linux distributions avoid
	  the need for a dedicated Linux partition by keeping their complete
	  root file system inside a DOS FAT file using this loop device
	  driver.

	  To use the loop device, you need the losetup utility, found in the
	  util-linux package, see
	  <ftp://ftp.kernel.org/pub/linux/utils/util-linux/>.

	  The loop device driver can also be used to "hide" a file system in
	  a disk partition, floppy, or regular file, either using encryption
	  (scrambling the data) or steganography (hiding the data in the low
	  bits of, say, a sound file). This is also safe if the file resides
	  on a remote file server.

	  There are several ways of encrypting disks. Some of these require
	  kernel patches. The vanilla kernel offers the cryptoloop option
	  and a Device Mapper target (which is superior, as it supports all
	  file systems). If you want to use the cryptoloop, say Y to both
	  LOOP and CRYPTOLOOP, and make sure you have a recent (version 2.12
	  or later) version of util-linux. Additionally, be aware that
	  the cryptoloop is not safe for storing journaled filesystems.

	  Note that this loop device has nothing to do with the loopback
	  device used for network connections from the machine to itself.

config ADK_KPACKAGE_KMOD_BLK_DEV_NBD
	prompt "kmod-nbd.......................... Network Block Device"
	tristate
	default n
	help
	  Saying Y here will allow your computer to be a client for network
	  block devices, i.e. it will be able to use block devices exported by
	  servers (mount file systems on them etc.). Communication between
	  client and server works over TCP/IP networking, but to the client
	  program this is hidden: it looks like a regular local file access to
	  a block device special file such as /dev/nd0.

	  Network block devices also allows you to run a block-device in
	  userland (making server and client physically the same computer,
	  communicating using the loopback network device).

	  Read <file:Documentation/nbd.txt> for more information, especially
	  about where to find the server code, which runs in user space and
	  does not need special kernel support.

	  Note that this has nothing to do with the network file systems NFS
	  or Coda; you can say N here even if you intend to use NFS or Coda.

config ADK_KPACKAGE_KMOD_SCSI
	prompt "kmod-scsi......................... SCSI support"
	select ADK_KERNEL_LBD
	select ADK_KERNEL_LSF

	depends on !ADK_KERNEL_SCSI
	tristate
	help
	  If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
	  any other SCSI device under Linux, say Y and make sure that you know
	  the name of your SCSI host adapter (the card inside your computer
	  that "speaks" the SCSI protocol, also called SCSI controller),
	  because you will be asked for it.

	  You also need to say Y here if you have a device which speaks
	  the SCSI protocol.  Examples of this include the parallel port
	  version of the IOMEGA ZIP drive, USB storage devices, Fibre
	  Channel, FireWire storage and the IDE-SCSI emulation driver.

config ADK_KPACKAGE_KMOD_BLK_DEV_SD
	prompt "kmod-scsi-disk.................... SCSI disk support"
	depends !ADK_KERNEL_SCSI
	depends ADK_KPACKAGE_KMOD_SCSI
	tristate
	help
	  If you want to use SCSI hard disks, Fibre Channel disks,
	  USB storage or the SCSI or parallel port version of
	  the IOMEGA ZIP drive, say Y and read the SCSI-HOWTO,
	  the Disk-HOWTO and the Multi-Disk-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>. This is NOT for SCSI
	  CD-ROMs.

config ADK_KPACKAGE_KMOD_BLK_DEV_SR
	prompt "kmod-scsi-cdrom................... SCSI CDROM support"
	depends !ADK_KERNEL_SCSI
	depends ADK_KPACKAGE_KMOD_SCSI
	tristate
	help
	  If you want to use a SCSI or FireWire CD-ROM under Linux,
	  say Y and read the SCSI-HOWTO and the CDROM-HOWTO at
	  <http://www.tldp.org/docs.html#howto>. Also make sure to say
	  Y or M to "ISO 9660 CD-ROM file system support" later.

	tristate
	help
	  Device-mapper is a low level volume manager.  It works by allowing
	  people to specify mappings for ranges of logical sectors.  Various
	  mapping types are available, in addition people may write their own
	  modules containing custom mappings if they wish.

	  Higher level volume managers such as LVM2 use this driver.

config ADK_KPACKAGE_KMOD_DM_CRYPT

	select ADK_KPACKAGE_KMOD_CRYPTO_CBC
	select ADK_KPACKAGE_KMOD_CRYPTO_BLKCIPHER
	tristate
	help
	  This device-mapper target allows you to create a device that
	  transparently encrypts the data on it. You'll need to activate
	  the ciphers you're going to use in the cryptoapi configuration.

	  Information on how to use dm-crypt can be found on

	  <http://www.saout.de/misc/dm-crypt/>

config ADK_KPACKAGE_KMOD_DM_SNAPSHOT

config ADK_KPACKAGE_KMOD_DM_MIRROR
	prompt "kmod-dm-mirror.................. Mirror target"
	depends on ADK_KPACKAGE_KMOD_BLK_DEV_DM
	tristate
	help
         Allow volume managers to mirror logical volumes, also
         needed for live data migration tools such as 'pvmove'.
