---help---
If you say Y here, your kernel will be able to manage ATA/(E)IDE and
ATAPI units. The most common cases are IDE hard drives and ATAPI
CD-ROM drives.
This subsystem is currently in maintenance mode with only bug fix
changes applied. Users of ATA hardware are encouraged to migrate to
the newer ATA subsystem ("Serial ATA (prod) and Parallel ATA
(experimental) drivers") which is more actively maintained.
To compile this driver as a module, choose M here: the
module will be called ide-core.
For further information, please read <file:Documentation/ide/ide.txt>.
If unsure, say N.

---help---
There are two drivers for Serial ATA controllers.
The main driver, "libata", uses the SCSI subsystem
and supports most modern SATA controllers. In order to use it
you may take a look at "Serial ATA (prod) and Parallel ATA
(experimental) drivers".
The IDE driver (which you are currently configuring) supports
a few first-generation SATA controllers.
In order to eliminate conflicts between the two subsystems,
this config option enables the IDE driver's SATA support.
Normally this is disabled, as it is preferred that libata
supports SATA controllers, and this (IDE) driver supports
PATA controllers.
If unsure, say N.

config BLK_DEV_IDECD
tristate "Include IDE/ATAPI CDROM support"
select IDE_ATAPI
---help---
If you have a CD-ROM drive using the ATAPI protocol, say Y. ATAPI is
a newer protocol used by IDE CD-ROM and TAPE drives, similar to the
SCSI protocol. Most new CD-ROM drives use ATAPI, including the
NEC-260, Mitsumi FX400, Sony 55E, and just about all non-SCSI
double(2X) or better speed drives.
If you say Y here, the CD-ROM drive will be identified at boot time
along with other IDE devices, as "hdb" or "hdc", or something
similar (check the boot messages with dmesg). If this is your only
CD-ROM drive, you can say N to all other CD-ROM options, but be sure
to say Y or M to "ISO 9660 CD-ROM file system support".
To compile this driver as a module, choose M here: the
module will be called ide-cd.

bool "Verbose error logging for IDE/ATAPI CDROM driver" if EXPERT
depends on BLK_DEV_IDECD
default y
help
Turn this on to have the driver print out the meanings of the
ATAPI error codes. This will use up additional 8kB of kernel-space
memory, though.
config BLK_DEV_IDETAPE
tristate "Include IDE/ATAPI TAPE support"
select IDE_ATAPI
help
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.
config BLK_DEV_IDEACPI

Implement ACPI support for generic IDE devices. On modern
machines ACPI support is required to properly handle ACPI S3 states.
config IDE_TASK_IOCTL

help
This is a direct raw access to the media. It is a complex but
elegant solution to test and validate the domain of the hardware and
perform below the driver data recovery if needed. This is the most
basic form of media-forensics.
If you are unsure, say N here.
config IDE_PROC_FS

depends on IDE && PROC_FS

help
This option enables support for the various files in
/proc/ide. In Linux 2.6 this has been superseded by
files in sysfs but many legacy applications rely on this.
If unsure say Y.
comment "IDE chipset support/bugfixes"
config IDE_GENERIC
tristate "generic/default IDE chipset support"
depends on ALPHA || X86 || IA64 || M32R || MIPS || ARCH_RPC
default ARM && ARCH_RPC
help
This is the generic IDE driver. This driver attaches to the
fixed legacy ports (e.g. on PCs 0x1f0/0x170, 0x1e8/0x168 and
so on). Please note that if this driver is built into the
kernel or loaded before other ATA (IDE or libata) drivers
and the controller is located at legacy ports, this driver
may grab those ports and thus can prevent the controller
specific driver from attaching.
Also, currently, IDE generic doesn't allow IRQ sharing
meaning that the IRQs it grabs won't be available to other
controllers sharing those IRQs which usually makes drivers
for those controllers fail. Generally, it's not a good idea
to load IDE generic driver on modern systems.
If unsure, say N.
config BLK_DEV_PLATFORM
tristate "Platform driver for IDE interfaces"
help
This is the platform IDE driver, used mostly for Memory Mapped
IDE devices, like Compact Flashes running in True IDE mode.
If unsure, say N.
config BLK_DEV_CMD640
tristate "CMD640 chipset bugfix/support"
depends on X86
select IDE_TIMINGS
---help---
The CMD-Technologies CMD640 IDE chip is used on many common 486 and
Pentium motherboards, usually in combination with a "Neptune" or
"SiS" chipset. Unfortunately, it has a number of rather nasty
design flaws that can cause severe data corruption under many common
conditions. Say Y here to include code which tries to automatically
detect and correct the problems under Linux. This option also
enables access to the secondary IDE ports in some CMD640 based
systems.
This driver will work automatically in PCI based systems (most new
systems have PCI slots). But if your system uses VESA local bus
(VLB) instead of PCI, you must also supply a kernel boot parameter
to enable the CMD640 bugfix/support: "cmd640.probe_vlb". (Try "man
bootparam" or see the documentation of your boot loader about how to
pass options to the kernel.)
The CMD640 chip is also used on add-in cards by Acculogic, and on
the "CSA-6400E PCI to IDE controller" that some people have. For
details, read <file:Documentation/ide/ide.txt>.
config BLK_DEV_CMD640_ENHANCED
bool "CMD640 enhanced support"

help
This option includes support for setting/autotuning PIO modes and
prefetch on CMD640 IDE interfaces. For details, read
<file:Documentation/ide/ide.txt>. If you have a CMD640 IDE interface
and your BIOS does not already do this for you, then say Y here.
Otherwise say N.

instead of the order in which IDE PCI host drivers are loaded.
Please note that this method of assuring stable naming of
IDE devices is unreliable and use other means for achieving
it (i.e. udev).
If in doubt, say N.

help
Normally, IDE controllers built into the motherboard (on-board
controllers) are assigned to ide0 and ide1 while those on add-in PCI
cards (off-board controllers) are relegated to ide2 and ide3.
Answering Y here will allow you to reverse the situation, with
off-board controllers on ide0/1 and on-board controllers on ide2/3.
This can improve the usability of some boot managers such as lilo
when booting from a drive on an off-board controller.
Note that, if you do this, the order of the hd* devices will be
rearranged which may require modification of fstab and other files.
Please also note that this method of assuring stable naming of
IDE devices is unreliable and use other means for achieving it
(i.e. udev).
If in doubt, say N.
config BLK_DEV_GENERIC
tristate "Generic PCI IDE Chipset Support"
select BLK_DEV_IDEPCI
help
This option provides generic support for various PCI IDE Chipsets
which otherwise might not be supported.
config BLK_DEV_OPTI621
tristate "OPTi 82C621 chipset enhanced support"
select BLK_DEV_IDEPCI
help
This is a driver for the OPTi 82C621 EIDE controller.
Please read the comments at the top of <file:drivers/ide/opti621.c>.
config BLK_DEV_RZ1000
tristate "RZ1000 chipset bugfix/support"
depends on X86
select BLK_DEV_IDEPCI
help
The PC-Technologies RZ1000 IDE chip is used on many common 486 and
Pentium motherboards, usually along with the "Neptune" chipset.
Unfortunately, it has a rather nasty design flaw that can cause
severe data corruption under many conditions. Say Y here to include
code which automatically detects and corrects the problem under
Linux. This may slow disk throughput by a few percent, but at least
things will operate 100% reliably.
config BLK_DEV_IDEDMA_PCI

select BLK_DEV_IDEPCI
select BLK_DEV_IDEDMA_SFF
config BLK_DEV_AEC62XX
tristate "AEC62XX chipset support"
select BLK_DEV_IDEDMA_PCI
help
This driver adds explicit support for Acard AEC62xx (Artop ATP8xx)
IDE controllers. This allows the kernel to change PIO, DMA and UDMA
speeds and to configure the chip to optimum performance.
config BLK_DEV_ALI15X3
tristate "ALI M15x3 chipset support"
select IDE_TIMINGS
select BLK_DEV_IDEDMA_PCI
help
This driver ensures (U)DMA support for ALI 1533, 1543 and 1543C
onboard chipsets. It also tests for Simplex mode and enables
normal dual channel support.
Please read the comments at the top of
<file:drivers/ide/alim15x3.c>.
If unsure, say N.
config BLK_DEV_AMD74XX
tristate "AMD and nVidia IDE support"
depends on !ARM
select IDE_TIMINGS
select BLK_DEV_IDEDMA_PCI
help
This driver adds explicit support for AMD-7xx and AMD-8111 chips
and also for the nVidia nForce chip. This allows the kernel to
change PIO, DMA and UDMA speeds and to configure the chip to
optimum performance.
config BLK_DEV_ATIIXP
