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.
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.
Support for ATA/ATAPI disks (including ATAPI floppy drives). To compile this driver as a module, choose M here. The module will be called ide-gd_mod. If unsure, say Y.
This will include support for ATA hard disks. If unsure, say Y.
This will include support for ATAPI floppy drives (i.e. Iomega ZIP or MKE LS-120). 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>. If unsure, say N.
Support for Compact Flash cards, outboard IDE disks, tape drives, and CD-ROM drives connected through a PCMCIA card.
Support for Delkin, ASKA, and Workbit Cardbus CompactFlash Adapters. This may also work for similar SD and XD adapters.
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.
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.
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.
Implement ACPI support for generic IDE devices. On modern machines ACPI support is required to properly handle ACPI S3 states.
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.
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.
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.
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.
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>.
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.
If you have a PnP (Plug and Play) compatible EIDE card and would like the kernel to automatically detect and activate it, say Y here.
Probe IDE PCI devices in the order in which they appear on the PCI bus (i.e. 00:1f.1 PCI device before 02:01.0 PCI device) 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.
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.
This option provides generic support for various PCI IDE Chipsets which otherwise might not be supported.
This is a driver for the OPTi 82C621 EIDE controller. Please read the comments at the top of <file:drivers/ide/pci/opti621.c>.
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.

Include support for PIO tuning and virtual DMA on the Cyrix MediaGX 5510/5520 chipset. This will automatically be detected and configured if found. It is safe to say Y to this question.
Include support for UDMA on the Cyrix MediaGX 5530 chipset. This will automatically be detected and configured if found. It is safe to say Y to this question.
Include support for UDMA on the NSC/AMD CS5535 companion chipset. This will automatically be detected and configured if found. It is safe to say Y to this question.
This option enables support for the AMD CS5536 companion chip used with the Geode LX processor family. If unsure, say N.
HPT366 is an Ultra DMA chipset for ATA-66. HPT368 is an Ultra DMA chipset for ATA-66 RAID Based. HPT370 is an Ultra DMA chipset for ATA-100. HPT372 is an Ultra DMA chipset for ATA-100. HPT374 is an Ultra DMA chipset for ATA-100. This driver adds up to 4 more EIDE devices sharing a single interrupt. The HPT366 chipset in its current form is bootable. One solution for this problem are special LILO commands for redirecting the reference to device 0x80. The other solution is to say Y to "Boot off-board chipsets first support" (CONFIG_BLK_DEV_OFFBOARD) unless your mother board has the chipset natively mounted. Regardless one should use the fore mentioned option and call at LILO. This driver requires dynamic tuning of the chipset during the ide-probe at boot. It is reported to support DVD II drives, by the manufacturer.

Promise Ultra33 or PDC20246 Promise Ultra66 or PDC20262 Promise Ultra100 or PDC20265/PDC20267/PDC20268 This driver adds up to 4 more EIDE devices sharing a single interrupt. This add-on card is a bootable PCI UDMA controller. Since multiple cards can be installed and there are BIOS ROM problems that happen if the BIOS revisions of all installed cards (three-max) do not match, the driver attempts to do dynamic tuning of the chipset at boot-time for max-speed. Ultra33 BIOS 1.25 or newer is required for more than one card. Please read the comments at the top of <file:drivers/ide/pci/pdc202xx_old.c>. If unsure, say N.
This driver adds PIO/(U)DMA support for the ServerWorks OSB4/CSB5 chipsets.

If you have a Winbond SL82c105 IDE controller, say Y here to enable special configuration for this chip. This is common on various CHRP motherboards, but could be used elsewhere. If in doubt, say Y.
This driver ensures (U)DMA support for Victory66 SouthBridges for SMsC with Intel NorthBridges. This is an Ultra66 based chipset. The nice thing about it is that you can mix Ultra/DMA/PIO devices and it will handle timing cycles. Since this is an improved look-a-like to the PIIX4 it should be a nice addition. Please read the comments at the top of <file:drivers/ide/pci/slc90e66.c>.
This driver adds support for bus master DMA transfers using the Tekram TRM290 PCI IDE chip. Volunteers are needed for further tweaking and development. Please read the comments at the top of <file:drivers/ide/pci/trm290.c>.
This driver adds explicit support for VIA BusMastering IDE chips. This allows the kernel to change PIO, DMA and UDMA speeds and to configure the chip to optimum performance.
This driver adds support for Toshiba TC86C001 GOKU-S chip.
This driver provides support for the on-board IDE controller on Toshiba Cell Reference Board. If unsure, say Y.
This driver provides support for the on-board IDE controller on most of the recent Apple Power Macintoshes and PowerBooks. If unsure, say Y.
This option will cause the ATA/100 controller found in UniNorth2 based machines (Windtunnel PowerMac, Aluminium PowerBooks, ...) to be probed before the ATA/66 and ATA/33 controllers. Without these, those machine used to have the hard disk on hdc and the CD-ROM on hda. This option changes this to more natural hda for hard disk and hdc for CD-ROM.
On Acorn systems, say Y here if you wish to use the ICS IDE interface card. This is not required for ICS partition support. If you are unsure, say N to this.
Say Y here if you want to add DMA (Direct Memory Access) support to the ICS IDE driver.
Say Y here if you want to support the Yellowstone RapIDE controller manufactured for use with Acorn computers.
Enables the H8300 IDE driver.
This is the IDE driver for the Amiga Gayle IDE interface. It supports both the `A1200 style' and `A4000 style' of the Gayle IDE interface, This includes on-board IDE interfaces on some Amiga models (A600, A1200, A4000, and A4000T), and IDE interfaces on the Zorro expansion bus (M-Tech E-Matrix 530 expansion card). It also provides support for the so-called `IDE doublers' (made by various manufacturers, e.g. Eyetech) that can be connected to the on-board IDE interface of some Amiga models. Using such an IDE doubler, you can connect up to four instead of two IDE devices to the Amiga's on-board IDE interface. The feature is enabled at kernel runtime using the "gayle.doubler" kernel boot parameter. Say Y if you have an Amiga with a Gayle IDE interface and want to use IDE devices (hard disks, CD-ROM drives, etc.) that are connected to it. Note that you also have to enable Zorro bus support if you want to use Gayle IDE interfaces on the Zorro expansion bus.

It supports both the `Quadra style' (used in Quadra/ Centris 630 and Performa 588 models) and `Powerbook style' (used in the Powerbook 150 and 190 models) IDE interface. Say Y if you have such an Macintosh model and want to use IDE devices (hard disks, CD-ROM drives, etc.) that are connected to the on-board IDE interface.
Enable the on-board IDE controller in the Q40/Q60. This should normally be on; disable it only if you are running a custom hard drive subsystem through an expansion card.
Say Y here if you want to support the onchip IDE controller on the TI DaVinci SoC
Certain older chipsets, including the Tekram 690CD, use a single set of I/O ports at 0x1f0 to control up to four drives, instead of the customary two drives per port. Support for this can be enabled at runtime using the "ide-4drives.probe" kernel boot parameter if you say Y here.
This driver is enabled at runtime using the "ali14xx.probe" kernel boot parameter. It enables support for the secondary IDE interface of the ALI M1439/1443/1445/1487/1489 chipsets, and permits faster I/O speeds to be set as well.
