  3ware is the only hardware ATA-Raid product in Linux to date.
  This card is 2,4, or 8 channel master mode support only.
  SCSI support required!!!

  <http://www.3ware.com/>

  Please read the comments at the top of
  <file:drivers/scsi/3w-xxxx.c>.

AEC62XX chipset support
CONFIG_BLK_DEV_AEC62XX
  This driver adds up to 4 more EIDE devices sharing a single
  interrupt. This add-on card is a bootable PCI UDMA controller. In
  order to get this card to initialize correctly in some cases, you
  should say Y here, and preferably also to "Use DMA by default when
  available".

  The ATP850U/UF is an UltraDMA 33 chipset base.
  The ATP860 is an UltraDMA 66 chipset base.
  The ATP860M(acintosh) version is an UltraDMA 66 chipset base.

  Please read the comments at the top of <file:drivers/ide/aec62xx.c>.
  If you say Y here, then say Y to "Use DMA by default when available"
  as well.

AEC62XX Tuning support
CONFIG_AEC62XX_TUNING
  Please read the comments at the top of <file:drivers/ide/aec62xx.c>.
  If unsure, say N.

ALI M15x3 chipset support
CONFIG_BLK_DEV_ALI15X3
  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.

  If you say Y here, you also need to say Y to "Use DMA by default
  when available", above.  Please read the comments at the top of
  <file:drivers/ide/alim15x3.c>.

  If unsure, say N.

ALI M15x3 WDC support (DANGEROUS)
CONFIG_WDC_ALI15X3
  This allows for UltraDMA support for WDC drives that ignore CRC
  checking. You are a fool for enabling this option, but there have
  been requests. DO NOT COMPLAIN IF YOUR DRIVE HAS FS CORRUPTION, IF
  YOU ENABLE THIS! No one will listen, just laugh for ignoring this
  SERIOUS WARNING.

  Using this option can allow WDC drives to run at ATA-4/5 transfer
  rates with only an ATA-2 support structure.

  SAY N!

AMD Viper (7401/7409/7411) chipset support
CONFIG_BLK_DEV_AMD74XX
  This driver ensures (U)DMA support for the AMD756/760 Viper
  chipsets.

  If you say Y here, you also need to say Y to "Use DMA by default
  when available", above.
  Please read the comments at the top of <file:drivers/ide/amd74xx.c>.

  If unsure, say N.

AMD Viper ATA-66 Override support (WIP)
CONFIG_AMD74XX_OVERRIDE
  This option auto-forces the ata66 flag.
  This effect can be also invoked by calling "idex=ata66"
  If unsure, say N.

CMD64X chipset support
CONFIG_BLK_DEV_CMD64X
  Say Y here if you have an IDE controller which uses any of these
  chipsets: CMD643, CMD646, or CMD648.

CY82C693 chipset support
CONFIG_BLK_DEV_CY82C693
  This driver adds detection and support for the CY82C693 chipset
  used on Digital's PC-Alpha 164SX boards.

  If you say Y here, you need to say Y to "Use DMA by default
  when available" as well.

Cyrix CS5530 MediaGX chipset support
CONFIG_BLK_DEV_CS5530
  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.

  People with SCSI-only systems should say N here. If unsure, say Y.

HPT34X chipset support
CONFIG_BLK_DEV_HPT34X
  This driver adds up to 4 more EIDE devices sharing a single
  interrupt. The HPT343 chipset in its current form is a non-bootable
  controller; the HPT345/HPT363 chipset is a bootable (needs BIOS FIX)
  PCI UDMA controllers. This driver requires dynamic tuning of the
  chipset during the ide-probe at boot time. It is reported to support
  DVD II drives, by the manufacturer.

HPT34X AUTODMA support (WIP)
CONFIG_HPT34X_AUTODMA
  This is a dangerous thing to attempt currently! Please read the
  comments at the top of <file:drivers/ide/hpt34x.c>.  If you say Y
  here, then say Y to "Use DMA by default when available" as well.

  If unsure, say N.

HPT366 chipset support
CONFIG_BLK_DEV_HPT366
  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.

  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 or include
  "ide=reverse" in LILO's append-line.

  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.

NS87415 chipset support (EXPERIMENTAL)
CONFIG_BLK_DEV_NS87415
  This driver adds detection and support for the NS87415 chip
  (used in SPARC64, among others).

  Please read the comments at the top of <file:drivers/ide/ns87415.c>.

OPTi 82C621 chipset enhanced support (EXPERIMENTAL)
CONFIG_BLK_DEV_OPTI621
  This is a driver for the OPTi 82C621 EIDE controller.
  Please read the comments at the top of <file:drivers/ide/opti621.c>.

ServerWorks OSB4/CSB5 chipset support
CONFIG_BLK_DEV_SVWKS
  This driver adds PIO/(U)DMA support for the ServerWorks OSB4/CSB5
  chipsets.

Intel PIIXn chipsets support
CONFIG_BLK_DEV_PIIX
  This driver adds PIO mode setting and tuning for all PIIX IDE
  controllers by Intel.  Since the BIOS can sometimes improperly tune
  PIO 0-4 mode settings, this allows dynamic tuning of the chipset
  via the standard end-user tool 'hdparm'.

  Please read the comments at the top of <file:drivers/ide/piix.c>.

  If you say Y here, you should also say Y to "PIIXn Tuning support",
  below.

  If unsure, say N.

PIIXn Tuning support
CONFIG_PIIX_TUNING
  This driver extension adds DMA mode setting and tuning for all PIIX
  IDE controllers by Intel. Since the BIOS can sometimes improperly
  set up the device/adapter combination and speed limits, it has
  become a necessity to back/forward speed devices as needed.

  Case 430HX/440FX PIIX3 need speed limits to reduce UDMA to DMA mode
  2 if the BIOS can not perform this task at initialization.

  If unsure, say N.

PROMISE PDC20246/PDC20262/PDC20265/PDC20267/PDC20268 support
CONFIG_BLK_DEV_PDC202XX
  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. This card may require that you say Y to
  "Special UDMA Feature".

  If you say Y here, you need to say Y to "Use DMA by default when
  available" as well.

  Please read the comments at the top of
  <file:drivers/ide/pdc202xx.c>.

  If unsure, say N.

Special UDMA Feature
CONFIG_PDC202XX_BURST
  This option causes the pdc202xx driver to enable UDMA modes on the
  PDC202xx even when the PDC202xx BIOS has not done so.

  It was originally designed for the PDC20246/Ultra33, whose BIOS will
  only setup UDMA on the first two PDC20246 cards.  It has also been
  used succesfully on a PDC20265/Ultra100, allowing use of UDMA modes
  when the PDC20265 BIOS has been disabled (for faster boot up).

  Please read the comments at the top of
  <file:drivers/ide/pdc202xx.c>.

  If unsure, say N.

Special FastTrak Feature
CONFIG_PDC202XX_FORCE
  For FastTrak enable overriding BIOS.

SiS5513 chipset support
CONFIG_BLK_DEV_SIS5513
  This driver ensures (U)DMA support for SIS5513 chipset based
  mainboards. SiS620/530 UDMA mode 4, SiS5600/5597 UDMA mode 2, all
  other DMA mode 2 limited chipsets are unsupported to date.

  If you say Y here, you need to say Y to "Use DMA by default when
  available" as well.

  Please read the comments at the top of <file:drivers/ide/sis5513.c>.

SLC90E66 chipset support
CONFIG_BLK_DEV_SLC90E66
  This driver ensures (U)DMA support for Victroy66 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.

  If you say Y here, you need to say Y to "Use DMA by default when
  available" as well.

  Please read the comments at the top of
  <file:drivers/ide/slc90e66.c>.

Winbond SL82c105 support
CONFIG_BLK_DEV_SL82C105
  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.

Tekram TRM290 chipset support
CONFIG_BLK_DEV_TRM290
  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/trm290.c>.

VIA82CXXX chipset support
CONFIG_BLK_DEV_VIA82CXXX
  This allows you to configure your chipset for a better use while
  running PIO/(U)DMA, it will allow you to enable efficiently the
  second channel dma usage, as it may not be set by BIOS.  It will try
  to set fifo configuration at its best.  It will allow you to get
  information from /proc/ide/via provided you enabled "/proc file
  system" support.

  Please read the comments at the top of
  <file:drivers/ide/via82cxxx.c>.

  If you say Y here, then say Y to "Use DMA by default when available"
  as well.

  If unsure, say N.

RapIDE interface support
CONFIG_BLK_DEV_IDE_RAPIDE
  Say Y here if you want to support the Yellowstone RapIDE controller
  manufactured for use with Acorn computers.

Other IDE chipset support
CONFIG_IDE_CHIPSETS
  Say Y here if you want to include enhanced support for various IDE
  interface chipsets used on motherboards and add-on cards. You can
  then pick your particular IDE chip from among the following options.
  This enhanced support may be necessary for Linux to be able to
  access the 3rd/4th drives in some systems. It may also enable
  setting of higher speed I/O rates to improve system performance with
  these chipsets. Most of these also require special kernel boot
  parameters to actually turn on the support at runtime; you can find
  a list of these in the file <file:Documentation/ide.txt>.
