14 If you say Y here, your kernel will be able to manage low cost mass
15 storage units such as ATA/(E)IDE and ATAPI units. The most common
16 cases are IDE hard drives and ATAPI CD-ROM drives.
18 If your system is pure SCSI and doesn't use these interfaces, you
21 Integrated Disk Electronics (IDE aka ATA-1) is a connecting standard
22 for mass storage units such as hard disks. It was designed by
23 Western Digital and Compaq Computer in 1984. It was then named
24 ST506. Quite a number of disks use the IDE interface.
26 AT Attachment (ATA) is the superset of the IDE specifications.
27 ST506 was also called ATA-1.
29 Fast-IDE is ATA-2 (also named Fast ATA), Enhanced IDE (EIDE) is
30 ATA-3. It provides support for larger disks (up to 8.4GB by means of
31 the LBA standard), more disks (4 instead of 2) and for other mass
32 storage units such as tapes and cdrom. UDMA/33 (aka UltraDMA/33) is
33 ATA-4 and provides faster (and more CPU friendly) transfer modes
34 than previous PIO (Programmed processor Input/Output) from previous
35 ATA/IDE standards by means of fast DMA controllers.
37 ATA Packet Interface (ATAPI) is a protocol used by EIDE tape and
38 CD-ROM drives, similar in many respects to the SCSI protocol.
40 SMART IDE (Self Monitoring, Analysis and Reporting Technology) was
41 designed in order to prevent data corruption and disk crash by
42 detecting pre hardware failure conditions (heat, access time, and
43 the like...). Disks built since June 1995 may follow this standard.
44 The kernel itself doesn't manage this; however there are quite a
45 number of user programs such as smart that can query the status of
46 SMART parameters from disk drives.
48 To compile this driver as a module, choose M here: the
49 module will be called ide.
51 For further information, please read <file:Documentation/ide.txt>.
58 int "Max IDE interfaces"
59 depends on ALPHA || SUPERH || IA64 || EMBEDDED
62 This is the maximum number of IDE hardware interfaces that will
63 be supported by the driver. Make sure it is at least as high as
64 the number of IDE interfaces in your system.
67 tristate "Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support"
69 If you say Y here, you will use the full-featured IDE driver to
70 control up to ten ATA/IDE interfaces, each being able to serve a
71 "master" and a "slave" device, for a total of up to twenty ATA/IDE
72 disk/cdrom/tape/floppy drives.
74 Useful information about large (>540 MB) IDE disks, multiple
75 interfaces, what to do if ATA/IDE devices are not automatically
76 detected, sound card ATA/IDE ports, module support, and other
77 topics, is contained in <file:Documentation/ide.txt>. For detailed
78 information about hard drives, consult the Disk-HOWTO and the
79 Multi-Disk-HOWTO, available from
80 <http://www.tldp.org/docs.html#howto>.
82 To fine-tune ATA/IDE drive/interface parameters for improved
83 performance, look for the hdparm package at
84 <ftp://ibiblio.org/pub/Linux/system/hardware/>.
86 To compile this driver as a module, choose M here and read
87 <file:Documentation/ide.txt>. The module will be called ide-mod.
88 Do not compile this driver as a module if your root file system (the
89 one containing the directory /) is located on an IDE device.
91 If you have one or more IDE drives, say Y or M here. If your system
92 has no IDE drives, or if memory requirements are really tight, you
93 could say N here, and select the "Old hard disk driver" below
94 instead to save about 13 KB of memory in the kernel.

100 config BLK_DEV_IDE_SATA
101 bool "Support for SATA (deprecated; conflicts with libata SATA driver)"
104 There are two drivers for Serial ATA controllers.
106 The main driver, "libata", exists inside the SCSI subsystem
107 and supports most modern SATA controllers.
109 The IDE driver (which you are currently configuring) supports
110 a few first-generation SATA controllers.
112 In order to eliminate conflicts between the two subsystems,
113 this config option enables the IDE driver's SATA support.
114 Normally this is disabled, as it is preferred that libata
115 supports SATA controllers, and this (IDE) driver supports
120 config BLK_DEV_HD_IDE
121 bool "Use old disk-only driver on primary interface"
122 depends on (X86 || SH_MPC1211)
124 There are two drivers for MFM/RLL/IDE disks. Most people use just
125 the new enhanced driver by itself. This option however installs the
126 old hard disk driver to control the primary IDE/disk interface in
127 the system, leaving the new enhanced IDE driver to take care of only
128 the 2nd/3rd/4th IDE interfaces. Doing this will prevent you from
129 having an IDE/ATAPI CD-ROM or tape drive connected to the primary
130 IDE interface. Choosing this option may be useful for older systems
131 which have MFM/RLL/ESDI controller+drives at the primary port
132 address (0x1f0), along with IDE drives at the secondary/3rd/4th port
135 Normally, just say N here; you will then use the new driver for all
138 config BLK_DEV_IDEDISK
139 tristate "Include IDE/ATA-2 DISK support"
141 This will include enhanced support for MFM/RLL/IDE hard disks. If
142 you have a MFM/RLL/IDE disk, and there is no special reason to use
143 the old hard disk driver instead, say Y. If you have an SCSI-only
144 system, you can say N here.
146 To compile this driver as a module, choose M here: the
147 module will be called ide-disk.
148 Do not compile this driver as a module if your root file system
149 (the one containing the directory /) is located on the IDE disk.
153 config IDEDISK_MULTI_MODE
154 bool "Use multi-mode by default"
156 If you get this error, try to say Y here:
158 hda: set_multmode: status=0x51 { DriveReady SeekComplete Error }
159 hda: set_multmode: error=0x04 { DriveStatusError }
164 tristate "PCMCIA IDE support"
167 Support for Compact Flash cards, outboard IDE disks, tape drives,
168 and CD-ROM drives connected through a PCMCIA card.
170 config BLK_DEV_DELKIN
171 tristate "Cardbus IDE support (Delkin/ASKA/Workbit)"
172 depends on CARDBUS && PCI
174 Support for Delkin, ASKA, and Workbit Cardbus CompactFlash
175 Adapters. This may also work for similar SD and XD adapters.
178 tristate "Include IDE/ATAPI CDROM support"
180 If you have a CD-ROM drive using the ATAPI protocol, say Y. ATAPI is
181 a newer protocol used by IDE CD-ROM and TAPE drives, similar to the
182 SCSI protocol. Most new CD-ROM drives use ATAPI, including the
183 NEC-260, Mitsumi FX400, Sony 55E, and just about all non-SCSI
184 double(2X) or better speed drives.
186 If you say Y here, the CD-ROM drive will be identified at boot time
187 along with other IDE devices, as "hdb" or "hdc", or something
188 similar (check the boot messages with dmesg). If this is your only
189 CD-ROM drive, you can say N to all other CD-ROM options, but be sure
190 to say Y or M to "ISO 9660 CD-ROM file system support".
192 Note that older versions of LILO (LInux LOader) cannot properly deal
193 with IDE/ATAPI CD-ROMs, so install LILO 16 or higher, available from
194 <http://lilo.go.dyndns.org/>.
196 To compile this driver as a module, choose M here: the
197 module will be called ide-cd.
199 config BLK_DEV_IDETAPE
200 tristate "Include IDE/ATAPI TAPE support (EXPERIMENTAL)"
201 depends on EXPERIMENTAL
203 If you have an IDE tape drive using the ATAPI protocol, say Y.
204 ATAPI is a newer protocol used by IDE tape and CD-ROM drives,
205 similar to the SCSI protocol. If you have an SCSI tape drive
206 however, you can say N here.
208 You should also say Y if you have an OnStream DI-30 tape drive; this
209 will not work with the SCSI protocol, until there is support for the
210 SC-30 and SC-50 versions.
212 If you say Y here, the tape drive will be identified at boot time
213 along with other IDE devices, as "hdb" or "hdc", or something
214 similar, and will be mapped to a character device such as "ht0"
215 (check the boot messages with dmesg). Be sure to consult the
216 <file:drivers/ide/ide-tape.c> and <file:Documentation/ide.txt> files
217 for usage information.
219 To compile this driver as a module, choose M here: the
220 module will be called ide-tape.
222 config BLK_DEV_IDEFLOPPY
223 tristate "Include IDE/ATAPI FLOPPY support"
225 If you have an IDE floppy drive which uses the ATAPI protocol,
226 answer Y. ATAPI is a newer protocol used by IDE CD-ROM/tape/floppy
227 drives, similar to the SCSI protocol.
229 The LS-120 and the IDE/ATAPI Iomega ZIP drive are also supported by
230 this driver. For information about jumper settings and the question
231 of when a ZIP drive uses a partition table, see
232 <http://www.win.tue.nl/~aeb/linux/zip/zip-1.html>.
233 (ATAPI PD-CD/CDR drives are not supported by this driver; support
234 for PD-CD/CDR drives is available if you answer Y to
235 "SCSI emulation support", below).
237 If you say Y here, the FLOPPY drive will be identified along with
238 other IDE devices, as "hdb" or "hdc", or something similar (check
239 the boot messages with dmesg).
241 To compile this driver as a module, choose M here: the
242 module will be called ide-floppy.
244 config BLK_DEV_IDESCSI
245 tristate "SCSI emulation support"
248 WARNING: ide-scsi is no longer needed for cd writing applications!
249 The 2.6 kernel supports direct writing to ide-cd, which eliminates
250 the need for ide-scsi + the entire scsi stack just for writing a
251 cd. The new method is more efficient in every way.
253 This will provide SCSI host adapter emulation for IDE ATAPI devices,
254 and will allow you to use a SCSI device driver instead of a native
257 This is useful if you have an ATAPI device for which no native
258 driver has been written (for example, an ATAPI PD-CD drive);
259 you can then use this emulation together with an appropriate SCSI
260 device driver. In order to do this, say Y here and to "SCSI support"
261 and "SCSI generic support", below. You must then provide the kernel
262 command line "hdx=ide-scsi" (try "man bootparam" or see the
263 documentation of your boot loader (lilo or loadlin) about how to
264 pass options to the kernel at boot time) for devices if you want the
265 native EIDE sub-drivers to skip over the native support, so that
266 this SCSI emulation can be used instead.
268 Note that this option does NOT allow you to attach SCSI devices to a
269 box that doesn't have a SCSI host adapter installed.
271 If both this SCSI emulation and native ATAPI support are compiled
272 into the kernel, the native support will be used.
274 config BLK_DEV_IDEACPI
275 bool "IDE ACPI support"
278 Implement ACPI support for generic IDE devices. On modern
279 machines ACPI support is required to properly handle ACPI S3 states.
281 config IDE_TASK_IOCTL
282 bool "IDE Taskfile Access"
284 This is a direct raw access to the media. It is a complex but
285 elegant solution to test and validate the domain of the hardware and
286 perform below the driver data recovery if needed. This is the most
287 basic form of media-forensics.
289 If you are unsure, say N here.
291 comment "IDE chipset support/bugfixes"
294 tristate "generic/default IDE chipset support"
299 config BLK_DEV_CMD640
300 bool "CMD640 chipset bugfix/support"
303 The CMD-Technologies CMD640 IDE chip is used on many common 486 and
304 Pentium motherboards, usually in combination with a "Neptune" or
305 "SiS" chipset. Unfortunately, it has a number of rather nasty
306 design flaws that can cause severe data corruption under many common
307 conditions. Say Y here to include code which tries to automatically
308 detect and correct the problems under Linux. This option also
309 enables access to the secondary IDE ports in some CMD640 based
312 This driver will work automatically in PCI based systems (most new
313 systems have PCI slots). But if your system uses VESA local bus
314 (VLB) instead of PCI, you must also supply a kernel boot parameter
315 to enable the CMD640 bugfix/support: "ide0=cmd640_vlb". (Try "man
316 bootparam" or see the documentation of your boot loader about how to
317 pass options to the kernel.)
319 The CMD640 chip is also used on add-in cards by Acculogic, and on
320 the "CSA-6400E PCI to IDE controller" that some people have. For
321 details, read <file:Documentation/ide.txt>.
323 config BLK_DEV_CMD640_ENHANCED
324 bool "CMD640 enhanced support"
325 depends on BLK_DEV_CMD640
327 This option includes support for setting/autotuning PIO modes and
328 prefetch on CMD640 IDE interfaces. For details, read
329 <file:Documentation/ide.txt>. If you have a CMD640 IDE interface
330 and your BIOS does not already do this for you, then say Y here.
333 config BLK_DEV_IDEPNP
334 bool "PNP EIDE support"
337 If you have a PnP (Plug and Play) compatible EIDE card and
338 would like the kernel to automatically detect and activate
341 config BLK_DEV_IDEPCI
342 bool "PCI IDE chipset support" if PCI
343 default BLK_DEV_IDEDMA_PMAC if PPC_PMAC && BLK_DEV_IDEDMA_PMAC
345 Say Y here for PCI systems which use IDE drive(s).
346 This option helps the IDE driver to automatically detect and
347 configure all PCI-based IDE interfaces in your system.
349 config IDEPCI_SHARE_IRQ
350 bool "Sharing PCI IDE interrupts support"
351 depends on PCI && BLK_DEV_IDEPCI
353 Some ATA/IDE chipsets have hardware support which allows for
354 sharing a single IRQ with other cards. To enable support for
355 this in the ATA/IDE driver, say Y here.
357 It is safe to say Y to this question, in most cases.
360 config BLK_DEV_OFFBOARD
361 bool "Boot off-board chipsets first support"
362 depends on PCI && BLK_DEV_IDEPCI
364 Normally, IDE controllers built into the motherboard (on-board
365 controllers) are assigned to ide0 and ide1 while those on add-in PCI
366 cards (off-board controllers) are relegated to ide2 and ide3.
367 Answering Y here will allow you to reverse the situation, with
368 off-board controllers on ide0/1 and on-board controllers on ide2/3.
369 This can improve the usability of some boot managers such as lilo
370 when booting from a drive on an off-board controller.
372 If you say Y here, and you actually want to reverse the device scan
373 order as explained above, you also need to issue the kernel command
374 line option "ide=reverse". (Try "man bootparam" or see the
375 documentation of your boot loader (lilo or loadlin) about how to
376 pass options to the kernel at boot time.)
378 Note that, if you do this, the order of the hd* devices will be
379 rearranged which may require modification of fstab and other files.

384 tristate "Generic PCI IDE Chipset Support"
385 depends on BLK_DEV_IDEPCI
387 This option provides generic support for various PCI IDE Chipsets
388 which otherwise might not be supported.

401 The PC-Technologies RZ1000 IDE chip is used on many common 486 and
402 Pentium motherboards, usually along with the "Neptune" chipset.
403 Unfortunately, it has a rather nasty design flaw that can cause
404 severe data corruption under many conditions. Say Y here to include
405 code which automatically detects and corrects the problem under
406 Linux. This may slow disk throughput by a few percent, but at least
407 things will operate 100% reliably.
409 config BLK_DEV_IDEDMA_PCI
410 bool "Generic PCI bus-master DMA support"
411 depends on PCI && BLK_DEV_IDEPCI
413 If your PCI system uses IDE drive(s) (as opposed to SCSI, say) and
414 is capable of bus-master DMA operation (most Pentium PCI systems),
415 you will want to say Y here to reduce CPU overhead. You can then use
416 the "hdparm" utility to enable DMA for drives for which it was not
417 enabled automatically. By default, DMA is not enabled automatically
418 for these drives, but you can change that by saying Y to the
419 following question "Use DMA by default when available". You can get
420 the latest version of the hdparm utility from
421 <ftp://ibiblio.org/pub/Linux/system/hardware/>.
423 Read the comments at the beginning of <file:drivers/ide/ide-dma.c>

453 tristate "ALI M15x3 chipset support"
455 This driver ensures (U)DMA support for ALI 1533, 1543 and 1543C
456 onboard chipsets. It also tests for Simplex mode and enables
457 normal dual channel support.
459 If you say Y here, you also need to say Y to "Use DMA by default

467 depends on BLK_DEV_ALI15X3
469 This allows for UltraDMA support for WDC drives that ignore CRC
470 checking. You are a fool for enabling this option, but there have
471 been requests. DO NOT COMPLAIN IF YOUR DRIVE HAS FS CORRUPTION, IF
472 YOU ENABLE THIS! No one will listen, just laugh for ignoring this

637 interrupt. This add-on card is a bootable PCI UDMA controller. Since
638 multiple cards can be installed and there are BIOS ROM problems that
639 happen if the BIOS revisions of all installed cards (three-max) do
640 not match, the driver attempts to do dynamic tuning of the chipset
641 at boot-time for max-speed. Ultra33 BIOS 1.25 or newer is required
642 for more than one card. This card may require that you say Y to
643 "Special UDMA Feature".

653 config PDC202XX_BURST
654 bool "Special UDMA Feature"
655 depends on BLK_DEV_PDC202XX_OLD
657 This option causes the pdc202xx driver to enable UDMA modes on the
658 PDC202xx even when the PDC202xx BIOS has not done so.
660 It was originally designed for the PDC20246/Ultra33, whose BIOS will
661 only setup UDMA on the first two PDC20246 cards. It has also been
662 used successfully on a PDC20265/Ultra100, allowing use of UDMA modes
663 when the PDC20265 BIOS has been disabled (for faster boot up).

724 This driver ensures (U)DMA support for Victory66 SouthBridges for
725 SMsC with Intel NorthBridges. This is an Ultra66 based chipset.
726 The nice thing about it is that you can mix Ultra/DMA/PIO devices
727 and it will handle timing cycles. Since this is an improved
728 look-a-like to the PIIX4 it should be a nice addition.

871 This driver provides support for the so-called `IDE doublers' (made
872 by various manufacturers, e.g. Eyetech) that can be connected to the
873 builtin IDE interface of some Amiga models. Using such an IDE
874 doubler, you can connect up to four instead of two IDE devices on
875 the Amiga's builtin IDE interface.
877 Note that the normal Amiga Gayle IDE driver may not work correctly
878 if you have an IDE doubler and don't enable this driver!

971 then pick your particular IDE chip from among the following options.
972 This enhanced support may be necessary for Linux to be able to
973 access the 3rd/4th drives in some systems. It may also enable
974 setting of higher speed I/O rates to improve system performance with
975 these chipsets. Most of these also require special kernel boot
976 parameters to actually turn on the support at runtime; you can find
977 a list of these in the file <file:Documentation/ide.txt>.

1048 There are unclear terms in ATA-4 and ATA-5 standards how certain
1049 hardware (an 80c ribbon) should be detected. Different interpretations
1050 of the standards have been released in hardware. This causes problems:
1051 for example, a host with Ultra Mode 4 (or higher) will not run
1052 in that mode with an 80c ribbon.
1054 If you are experiencing compatibility or performance problems, you
1055 MAY try to answer Y here. However, it does not necessarily solve
1056 any of your problems, it could even cause more of them.

1062 config BLK_DEV_HD_ONLY
1063 bool "Old hard disk (MFM/RLL/IDE) driver"
1064 depends on BLK_DEV_IDE=n
1066 There are two drivers for MFM/RLL/IDE hard disks. Most people use
1067 the newer enhanced driver, but this old one is still around for two
1068 reasons. Some older systems have strange timing problems and seem to
1069 work only with the old driver (which itself does not work with some
1070 newer systems). The other reason is that the old driver is smaller,
1071 since it lacks the enhanced functionality of the new one. This makes
1072 it a good choice for systems with very tight memory restrictions, or
1073 for systems with only older MFM/RLL/ESDI drives. Choosing the old
1074 driver can save 13 KB or so of kernel memory.
1076 If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1077 instead of this one. For more detailed information, read the
