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

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

399 The PC-Technologies RZ1000 IDE chip is used on many common 486 and
400 Pentium motherboards, usually along with the "Neptune" chipset.
401 Unfortunately, it has a rather nasty design flaw that can cause
402 severe data corruption under many conditions. Say Y here to include
403 code which automatically detects and corrects the problem under
404 Linux. This may slow disk throughput by a few percent, but at least
405 things will operate 100% reliably.
407 config BLK_DEV_SL82C105
408 tristate "Winbond SL82c105 support"
409 depends on PCI && (PPC || ARM) && BLK_DEV_IDEPCI
411 If you have a Winbond SL82c105 IDE controller, say Y here to enable
412 special configuration for this chip. This is common on various CHRP
413 motherboards, but could be used elsewhere. If in doubt, say Y.
415 config BLK_DEV_IDEDMA_PCI
416 bool "Generic PCI bus-master DMA support"
417 depends on PCI && BLK_DEV_IDEPCI
419 If your PCI system uses IDE drive(s) (as opposed to SCSI, say) and
420 is capable of bus-master DMA operation (most Pentium PCI systems),
421 you will want to say Y here to reduce CPU overhead. You can then use
422 the "hdparm" utility to enable DMA for drives for which it was not
423 enabled automatically. By default, DMA is not enabled automatically
424 for these drives, but you can change that by saying Y to the
425 following question "Use DMA by default when available". You can get
426 the latest version of the hdparm utility from
427 <ftp://ibiblio.org/pub/Linux/system/hardware/>.

444 bool "Use PCI DMA by default when available"
446 Prior to kernel version 2.1.112, Linux used to automatically use
447 DMA for IDE drives and chipsets which support it. Due to concerns
448 about a couple of cases where buggy hardware may have caused damage,
449 the default is now to NOT use DMA automatically. To revert to the
450 previous behaviour, say Y to this question.
452 If you suspect your hardware is at all flakey, say N here.
453 Do NOT email the IDE kernel people regarding this issue!
455 It is normally safe to answer Y to this question unless your
456 motherboard uses a VIA VP2 chipset, in which case you should say N.

459 bool "Enable DMA only for disks "
460 depends on IDEDMA_PCI_AUTO
462 This is used if you know your ATAPI Devices are going to fail DMA
465 Generally say N here.

468 tristate "AEC62XX chipset support"
470 This driver adds explicit support for Acard AEC62xx (Artop ATP8xx)
471 IDE controllers. This allows the kernel to change PIO, DMA and UDMA
472 speeds and to configure the chip to optimum performance.

475 tristate "ALI M15x3 chipset support"
477 This driver ensures (U)DMA support for ALI 1533, 1543 and 1543C
478 onboard chipsets. It also tests for Simplex mode and enables
479 normal dual channel support.

493 been requests. DO NOT COMPLAIN IF YOUR DRIVE HAS FS CORRUPTION, IF
494 YOU ENABLE THIS! No one will listen, just laugh for ignoring this

498 rates with only an ATA-2 support structure.

647 This driver adds up to 4 more EIDE devices sharing a single
648 interrupt. This add-on card is a bootable PCI UDMA controller. Since
649 multiple cards can be installed and there are BIOS ROM problems that
650 happen if the BIOS revisions of all installed cards (three-max) do
651 not match, the driver attempts to do dynamic tuning of the chipset
652 at boot-time for max-speed. Ultra33 BIOS 1.25 or newer is required
653 for more than one card. This card may require that you say Y to

671 It was originally designed for the PDC20246/Ultra33, whose BIOS will
672 only setup UDMA on the first two PDC20246 cards. It has also been
673 used succesfully on a PDC20265/Ultra100, allowing use of UDMA modes

872 This driver provides support for the so-called `IDE doublers' (made
873 by various manufacturers, e.g. Eyetech) that can be connected to the
874 builtin IDE interface of some Amiga models. Using such an IDE
875 doubler, you can connect up to four instead of two IDE devices on

1083 There are two drivers for MFM/RLL/IDE hard disks. Most people use
1084 the newer enhanced driver, but this old one is still around for two
1085 reasons. Some older systems have strange timing problems and seem to
1086 work only with the old driver (which itself does not work with some
1087 newer systems). The other reason is that the old driver is smaller,
1088 since it lacks the enhanced functionality of the new one. This makes
1089 it a good choice for systems with very tight memory restrictions, or
1090 for systems with only older MFM/RLL/ESDI drives. Choosing the old
1091 driver can save 13 KB or so of kernel memory.
1093 If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
