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
63 This is the maximum number of IDE hardware interfaces that will
64 be supported by the driver. Make sure it is at least as high as
65 the number of IDE interfaces in your system.
68 tristate "Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support"
70 If you say Y here, you will use the full-featured IDE driver to
71 control up to ten ATA/IDE interfaces, each being able to serve a
72 "master" and a "slave" device, for a total of up to twenty ATA/IDE
73 disk/cdrom/tape/floppy drives.
75 Useful information about large (>540 MB) IDE disks, multiple
76 interfaces, what to do if ATA/IDE devices are not automatically
77 detected, sound card ATA/IDE ports, module support, and other
78 topics, is contained in <file:Documentation/ide.txt>. For detailed
79 information about hard drives, consult the Disk-HOWTO and the
80 Multi-Disk-HOWTO, available from
81 <http://www.tldp.org/docs.html#howto>.
83 To fine-tune ATA/IDE drive/interface parameters for improved
84 performance, look for the hdparm package at
85 <ftp://ibiblio.org/pub/Linux/system/hardware/>.
87 To compile this driver as a module, choose M here and read
88 <file:Documentation/ide.txt>. The module will be called ide-mod.
89 Do not compile this driver as a module if your root file system (the
90 one containing the directory /) is located on an IDE device.
92 If you have one or more IDE drives, say Y or M here. If your system
93 has no IDE drives, or if memory requirements are really tight, you
94 could say N here, and select the "Old hard disk driver" below
95 instead to save about 13 KB of memory in the kernel.

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

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

402 depends on PCI && BLK_DEV_IDEPCI && X86
404 The PC-Technologies RZ1000 IDE chip is used on many common 486 and
405 Pentium motherboards, usually along with the "Neptune" chipset.
406 Unfortunately, it has a rather nasty design flaw that can cause
407 severe data corruption under many conditions. Say Y here to include
408 code which automatically detects and corrects the problem under
409 Linux. This may slow disk throughput by a few percent, but at least
410 things will operate 100% reliably.
412 config BLK_DEV_IDEDMA_PCI
413 bool "Generic PCI bus-master DMA support"
414 depends on PCI && BLK_DEV_IDEPCI
416 If your PCI system uses IDE drive(s) (as opposed to SCSI, say) and
417 is capable of bus-master DMA operation (most Pentium PCI systems),
418 you will want to say Y here to reduce CPU overhead. You can then use
419 the "hdparm" utility to enable DMA for drives for which it was not
420 enabled automatically. By default, DMA is not enabled automatically
421 for these drives, but you can change that by saying Y to the
422 following question "Use DMA by default when available". You can get
423 the latest version of the hdparm utility from
424 <ftp://ibiblio.org/pub/Linux/system/hardware/>.
426 Read the comments at the beginning of <file:drivers/ide/ide-dma.c>

456 tristate "ALI M15x3 chipset support"
458 This driver ensures (U)DMA support for ALI 1533, 1543 and 1543C
459 onboard chipsets. It also tests for Simplex mode and enables
460 normal dual channel support.
462 If you say Y here, you also need to say Y to "Use DMA by default
463 when available", above. Please read the comments at the top of
464 <file:drivers/ide/pci/alim15x3.c>.
469 bool "ALI M15x3 WDC support (DANGEROUS)"
470 depends on BLK_DEV_ALI15X3
472 This allows for UltraDMA support for WDC drives that ignore CRC
473 checking. You are a fool for enabling this option, but there have
474 been requests. DO NOT COMPLAIN IF YOUR DRIVE HAS FS CORRUPTION, IF
475 YOU ENABLE THIS! No one will listen, just laugh for ignoring this

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

660 This option causes the pdc202xx driver to enable UDMA modes on the
661 PDC202xx even when the PDC202xx BIOS has not done so.
663 It was originally designed for the PDC20246/Ultra33, whose BIOS will
664 only setup UDMA on the first two PDC20246 cards. It has also been
665 used successfully on a PDC20265/Ultra100, allowing use of UDMA modes
666 when the PDC20265 BIOS has been disabled (for faster boot up).

1069 There are two drivers for MFM/RLL/IDE hard disks. Most people use
1070 the newer enhanced driver, but this old one is still around for two
1071 reasons. Some older systems have strange timing problems and seem to
1072 work only with the old driver (which itself does not work with some
1073 newer systems). The other reason is that the old driver is smaller,
1074 since it lacks the enhanced functionality of the new one. This makes
1075 it a good choice for systems with very tight memory restrictions, or
1076 for systems with only older MFM/RLL/ESDI drives. Choosing the old
1077 driver can save 13 KB or so of kernel memory.
1079 If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1080 instead of this one. For more detailed information, read the
