8 tristate "ATA/ATAPI/MFM/RLL support"
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 || IA64 || EMBEDDED
61 This is the maximum number of IDE hardware interfaces that will
62 be supported by the driver. Make sure it is at least as high as
63 the number of IDE interfaces in your system.
66 tristate "Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support"
68 If you say Y here, you will use the full-featured IDE driver to
69 control up to ten ATA/IDE interfaces, each being able to serve a
70 "master" and a "slave" device, for a total of up to twenty ATA/IDE
71 disk/cdrom/tape/floppy drives.
73 Useful information about large (>540 MB) IDE disks, multiple
74 interfaces, what to do if ATA/IDE devices are not automatically
75 detected, sound card ATA/IDE ports, module support, and other
76 topics, is contained in <file:Documentation/ide.txt>. For detailed
77 information about hard drives, consult the Disk-HOWTO and the
78 Multi-Disk-HOWTO, available from
79 <http://www.tldp.org/docs.html#howto>.
81 To fine-tune ATA/IDE drive/interface parameters for improved
82 performance, look for the hdparm package at
83 <ftp://ibiblio.org/pub/Linux/system/hardware/>.
85 To compile this driver as a module, choose M here and read
86 <file:Documentation/ide.txt>. The module will be called ide-mod.
87 Do not compile this driver as a module if your root file system (the
88 one containing the directory /) is located on an IDE device.
90 If you have one or more IDE drives, say Y or M here. If your system
91 has no IDE drives, or if memory requirements are really tight, you
92 could say N here, and select the "Old hard disk driver" below
93 instead to save about 13 KB of memory in the kernel.

99 config BLK_DEV_IDE_SATA
100 bool "Support for SATA (deprecated; conflicts with libata SATA driver)"
103 There are two drivers for Serial ATA controllers.
105 The main driver, "libata", uses the SCSI subsystem
106 and supports most modern SATA controllers. In order to use it
107 you may take a look at "Serial ATA (prod) and Parallel ATA
108 (experimental) drivers".
110 The IDE driver (which you are currently configuring) supports
111 a few first-generation SATA controllers.
113 In order to eliminate conflicts between the two subsystems,
114 this config option enables the IDE driver's SATA support.
115 Normally this is disabled, as it is preferred that libata
116 supports SATA controllers, and this (IDE) driver supports
121 config BLK_DEV_HD_IDE
122 bool "Use old disk-only driver on primary interface"
123 depends on (X86 || SH_MPC1211)
125 There are two drivers for MFM/RLL/IDE disks. Most people use just
126 the new enhanced driver by itself. This option however installs the
127 old hard disk driver to control the primary IDE/disk interface in
128 the system, leaving the new enhanced IDE driver to take care of only
129 the 2nd/3rd/4th IDE interfaces. Doing this will prevent you from
130 having an IDE/ATAPI CD-ROM or tape drive connected to the primary
131 IDE interface. Choosing this option may be useful for older systems
132 which have MFM/RLL/ESDI controller+drives at the primary port
133 address (0x1f0), along with IDE drives at the secondary/3rd/4th port
136 Normally, just say N here; you will then use the new driver for all
139 config BLK_DEV_IDEDISK
140 tristate "Include IDE/ATA-2 DISK support"
142 This will include enhanced support for MFM/RLL/IDE hard disks. If
143 you have a MFM/RLL/IDE disk, and there is no special reason to use
144 the old hard disk driver instead, say Y. If you have an SCSI-only
145 system, you can say N here.
147 To compile this driver as a module, choose M here: the
148 module will be called ide-disk.
149 Do not compile this driver as a module if your root file system
150 (the one containing the directory /) is located on the IDE disk.
154 config IDEDISK_MULTI_MODE
155 bool "Use multi-mode by default"
157 If you get this error, try to say Y here:
159 hda: set_multmode: status=0x51 { DriveReady SeekComplete Error }
160 hda: set_multmode: error=0x04 { DriveStatusError }
165 tristate "PCMCIA IDE support"
168 Support for Compact Flash cards, outboard IDE disks, tape drives,
169 and CD-ROM drives connected through a PCMCIA card.
171 config BLK_DEV_DELKIN
172 tristate "Cardbus IDE support (Delkin/ASKA/Workbit)"
173 depends on CARDBUS && PCI
175 Support for Delkin, ASKA, and Workbit Cardbus CompactFlash
176 Adapters. This may also work for similar SD and XD adapters.
179 tristate "Include IDE/ATAPI CDROM support"
181 If you have a CD-ROM drive using the ATAPI protocol, say Y. ATAPI is
182 a newer protocol used by IDE CD-ROM and TAPE drives, similar to the
183 SCSI protocol. Most new CD-ROM drives use ATAPI, including the
184 NEC-260, Mitsumi FX400, Sony 55E, and just about all non-SCSI
185 double(2X) or better speed drives.
187 If you say Y here, the CD-ROM drive will be identified at boot time
188 along with other IDE devices, as "hdb" or "hdc", or something
189 similar (check the boot messages with dmesg). If this is your only
190 CD-ROM drive, you can say N to all other CD-ROM options, but be sure
191 to say Y or M to "ISO 9660 CD-ROM file system support".
193 Note that older versions of LILO (LInux LOader) cannot properly deal
194 with IDE/ATAPI CD-ROMs, so install LILO 16 or higher, available from
195 <http://lilo.go.dyndns.org/>.
197 To compile this driver as a module, choose M here: the
198 module will be called ide-cd.
200 config BLK_DEV_IDETAPE
201 tristate "Include IDE/ATAPI TAPE support (EXPERIMENTAL)"
202 depends on EXPERIMENTAL
204 If you have an IDE tape drive using the ATAPI protocol, say Y.
205 ATAPI is a newer protocol used by IDE tape and CD-ROM drives,
206 similar to the SCSI protocol. If you have an SCSI tape drive
207 however, you can say N here.
209 You should also say Y if you have an OnStream DI-30 tape drive; this
210 will not work with the SCSI protocol, until there is support for the
211 SC-30 and SC-50 versions.
213 If you say Y here, the tape drive will be identified at boot time
214 along with other IDE devices, as "hdb" or "hdc", or something
215 similar, and will be mapped to a character device such as "ht0"
216 (check the boot messages with dmesg). Be sure to consult the
217 <file:drivers/ide/ide-tape.c> and <file:Documentation/ide.txt> files
218 for usage information.
220 To compile this driver as a module, choose M here: the
221 module will be called ide-tape.
223 config BLK_DEV_IDEFLOPPY
224 tristate "Include IDE/ATAPI FLOPPY support"
226 If you have an IDE floppy drive which uses the ATAPI protocol,
227 answer Y. ATAPI is a newer protocol used by IDE CD-ROM/tape/floppy
228 drives, similar to the SCSI protocol.
230 The LS-120 and the IDE/ATAPI Iomega ZIP drive are also supported by
231 this driver. For information about jumper settings and the question
232 of when a ZIP drive uses a partition table, see
233 <http://www.win.tue.nl/~aeb/linux/zip/zip-1.html>.
234 (ATAPI PD-CD/CDR drives are not supported by this driver; support
235 for PD-CD/CDR drives is available if you answer Y to
236 "SCSI emulation support", below).
238 If you say Y here, the FLOPPY drive will be identified along with
239 other IDE devices, as "hdb" or "hdc", or something similar (check
240 the boot messages with dmesg).
242 To compile this driver as a module, choose M here: the
243 module will be called ide-floppy.
245 config BLK_DEV_IDESCSI
246 tristate "SCSI emulation support"
249 WARNING: ide-scsi is no longer needed for cd writing applications!
250 The 2.6 kernel supports direct writing to ide-cd, which eliminates
251 the need for ide-scsi + the entire scsi stack just for writing a
252 cd. The new method is more efficient in every way.
254 This will provide SCSI host adapter emulation for IDE ATAPI devices,
255 and will allow you to use a SCSI device driver instead of a native
258 This is useful if you have an ATAPI device for which no native
259 driver has been written (for example, an ATAPI PD-CD drive);
260 you can then use this emulation together with an appropriate SCSI
261 device driver. In order to do this, say Y here and to "SCSI support"
262 and "SCSI generic support", below. You must then provide the kernel
263 command line "hdx=ide-scsi" (try "man bootparam" or see the
264 documentation of your boot loader (lilo or loadlin) about how to
265 pass options to the kernel at boot time) for devices if you want the
266 native EIDE sub-drivers to skip over the native support, so that
267 this SCSI emulation can be used instead.
269 Note that this option does NOT allow you to attach SCSI devices to a
270 box that doesn't have a SCSI host adapter installed.
272 If both this SCSI emulation and native ATAPI support are compiled
273 into the kernel, the native support will be used.
275 config BLK_DEV_IDEACPI
276 bool "IDE ACPI support"
279 Implement ACPI support for generic IDE devices. On modern
280 machines ACPI support is required to properly handle ACPI S3 states.
282 config IDE_TASK_IOCTL
283 bool "IDE Taskfile Access"
285 This is a direct raw access to the media. It is a complex but
286 elegant solution to test and validate the domain of the hardware and
287 perform below the driver data recovery if needed. This is the most
288 basic form of media-forensics.
290 If you are unsure, say N here.
293 bool "legacy /proc/ide/ support"
294 depends on IDE && PROC_FS
297 This option enables support for the various files in
298 /proc/ide. In Linux 2.6 this has been superseded by
299 files in sysfs but many legacy applications rely on this.
303 comment "IDE chipset support/bugfixes"
306 tristate "generic/default IDE chipset support"
311 config BLK_DEV_PLATFORM
312 tristate "Platform driver for IDE interfaces"
314 This is the platform IDE driver, used mostly for Memory Mapped
315 IDE devices, like Compact Flashes running in True IDE mode.
319 config BLK_DEV_CMD640
320 bool "CMD640 chipset bugfix/support"
323 The CMD-Technologies CMD640 IDE chip is used on many common 486 and
324 Pentium motherboards, usually in combination with a "Neptune" or
325 "SiS" chipset. Unfortunately, it has a number of rather nasty
326 design flaws that can cause severe data corruption under many common
327 conditions. Say Y here to include code which tries to automatically
328 detect and correct the problems under Linux. This option also
329 enables access to the secondary IDE ports in some CMD640 based
332 This driver will work automatically in PCI based systems (most new
333 systems have PCI slots). But if your system uses VESA local bus
334 (VLB) instead of PCI, you must also supply a kernel boot parameter
335 to enable the CMD640 bugfix/support: "ide0=cmd640_vlb". (Try "man
336 bootparam" or see the documentation of your boot loader about how to
337 pass options to the kernel.)
339 The CMD640 chip is also used on add-in cards by Acculogic, and on
340 the "CSA-6400E PCI to IDE controller" that some people have. For
341 details, read <file:Documentation/ide.txt>.
343 config BLK_DEV_CMD640_ENHANCED
344 bool "CMD640 enhanced support"
345 depends on BLK_DEV_CMD640
347 This option includes support for setting/autotuning PIO modes and
348 prefetch on CMD640 IDE interfaces. For details, read
349 <file:Documentation/ide.txt>. If you have a CMD640 IDE interface
350 and your BIOS does not already do this for you, then say Y here.
353 config BLK_DEV_IDEPNP
354 bool "PNP EIDE support"
358 If you have a PnP (Plug and Play) compatible EIDE card and
359 would like the kernel to automatically detect and activate
362 config BLK_DEV_IDEPCI
363 bool "PCI IDE chipset support" if PCI
364 default BLK_DEV_IDEDMA_PMAC if PPC_PMAC && BLK_DEV_IDEDMA_PMAC
366 Say Y here for PCI systems which use IDE drive(s).
367 This option helps the IDE driver to automatically detect and
368 configure all PCI-based IDE interfaces in your system.
370 config IDEPCI_SHARE_IRQ
371 bool "Sharing PCI IDE interrupts support"
372 depends on PCI && BLK_DEV_IDEPCI
374 Some ATA/IDE chipsets have hardware support which allows for
375 sharing a single IRQ with other cards. To enable support for
376 this in the ATA/IDE driver, say Y here.
378 It is safe to say Y to this question, in most cases.
381 config IDEPCI_PCIBUS_ORDER
382 def_bool PCI && BLK_DEV_IDE=y && BLK_DEV_IDEPCI
384 config BLK_DEV_OFFBOARD
385 bool "Boot off-board chipsets first support"
386 depends on PCI && BLK_DEV_IDEPCI
388 Normally, IDE controllers built into the motherboard (on-board
389 controllers) are assigned to ide0 and ide1 while those on add-in PCI
390 cards (off-board controllers) are relegated to ide2 and ide3.
391 Answering Y here will allow you to reverse the situation, with
392 off-board controllers on ide0/1 and on-board controllers on ide2/3.
393 This can improve the usability of some boot managers such as lilo
394 when booting from a drive on an off-board controller.
396 If you say Y here, and you actually want to reverse the device scan
397 order as explained above, you also need to issue the kernel command
398 line option "ide=reverse". (Try "man bootparam" or see the
399 documentation of your boot loader (lilo or loadlin) about how to
400 pass options to the kernel at boot time.)
402 Note that, if you do this, the order of the hd* devices will be
403 rearranged which may require modification of fstab and other files.
407 config BLK_DEV_GENERIC
408 tristate "Generic PCI IDE Chipset Support"
409 depends on BLK_DEV_IDEPCI
411 This option provides generic support for various PCI IDE Chipsets
412 which otherwise might not be supported.
414 config BLK_DEV_OPTI621
415 tristate "OPTi 82C621 chipset enhanced support (EXPERIMENTAL)"
416 depends on PCI && BLK_DEV_IDEPCI && EXPERIMENTAL
418 This is a driver for the OPTi 82C621 EIDE controller.

422 tristate "RZ1000 chipset bugfix/support"
423 depends on PCI && BLK_DEV_IDEPCI && X86
425 The PC-Technologies RZ1000 IDE chip is used on many common 486 and
426 Pentium motherboards, usually along with the "Neptune" chipset.
427 Unfortunately, it has a rather nasty design flaw that can cause
428 severe data corruption under many conditions. Say Y here to include
429 code which automatically detects and corrects the problem under
430 Linux. This may slow disk throughput by a few percent, but at least
431 things will operate 100% reliably.
433 config BLK_DEV_IDEDMA_PCI
434 bool "Generic PCI bus-master DMA support"
435 depends on PCI && BLK_DEV_IDEPCI
437 If your PCI system uses IDE drive(s) (as opposed to SCSI, say) and
438 is capable of bus-master DMA operation (most Pentium PCI systems),
439 you will want to say Y here to reduce CPU overhead. You can then use
440 the "hdparm" utility to enable DMA for drives for which it was not
441 enabled automatically. By default, DMA is not enabled automatically
442 for these drives, but you can change that by saying Y to the
443 following question "Use DMA by default when available". You can get
444 the latest version of the hdparm utility from
445 <ftp://ibiblio.org/pub/Linux/system/hardware/>.
447 Read the comments at the beginning of <file:drivers/ide/ide-dma.c>

464 This is used if you know your ATAPI Devices are going to fail DMA
467 Generally say N here.
469 config BLK_DEV_AEC62XX
470 tristate "AEC62XX chipset support"
472 This driver adds explicit support for Acard AEC62xx (Artop ATP8xx)
473 IDE controllers. This allows the kernel to change PIO, DMA and UDMA
474 speeds and to configure the chip to optimum performance.
476 config BLK_DEV_ALI15X3
477 tristate "ALI M15x3 chipset support"
479 This driver ensures (U)DMA support for ALI 1533, 1543 and 1543C
480 onboard chipsets. It also tests for Simplex mode and enables
481 normal dual channel support.
483 If you say Y here, you also need to say Y to "Use DMA by default
484 when available", above. Please read the comments at the top of
485 <file:drivers/ide/pci/alim15x3.c>.
490 bool "ALI M15x3 WDC support (DANGEROUS)"
491 depends on BLK_DEV_ALI15X3
493 This allows for UltraDMA support for WDC drives that ignore CRC
494 checking. You are a fool for enabling this option, but there have
495 been requests. DO NOT COMPLAIN IF YOUR DRIVE HAS FS CORRUPTION, IF
496 YOU ENABLE THIS! No one will listen, just laugh for ignoring this
499 Using this option can allow WDC drives to run at ATA-4/5 transfer
500 rates with only an ATA-2 support structure.

505 tristate "AMD and nVidia IDE support"
507 This driver adds explicit support for AMD-7xx and AMD-8111 chips

573 This driver adds up to 4 more EIDE devices sharing a single
574 interrupt. The HPT343 chipset in its current form is a non-bootable
575 controller; the HPT345/HPT363 chipset is a bootable (needs BIOS FIX)
576 PCI UDMA controllers. This driver requires dynamic tuning of the

603 for this problem are special LILO commands for redirecting the
604 reference to device 0x80. The other solution is to say Y to "Boot
605 off-board chipsets first support" (CONFIG_BLK_DEV_OFFBOARD) unless
606 your mother board has the chipset natively mounted. Regardless one
607 should use the fore mentioned option and call at LILO or include

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

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

1097 There are two drivers for MFM/RLL/IDE hard disks. Most people use
1098 the newer enhanced driver, but this old one is still around for two
1099 reasons. Some older systems have strange timing problems and seem to
1100 work only with the old driver (which itself does not work with some
1101 newer systems). The other reason is that the old driver is smaller,
1102 since it lacks the enhanced functionality of the new one. This makes
1103 it a good choice for systems with very tight memory restrictions, or
1104 for systems with only older MFM/RLL/ESDI drives. Choosing the old
1105 driver can save 13 KB or so of kernel memory.
1107 If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
