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

103 config BLK_DEV_IDE_SATA
104 bool "Support for SATA (deprecated; conflicts with libata SATA driver)"
107 There are two drivers for Serial ATA controllers.
109 The main driver, "libata", uses the SCSI subsystem
110 and supports most modern SATA controllers. In order to use it
111 you may take a look at "Serial ATA (prod) and Parallel ATA
112 (experimental) drivers".
114 The IDE driver (which you are currently configuring) supports
115 a few first-generation SATA controllers.
117 In order to eliminate conflicts between the two subsystems,
118 this config option enables the IDE driver's SATA support.
119 Normally this is disabled, as it is preferred that libata
120 supports SATA controllers, and this (IDE) driver supports
125 config BLK_DEV_HD_IDE
126 bool "Use old disk-only driver on primary interface"
127 depends on (X86 || SH_MPC1211)
129 There are two drivers for MFM/RLL/IDE disks. Most people use just
130 the new enhanced driver by itself. This option however installs the
131 old hard disk driver to control the primary IDE/disk interface in
132 the system, leaving the new enhanced IDE driver to take care of only
133 the 2nd/3rd/4th IDE interfaces. Doing this will prevent you from
134 having an IDE/ATAPI CD-ROM or tape drive connected to the primary
135 IDE interface. Choosing this option may be useful for older systems
136 which have MFM/RLL/ESDI controller+drives at the primary port
137 address (0x1f0), along with IDE drives at the secondary/3rd/4th port
140 Normally, just say N here; you will then use the new driver for all
143 config BLK_DEV_IDEDISK
144 tristate "Include IDE/ATA-2 DISK support"
146 This will include enhanced support for MFM/RLL/IDE hard disks. If
147 you have a MFM/RLL/IDE disk, and there is no special reason to use
148 the old hard disk driver instead, say Y. If you have an SCSI-only
149 system, you can say N here.
151 To compile this driver as a module, choose M here: the
152 module will be called ide-disk.
153 Do not compile this driver as a module if your root file system
154 (the one containing the directory /) is located on the IDE disk.
158 config IDEDISK_MULTI_MODE
159 bool "Use multiple sector mode for Programmed Input/Output by default"
161 This setting is irrelevant for most IDE disks, with direct memory
162 access, to which multiple sector mode does not apply. Multiple sector
163 mode is a feature of most modern IDE hard drives, permitting the
164 transfer of multiple sectors per Programmed Input/Output interrupt,
165 rather than the usual one sector per interrupt. When this feature is
166 enabled, it can reduce operating system overhead for disk Programmed
167 Input/Output. On some systems, it also can increase the data
168 throughput of Programmed Input/Output. Some drives, however, seemed
169 to run slower with multiple sector mode enabled. Some drives claimed
170 to support multiple sector mode, but lost data at some settings.
171 Under rare circumstances, such failures could result in massive
172 filesystem corruption.
174 If you get the following error, try to say Y here:
176 hda: set_multmode: status=0x51 { DriveReady SeekComplete Error }
177 hda: set_multmode: error=0x04 { DriveStatusError }
182 tristate "PCMCIA IDE support"
185 Support for Compact Flash cards, outboard IDE disks, tape drives,
186 and CD-ROM drives connected through a PCMCIA card.

189 tristate "Cardbus IDE support (Delkin/ASKA/Workbit)"
190 depends on CARDBUS && PCI
192 Support for Delkin, ASKA, and Workbit Cardbus CompactFlash
193 Adapters. This may also work for similar SD and XD adapters.
196 tristate "Include IDE/ATAPI CDROM support"
198 If you have a CD-ROM drive using the ATAPI protocol, say Y. ATAPI is
199 a newer protocol used by IDE CD-ROM and TAPE drives, similar to the
200 SCSI protocol. Most new CD-ROM drives use ATAPI, including the
201 NEC-260, Mitsumi FX400, Sony 55E, and just about all non-SCSI
202 double(2X) or better speed drives.
204 If you say Y here, the CD-ROM drive will be identified at boot time
205 along with other IDE devices, as "hdb" or "hdc", or something
206 similar (check the boot messages with dmesg). If this is your only
207 CD-ROM drive, you can say N to all other CD-ROM options, but be sure
208 to say Y or M to "ISO 9660 CD-ROM file system support".
210 To compile this driver as a module, choose M here: the
211 module will be called ide-cd.
213 config BLK_DEV_IDECD_VERBOSE_ERRORS
214 bool "Verbose error logging for IDE/ATAPI CDROM driver" if EMBEDDED
215 depends on BLK_DEV_IDECD
218 Turn this on to have the driver print out the meanings of the
219 ATAPI error codes. This will use up additional 8kB of kernel-space
222 config BLK_DEV_IDETAPE
223 tristate "Include IDE/ATAPI TAPE support"
225 If you have an IDE tape drive using the ATAPI protocol, say Y.
226 ATAPI is a newer protocol used by IDE tape and CD-ROM drives,
227 similar to the SCSI protocol. If you have an SCSI tape drive
228 however, you can say N here.
230 You should also say Y if you have an OnStream DI-30 tape drive; this
231 will not work with the SCSI protocol, until there is support for the
232 SC-30 and SC-50 versions.
234 If you say Y here, the tape drive will be identified at boot time
235 along with other IDE devices, as "hdb" or "hdc", or something
236 similar, and will be mapped to a character device such as "ht0"
237 (check the boot messages with dmesg). Be sure to consult the
238 <file:drivers/ide/ide-tape.c> and <file:Documentation/ide/ide.txt>
239 files for usage information.
241 To compile this driver as a module, choose M here: the
242 module will be called ide-tape.
244 config BLK_DEV_IDEFLOPPY
245 tristate "Include IDE/ATAPI FLOPPY support"
247 If you have an IDE floppy drive which uses the ATAPI protocol,
248 answer Y. ATAPI is a newer protocol used by IDE CD-ROM/tape/floppy
249 drives, similar to the SCSI protocol.
251 The LS-120 and the IDE/ATAPI Iomega ZIP drive are also supported by
252 this driver. For information about jumper settings and the question
253 of when a ZIP drive uses a partition table, see
254 <http://www.win.tue.nl/~aeb/linux/zip/zip-1.html>.
255 (ATAPI PD-CD/CDR drives are not supported by this driver; support
256 for PD-CD/CDR drives is available if you answer Y to
257 "SCSI emulation support", below).
259 If you say Y here, the FLOPPY drive will be identified along with
260 other IDE devices, as "hdb" or "hdc", or something similar (check
261 the boot messages with dmesg).
263 To compile this driver as a module, choose M here: the
264 module will be called ide-floppy.
266 config BLK_DEV_IDESCSI
267 tristate "SCSI emulation support"
270 WARNING: ide-scsi is no longer needed for cd writing applications!
271 The 2.6 kernel supports direct writing to ide-cd, which eliminates
272 the need for ide-scsi + the entire scsi stack just for writing a
273 cd. The new method is more efficient in every way.
275 This will provide SCSI host adapter emulation for IDE ATAPI devices,
276 and will allow you to use a SCSI device driver instead of a native
279 This is useful if you have an ATAPI device for which no native
280 driver has been written (for example, an ATAPI PD-CD drive);
281 you can then use this emulation together with an appropriate SCSI
282 device driver. In order to do this, say Y here and to "SCSI support"
283 and "SCSI generic support", below. You must then provide the kernel
284 command line "hdx=ide-scsi" (try "man bootparam" or see the
285 documentation of your boot loader (lilo or loadlin) about how to
286 pass options to the kernel at boot time) for devices if you want the
287 native EIDE sub-drivers to skip over the native support, so that
288 this SCSI emulation can be used instead.
290 Note that this option does NOT allow you to attach SCSI devices to a
291 box that doesn't have a SCSI host adapter installed.
293 If both this SCSI emulation and native ATAPI support are compiled
294 into the kernel, the native support will be used.
296 config BLK_DEV_IDEACPI
297 bool "IDE ACPI support"
300 Implement ACPI support for generic IDE devices. On modern
301 machines ACPI support is required to properly handle ACPI S3 states.
303 config IDE_TASK_IOCTL
304 bool "IDE Taskfile Access"
306 This is a direct raw access to the media. It is a complex but
307 elegant solution to test and validate the domain of the hardware and
308 perform below the driver data recovery if needed. This is the most
309 basic form of media-forensics.
311 If you are unsure, say N here.
314 bool "legacy /proc/ide/ support"
315 depends on IDE && PROC_FS
318 This option enables support for the various files in
319 /proc/ide. In Linux 2.6 this has been superseded by
320 files in sysfs but many legacy applications rely on this.

343 The CMD-Technologies CMD640 IDE chip is used on many common 486 and
344 Pentium motherboards, usually in combination with a "Neptune" or
345 "SiS" chipset. Unfortunately, it has a number of rather nasty
346 design flaws that can cause severe data corruption under many common
347 conditions. Say Y here to include code which tries to automatically
348 detect and correct the problems under Linux. This option also
349 enables access to the secondary IDE ports in some CMD640 based
352 This driver will work automatically in PCI based systems (most new
353 systems have PCI slots). But if your system uses VESA local bus
354 (VLB) instead of PCI, you must also supply a kernel boot parameter
355 to enable the CMD640 bugfix/support: "ide0=cmd640_vlb". (Try "man
356 bootparam" or see the documentation of your boot loader about how to
357 pass options to the kernel.)
359 The CMD640 chip is also used on add-in cards by Acculogic, and on

411 Normally, IDE controllers built into the motherboard (on-board
412 controllers) are assigned to ide0 and ide1 while those on add-in PCI
413 cards (off-board controllers) are relegated to ide2 and ide3.
414 Answering Y here will allow you to reverse the situation, with

672 interrupt. This add-on card is a bootable PCI UDMA controller. Since
673 multiple cards can be installed and there are BIOS ROM problems that
674 happen if the BIOS revisions of all installed cards (three-max) do
675 not match, the driver attempts to do dynamic tuning of the chipset
676 at boot-time for max-speed. Ultra33 BIOS 1.25 or newer is required

1119 There are two drivers for MFM/RLL/IDE hard disks. Most people use
1120 the newer enhanced driver, but this old one is still around for two
1121 reasons. Some older systems have strange timing problems and seem to
1122 work only with the old driver (which itself does not work with some
1123 newer systems). The other reason is that the old driver is smaller,
1124 since it lacks the enhanced functionality of the new one. This makes
1125 it a good choice for systems with very tight memory restrictions, or
1126 for systems with only older MFM/RLL/ESDI drives. Choosing the old
1127 driver can save 13 KB or so of kernel memory.
1129 If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
