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 multiple sector mode for Programmed Input/Output by default"
157 This setting is irrelevant for most IDE disks, with direct memory
158 access, to which multiple sector mode does not apply. Multiple sector
159 mode is a feature of most modern IDE hard drives, permitting the
160 transfer of multiple sectors per Programmed Input/Output interrupt,
161 rather than the usual one sector per interrupt. When this feature is
162 enabled, it can reduce operating system overhead for disk Programmed
163 Input/Output. On some systems, it also can increase the data
164 throughput of Programmed Input/Output. Some drives, however, seemed
165 to run slower with multiple sector mode enabled. Some drives claimed
166 to support multiple sector mode, but lost data at some settings.
167 Under rare circumstances, such failures could result in massive
168 filesystem corruption.
170 If you get the following error, try to say Y here:
172 hda: set_multmode: status=0x51 { DriveReady SeekComplete Error }
173 hda: set_multmode: error=0x04 { DriveStatusError }
178 tristate "PCMCIA IDE support"
181 Support for Compact Flash cards, outboard IDE disks, tape drives,
182 and CD-ROM drives connected through a PCMCIA card.
184 config BLK_DEV_DELKIN
185 tristate "Cardbus IDE support (Delkin/ASKA/Workbit)"
186 depends on CARDBUS && PCI
188 Support for Delkin, ASKA, and Workbit Cardbus CompactFlash
189 Adapters. This may also work for similar SD and XD adapters.
192 tristate "Include IDE/ATAPI CDROM support"
194 If you have a CD-ROM drive using the ATAPI protocol, say Y. ATAPI is
195 a newer protocol used by IDE CD-ROM and TAPE drives, similar to the
196 SCSI protocol. Most new CD-ROM drives use ATAPI, including the
197 NEC-260, Mitsumi FX400, Sony 55E, and just about all non-SCSI
198 double(2X) or better speed drives.
200 If you say Y here, the CD-ROM drive will be identified at boot time
201 along with other IDE devices, as "hdb" or "hdc", or something
202 similar (check the boot messages with dmesg). If this is your only
203 CD-ROM drive, you can say N to all other CD-ROM options, but be sure
204 to say Y or M to "ISO 9660 CD-ROM file system support".
206 To compile this driver as a module, choose M here: the
207 module will be called ide-cd.
209 config BLK_DEV_IDETAPE
210 tristate "Include IDE/ATAPI TAPE support (EXPERIMENTAL)"
211 depends on EXPERIMENTAL
213 If you have an IDE tape drive using the ATAPI protocol, say Y.
214 ATAPI is a newer protocol used by IDE tape and CD-ROM drives,
215 similar to the SCSI protocol. If you have an SCSI tape drive
216 however, you can say N here.
218 You should also say Y if you have an OnStream DI-30 tape drive; this
219 will not work with the SCSI protocol, until there is support for the
220 SC-30 and SC-50 versions.
222 If you say Y here, the tape drive will be identified at boot time
223 along with other IDE devices, as "hdb" or "hdc", or something
224 similar, and will be mapped to a character device such as "ht0"
225 (check the boot messages with dmesg). Be sure to consult the
226 <file:drivers/ide/ide-tape.c> and <file:Documentation/ide.txt> files
227 for usage information.
229 To compile this driver as a module, choose M here: the
230 module will be called ide-tape.
232 config BLK_DEV_IDEFLOPPY
233 tristate "Include IDE/ATAPI FLOPPY support"
235 If you have an IDE floppy drive which uses the ATAPI protocol,
236 answer Y. ATAPI is a newer protocol used by IDE CD-ROM/tape/floppy
237 drives, similar to the SCSI protocol.
239 The LS-120 and the IDE/ATAPI Iomega ZIP drive are also supported by
240 this driver. For information about jumper settings and the question
241 of when a ZIP drive uses a partition table, see
242 <http://www.win.tue.nl/~aeb/linux/zip/zip-1.html>.
243 (ATAPI PD-CD/CDR drives are not supported by this driver; support
244 for PD-CD/CDR drives is available if you answer Y to
245 "SCSI emulation support", below).
247 If you say Y here, the FLOPPY drive will be identified along with
248 other IDE devices, as "hdb" or "hdc", or something similar (check
249 the boot messages with dmesg).
251 To compile this driver as a module, choose M here: the
252 module will be called ide-floppy.
254 config BLK_DEV_IDESCSI
255 tristate "SCSI emulation support"
258 WARNING: ide-scsi is no longer needed for cd writing applications!
259 The 2.6 kernel supports direct writing to ide-cd, which eliminates
260 the need for ide-scsi + the entire scsi stack just for writing a
261 cd. The new method is more efficient in every way.
263 This will provide SCSI host adapter emulation for IDE ATAPI devices,
264 and will allow you to use a SCSI device driver instead of a native
267 This is useful if you have an ATAPI device for which no native
268 driver has been written (for example, an ATAPI PD-CD drive);
269 you can then use this emulation together with an appropriate SCSI
270 device driver. In order to do this, say Y here and to "SCSI support"
271 and "SCSI generic support", below. You must then provide the kernel
272 command line "hdx=ide-scsi" (try "man bootparam" or see the
273 documentation of your boot loader (lilo or loadlin) about how to
274 pass options to the kernel at boot time) for devices if you want the
275 native EIDE sub-drivers to skip over the native support, so that
276 this SCSI emulation can be used instead.
278 Note that this option does NOT allow you to attach SCSI devices to a
279 box that doesn't have a SCSI host adapter installed.
281 If both this SCSI emulation and native ATAPI support are compiled
282 into the kernel, the native support will be used.
284 config BLK_DEV_IDEACPI
285 bool "IDE ACPI support"
288 Implement ACPI support for generic IDE devices. On modern
289 machines ACPI support is required to properly handle ACPI S3 states.
291 config IDE_TASK_IOCTL
292 bool "IDE Taskfile Access"
294 This is a direct raw access to the media. It is a complex but
295 elegant solution to test and validate the domain of the hardware and
296 perform below the driver data recovery if needed. This is the most
297 basic form of media-forensics.
299 If you are unsure, say N here.
302 bool "legacy /proc/ide/ support"
303 depends on IDE && PROC_FS
306 This option enables support for the various files in
307 /proc/ide. In Linux 2.6 this has been superseded by
308 files in sysfs but many legacy applications rely on this.

322 This is the platform IDE driver, used mostly for Memory Mapped
323 IDE devices, like Compact Flashes running in True IDE mode.
327 config BLK_DEV_CMD640
328 bool "CMD640 chipset bugfix/support"
331 The CMD-Technologies CMD640 IDE chip is used on many common 486 and
332 Pentium motherboards, usually in combination with a "Neptune" or
333 "SiS" chipset. Unfortunately, it has a number of rather nasty
334 design flaws that can cause severe data corruption under many common
335 conditions. Say Y here to include code which tries to automatically
336 detect and correct the problems under Linux. This option also
337 enables access to the secondary IDE ports in some CMD640 based
340 This driver will work automatically in PCI based systems (most new
341 systems have PCI slots). But if your system uses VESA local bus
342 (VLB) instead of PCI, you must also supply a kernel boot parameter
343 to enable the CMD640 bugfix/support: "ide0=cmd640_vlb". (Try "man
344 bootparam" or see the documentation of your boot loader about how to
345 pass options to the kernel.)
347 The CMD640 chip is also used on add-in cards by Acculogic, and on
348 the "CSA-6400E PCI to IDE controller" that some people have. For
349 details, read <file:Documentation/ide.txt>.
351 config BLK_DEV_CMD640_ENHANCED
352 bool "CMD640 enhanced support"
353 depends on BLK_DEV_CMD640
355 This option includes support for setting/autotuning PIO modes and
356 prefetch on CMD640 IDE interfaces. For details, read
357 <file:Documentation/ide.txt>. If you have a CMD640 IDE interface
358 and your BIOS does not already do this for you, then say Y here.

384 Normally, IDE controllers built into the motherboard (on-board
385 controllers) are assigned to ide0 and ide1 while those on add-in PCI
386 cards (off-board controllers) are relegated to ide2 and ide3.
387 Answering Y here will allow you to reverse the situation, with
388 off-board controllers on ide0/1 and on-board controllers on ide2/3.
389 This can improve the usability of some boot managers such as lilo
390 when booting from a drive on an off-board controller.
392 If you say Y here, and you actually want to reverse the device scan
393 order as explained above, you also need to issue the kernel command
394 line option "ide=reverse". (Try "man bootparam" or see the
395 documentation of your boot loader (lilo or loadlin) about how to
396 pass options to the kernel at boot time.)
398 Note that, if you do this, the order of the hd* devices will be
399 rearranged which may require modification of fstab and other files.

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

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

1100 bool "Old hard disk (MFM/RLL/IDE) driver"

1103 There are two drivers for MFM/RLL/IDE hard disks. Most people use
1104 the newer enhanced driver, but this old one is still around for two
1105 reasons. Some older systems have strange timing problems and seem to
1106 work only with the old driver (which itself does not work with some
1107 newer systems). The other reason is that the old driver is smaller,
1108 since it lacks the enhanced functionality of the new one. This makes
1109 it a good choice for systems with very tight memory restrictions, or
1110 for systems with only older MFM/RLL/ESDI drives. Choosing the old
1111 driver can save 13 KB or so of kernel memory.
1113 If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1114 instead of this one. For more detailed information, read the
