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_IDEDISK
126 tristate "Include IDE/ATA-2 DISK support"
128 This will include enhanced support for MFM/RLL/IDE hard disks. If
129 you have a MFM/RLL/IDE disk, and there is no special reason to use
130 the old hard disk driver instead, say Y. If you have an SCSI-only
131 system, you can say N here.
133 To compile this driver as a module, choose M here: the
134 module will be called ide-disk.
135 Do not compile this driver as a module if your root file system
136 (the one containing the directory /) is located on the IDE disk.
140 config IDEDISK_MULTI_MODE
141 bool "Use multiple sector mode for Programmed Input/Output by default"
143 This setting is irrelevant for most IDE disks, with direct memory
144 access, to which multiple sector mode does not apply. Multiple sector
145 mode is a feature of most modern IDE hard drives, permitting the
146 transfer of multiple sectors per Programmed Input/Output interrupt,
147 rather than the usual one sector per interrupt. When this feature is
148 enabled, it can reduce operating system overhead for disk Programmed
149 Input/Output. On some systems, it also can increase the data
150 throughput of Programmed Input/Output. Some drives, however, seemed
151 to run slower with multiple sector mode enabled. Some drives claimed
152 to support multiple sector mode, but lost data at some settings.
153 Under rare circumstances, such failures could result in massive
154 filesystem corruption.
156 If you get the following error, try to say Y here:
158 hda: set_multmode: status=0x51 { DriveReady SeekComplete Error }
159 hda: set_multmode: error=0x04 { DriveStatusError }

171 tristate "Cardbus IDE support (Delkin/ASKA/Workbit)"
172 depends on CARDBUS && PCI
174 Support for Delkin, ASKA, and Workbit Cardbus CompactFlash
175 Adapters. This may also work for similar SD and XD adapters.
178 tristate "Include IDE/ATAPI CDROM support"
180 If you have a CD-ROM drive using the ATAPI protocol, say Y. ATAPI is
181 a newer protocol used by IDE CD-ROM and TAPE drives, similar to the
182 SCSI protocol. Most new CD-ROM drives use ATAPI, including the
183 NEC-260, Mitsumi FX400, Sony 55E, and just about all non-SCSI
184 double(2X) or better speed drives.
186 If you say Y here, the CD-ROM drive will be identified at boot time
187 along with other IDE devices, as "hdb" or "hdc", or something
188 similar (check the boot messages with dmesg). If this is your only
189 CD-ROM drive, you can say N to all other CD-ROM options, but be sure
190 to say Y or M to "ISO 9660 CD-ROM file system support".
192 To compile this driver as a module, choose M here: the
193 module will be called ide-cd.

196 bool "Verbose error logging for IDE/ATAPI CDROM driver" if EMBEDDED
197 depends on BLK_DEV_IDECD
200 Turn this on to have the driver print out the meanings of the
201 ATAPI error codes. This will use up additional 8kB of kernel-space
204 config BLK_DEV_IDETAPE
205 tristate "Include IDE/ATAPI TAPE support"
207 If you have an IDE tape drive using the ATAPI protocol, say Y.
208 ATAPI is a newer protocol used by IDE tape and CD-ROM drives,
209 similar to the SCSI protocol. If you have an SCSI tape drive
210 however, you can say N here.
212 You should also say Y if you have an OnStream DI-30 tape drive; this
213 will not work with the SCSI protocol, until there is support for the
214 SC-30 and SC-50 versions.
216 If you say Y here, the tape drive will be identified at boot time
217 along with other IDE devices, as "hdb" or "hdc", or something
218 similar, and will be mapped to a character device such as "ht0"
219 (check the boot messages with dmesg). Be sure to consult the
220 <file:drivers/ide/ide-tape.c> and <file:Documentation/ide/ide.txt>
221 files for usage information.
223 To compile this driver as a module, choose M here: the
224 module will be called ide-tape.
226 config BLK_DEV_IDEFLOPPY
227 tristate "Include IDE/ATAPI FLOPPY support"
229 If you have an IDE floppy drive which uses the ATAPI protocol,
230 answer Y. ATAPI is a newer protocol used by IDE CD-ROM/tape/floppy
231 drives, similar to the SCSI protocol.
233 The LS-120 and the IDE/ATAPI Iomega ZIP drive are also supported by
234 this driver. For information about jumper settings and the question
235 of when a ZIP drive uses a partition table, see
236 <http://www.win.tue.nl/~aeb/linux/zip/zip-1.html>.
237 (ATAPI PD-CD/CDR drives are not supported by this driver; support
238 for PD-CD/CDR drives is available if you answer Y to
239 "SCSI emulation support", below).
241 If you say Y here, the FLOPPY drive will be identified along with
242 other IDE devices, as "hdb" or "hdc", or something similar (check
243 the boot messages with dmesg).
245 To compile this driver as a module, choose M here: the
246 module will be called ide-floppy.
248 config BLK_DEV_IDESCSI
249 tristate "SCSI emulation support"
252 WARNING: ide-scsi is no longer needed for cd writing applications!
253 The 2.6 kernel supports direct writing to ide-cd, which eliminates
254 the need for ide-scsi + the entire scsi stack just for writing a
255 cd. The new method is more efficient in every way.
257 This will provide SCSI host adapter emulation for IDE ATAPI devices,
258 and will allow you to use a SCSI device driver instead of a native
261 This is useful if you have an ATAPI device for which no native
262 driver has been written (for example, an ATAPI PD-CD drive);
263 you can then use this emulation together with an appropriate SCSI
264 device driver. In order to do this, say Y here and to "SCSI support"
265 and "SCSI generic support", below. You must then provide the kernel
266 command line "hdx=ide-scsi" (try "man bootparam" or see the
267 documentation of your boot loader (lilo or loadlin) about how to
268 pass options to the kernel at boot time) for devices if you want the
269 native EIDE sub-drivers to skip over the native support, so that
270 this SCSI emulation can be used instead.
272 Note that this option does NOT allow you to attach SCSI devices to a
273 box that doesn't have a SCSI host adapter installed.
275 If both this SCSI emulation and native ATAPI support are compiled
276 into the kernel, the native support will be used.
278 config BLK_DEV_IDEACPI
279 bool "IDE ACPI support"
282 Implement ACPI support for generic IDE devices. On modern
283 machines ACPI support is required to properly handle ACPI S3 states.
285 config IDE_TASK_IOCTL
286 bool "IDE Taskfile Access"
288 This is a direct raw access to the media. It is a complex but
289 elegant solution to test and validate the domain of the hardware and
290 perform below the driver data recovery if needed. This is the most
291 basic form of media-forensics.
293 If you are unsure, say N here.
296 bool "legacy /proc/ide/ support"
297 depends on IDE && PROC_FS
300 This option enables support for the various files in
301 /proc/ide. In Linux 2.6 this has been superseded by
302 files in sysfs but many legacy applications rely on this.

328 "SiS" chipset. Unfortunately, it has a number of rather nasty
329 design flaws that can cause severe data corruption under many common

331 detect and correct the problems under Linux. This option also
332 enables access to the secondary IDE ports in some CMD640 based
335 This driver will work automatically in PCI based systems (most new
336 systems have PCI slots). But if your system uses VESA local bus
337 (VLB) instead of PCI, you must also supply a kernel boot parameter
338 to enable the CMD640 bugfix/support: "ide0=cmd640_vlb". (Try "man
339 bootparam" or see the documentation of your boot loader about how to
340 pass options to the kernel.)
342 The CMD640 chip is also used on add-in cards by Acculogic, and on

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

1062 bool "Old hard disk (MFM/RLL/IDE) driver"
1064 There are two drivers for MFM/RLL/IDE hard disks. Most people use
1065 the newer enhanced driver, but this old one is still around for two
1066 reasons. Some older systems have strange timing problems and seem to
1067 work only with the old driver (which itself does not work with some
1068 newer systems). The other reason is that the old driver is smaller,
1069 since it lacks the enhanced functionality of the new one. This makes
1070 it a good choice for systems with very tight memory restrictions, or
1071 for systems with only older MFM/RLL/ESDI drives. Choosing the old
1072 driver can save 13 KB or so of kernel memory.
1074 If you want to use this driver together with the new one you have
1075 to use "hda=noprobe hdb=noprobe" kernel parameters to prevent the new
1076 driver from probing the primary interface.
1078 If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1079 instead of this one. For more detailed information, read the
