10 tristate "ATA/ATAPI/MFM/RLL support"
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.

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/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/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.

107 config BLK_DEV_IDE_SATA
108 bool "Support for SATA (deprecated; conflicts with libata SATA driver)"
111 There are two drivers for Serial ATA controllers.
113 The main driver, "libata", uses the SCSI subsystem
114 and supports most modern SATA controllers. In order to use it
115 you may take a look at "Serial ATA (prod) and Parallel ATA
116 (experimental) drivers".
118 The IDE driver (which you are currently configuring) supports
119 a few first-generation SATA controllers.
121 In order to eliminate conflicts between the two subsystems,
122 this config option enables the IDE driver's SATA support.
123 Normally this is disabled, as it is preferred that libata
124 supports SATA controllers, and this (IDE) driver supports
129 config BLK_DEV_IDEDISK
130 tristate "Include IDE/ATA-2 DISK support"
132 This will include enhanced support for MFM/RLL/IDE hard disks. If
133 you have a MFM/RLL/IDE disk, and there is no special reason to use
134 the old hard disk driver instead, say Y. If you have an SCSI-only
135 system, you can say N here.
137 To compile this driver as a module, choose M here: the
138 module will be called ide-disk.
139 Do not compile this driver as a module if your root file system
140 (the one containing the directory /) is located on the IDE disk.
144 config IDEDISK_MULTI_MODE
145 bool "Use multiple sector mode for Programmed Input/Output by default"
147 This setting is irrelevant for most IDE disks, with direct memory
148 access, to which multiple sector mode does not apply. Multiple sector
149 mode is a feature of most modern IDE hard drives, permitting the
150 transfer of multiple sectors per Programmed Input/Output interrupt,
151 rather than the usual one sector per interrupt. When this feature is
152 enabled, it can reduce operating system overhead for disk Programmed
153 Input/Output. On some systems, it also can increase the data
154 throughput of Programmed Input/Output. Some drives, however, seemed
155 to run slower with multiple sector mode enabled. Some drives claimed
156 to support multiple sector mode, but lost data at some settings.
157 Under rare circumstances, such failures could result in massive
158 filesystem corruption.
160 If you get the following error, try to say Y here:
162 hda: set_multmode: status=0x51 { DriveReady SeekComplete Error }
163 hda: set_multmode: error=0x04 { DriveStatusError }

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

201 depends on BLK_DEV_IDECD
204 Turn this on to have the driver print out the meanings of the
205 ATAPI error codes. This will use up additional 8kB of kernel-space
208 config BLK_DEV_IDETAPE
209 tristate "Include IDE/ATAPI TAPE support"
212 If you have an IDE tape drive using the ATAPI protocol, say Y.
213 ATAPI is a newer protocol used by IDE tape and CD-ROM drives,
214 similar to the SCSI protocol. If you have an SCSI tape drive
215 however, you can say N here.
217 You should also say Y if you have an OnStream DI-30 tape drive; this
218 will not work with the SCSI protocol, until there is support for the
219 SC-30 and SC-50 versions.
221 If you say Y here, the tape drive will be identified at boot time
222 along with other IDE devices, as "hdb" or "hdc", or something
223 similar, and will be mapped to a character device such as "ht0"
224 (check the boot messages with dmesg). Be sure to consult the
225 <file:drivers/ide/ide-tape.c> and <file:Documentation/ide/ide.txt>
226 files for usage information.
228 To compile this driver as a module, choose M here: the
229 module will be called ide-tape.
231 config BLK_DEV_IDEFLOPPY
232 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"
259 WARNING: ide-scsi is no longer needed for cd writing applications!
260 The 2.6 kernel supports direct writing to ide-cd, which eliminates
261 the need for ide-scsi + the entire scsi stack just for writing a
262 cd. The new method is more efficient in every way.
264 This will provide SCSI host adapter emulation for IDE ATAPI devices,
265 and will allow you to use a SCSI device driver instead of a native
268 This is useful if you have an ATAPI device for which no native
269 driver has been written (for example, an ATAPI PD-CD drive);
270 you can then use this emulation together with an appropriate SCSI
271 device driver. In order to do this, say Y here and to "SCSI support"
272 and "SCSI generic support", below. You must then provide the kernel
273 command line "hdx=ide-scsi" (try "man bootparam" or see the
274 documentation of your boot loader (lilo or loadlin) about how to
275 pass options to the kernel at boot time) for devices if you want the
276 native EIDE sub-drivers to skip over the native support, so that
277 this SCSI emulation can be used instead.
279 Note that this option does NOT allow you to attach SCSI devices to a
280 box that doesn't have a SCSI host adapter installed.
282 If both this SCSI emulation and native ATAPI support are compiled
283 into the kernel, the native support will be used.
285 config BLK_DEV_IDEACPI
286 bool "IDE ACPI support"
289 Implement ACPI support for generic IDE devices. On modern
290 machines ACPI support is required to properly handle ACPI S3 states.
292 config IDE_TASK_IOCTL
293 bool "IDE Taskfile Access"
295 This is a direct raw access to the media. It is a complex but
296 elegant solution to test and validate the domain of the hardware and
297 perform below the driver data recovery if needed. This is the most
298 basic form of media-forensics.
300 If you are unsure, say N here.
303 bool "legacy /proc/ide/ support"
304 depends on IDE && PROC_FS
307 This option enables support for the various files in
308 /proc/ide. In Linux 2.6 this has been superseded by
309 files in sysfs but many legacy applications rely on this.

343 systems have PCI slots). But if your system uses VESA local bus
344 (VLB) instead of PCI, you must also supply a kernel boot parameter
345 to enable the CMD640 bugfix/support: "cmd640.probe_vlb". (Try "man
346 bootparam" or see the documentation of your boot loader about how to
347 pass options to the kernel.)

1043 There are two drivers for MFM/RLL/IDE hard disks. Most people use
1044 the newer enhanced driver, but this old one is still around for two
1045 reasons. Some older systems have strange timing problems and seem to
1046 work only with the old driver (which itself does not work with some
1047 newer systems). The other reason is that the old driver is smaller,
1048 since it lacks the enhanced functionality of the new one. This makes
1049 it a good choice for systems with very tight memory restrictions, or
1050 for systems with only older MFM/RLL/ESDI drives. Choosing the old
1051 driver can save 13 KB or so of kernel memory.
1053 If you want to use this driver together with the new one you have
1054 to use "hda=noprobe hdb=noprobe" kernel parameters to prevent the new
1055 driver from probing the primary interface.
1057 If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1058 instead of this one. For more detailed information, read the
1059 Disk-HOWTO, available from
