The most common 16 cases are IDE hard drives and ATAPI CD-ROM drives. 17 18 If your system is pure SCSI and doesn't use these interfaces, you 19 can say N here. 20 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. 25 26 AT Attachment (ATA) is the superset of the IDE specifications. 27 ST506 was also called ATA-1. 28 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. 36 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. 39 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. 47 48 To compile this driver as a module, choose M here: the 49 module will be called ide. 50 51 For further information, please read <file:Documentation/ide.txt>. 52 53 If unsure, say Y. 54 55if IDE 56 57config IDE_MAX_HWIFS 58 int "Max IDE interfaces" 59 depends on ALPHA || SUPERH || IA64 60 default 4 61 help 62 This is the maximum number of IDE hardware interfaces that will 63 be supported by the driver. Make sure it is at least as high as 64 the number of IDE interfaces in your system. 65 66config BLK_DEV_IDE 67 tristate "Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support" 68 ---help--- 69 If you say Y here, you will use the full-featured IDE driver to 70 control up to ten ATA/IDE interfaces, each being able to serve a 71 "master" and a "slave" device, for a total of up to twenty ATA/IDE 72 disk/cdrom/tape/floppy drives. 73 74 Useful information about large (>540 MB) IDE disks, multiple 75 interfaces, what to do if ATA/IDE devices are not automatically 76 detected, sound card ATA/IDE ports, module support, and other 77 topics, is contained in <file:Documentation/ide.txt>. For detailed 78 information about hard drives, consult the Disk-HOWTO and the 79 Multi-Disk-HOWTO, available from 80 <http://www.tldp.org/docs.html#howto>. 81 82 To fine-tune ATA/IDE drive/interface parameters for improved 83 performance, look for the hdparm package at 84 <ftp://ibiblio.org/pub/Linux/system/hardware/>. 85 86 To compile this driver as a module, choose M here and read 87 <file:Documentation/ide.txt>. The module will be called ide-mod. 88 Do not compile this driver as a module if your root file system (the 89 one containing the directory /) is located on an IDE device. 90 91 If you have one or more IDE drives, say Y or M here. If your system 92 has no IDE drives, or if memory requirements are really tight, you 93 could say N here, and select the "Old hard disk driver" below 94 instead to save about 13 KB of memory in the kernel. 95 96if BLK_DEV_IDE 97 98comment "Please see Documentation/ide.txt for help/info on IDE drives" 99 100config BLK_DEV_IDE_SATA 101 bool "Support for SATA (deprecated; conflicts with libata SATA driver)" 102 default n 103 ---help--- 104 There are two drivers for Serial ATA controllers. 105 106 The main driver, "libata", exists inside the SCSI subsystem 107 and supports most modern SATA controllers. 108 109 The IDE driver (which you are currently configuring) supports 110 a few first-generation SATA controllers. 111 112 In order to eliminate conflicts between the two subsystems, 113 this config option enables the IDE driver's SATA support. 114 Normally this is disabled, as it is preferred that libata 115 supports SATA controllers, and this (IDE) driver supports 116 PATA controllers. 117 118 If unsure, say N. 119 120config BLK_DEV_HD_IDE 121 bool "Use old disk-only driver on primary interface" 122 depends on (X86 || SH_MPC1211) 123 ---help--- 124 There are two drivers for MFM/RLL/IDE disks. Most people use just 125 the new enhanced driver by itself. This option however installs the 126 old hard disk driver to control the primary IDE/disk interface in 127 the system, leaving the new enhanced IDE driver to take care of only 128 the 2nd/3rd/4th IDE interfaces. Doing this will prevent you from 129 having an IDE/ATAPI CD-ROM or tape drive connected to the primary 130 IDE interface. Choosing this option may be useful for older systems 131 which have MFM/RLL/ESDI controller+drives at the primary port 132 address (0x1f0), along with IDE drives at the secondary/3rd/4th port 133 addresses. 134 135 Normally, just say N here; you will then use the new driver for all 136 4 interfaces. 137 138config BLK_DEV_IDEDISK 139 tristate "Include IDE/ATA-2 DISK support" 140 ---help--- 141 This will include enhanced support for MFM/RLL/IDE hard disks. If 142 you have a MFM/RLL/IDE disk, and there is no special reason to use 143 the old hard disk driver instead, say Y. If you have an SCSI-only 144 system, you can say N here. 145 146 To compile this driver as a module, choose M here: the 147 module will be called ide-disk. 148 Do not compile this driver as a module if your root file system 149 (the one containing the directory /) is located on the IDE disk. 150 151 If unsure, say Y. 152 153config IDEDISK_MULTI_MODE 154 bool "Use multi-mode by default" 155 help 156 If you get this error, try to say Y here: 157 158 hda: set_multmode: status=0x51 { DriveReady SeekComplete Error } 159 hda: set_multmode: error=0x04 { DriveStatusError } 160 161 If in doubt, say N. 162 163config BLK_DEV_IDECS 164 tristate "PCMCIA IDE support" 165 depends on PCMCIA 166 help 167 Support for Compact Flash cards, outboard IDE disks, tape drives, 168 and CD-ROM drives connected through a PCMCIA card. 169 170config BLK_DEV_IDECD 171 tristate "Include IDE/ATAPI CDROM support" 172 ---help--- 173 If you have a CD-ROM drive using the ATAPI protocol, say Y. ATAPI is 174 a newer protocol used by IDE CD-ROM and TAPE drives, similar to the 175 SCSI protocol. Most new CD-ROM drives use ATAPI, including the 176 NEC-260, Mitsumi FX400, Sony 55E, and just about all non-SCSI 177 double(2X) or better speed drives. 178 179 If you say Y here, the CD-ROM drive will be identified at boot time 180 along with other IDE devices, as "hdb" or "hdc", or something 181 similar (check the boot messages with dmesg). If this is your only 182 CD-ROM drive, you can say N to all other CD-ROM options, but be sure 183 to say Y or M to "ISO 9660 CD-ROM file system support". 184 185 Note that older versions of LILO (LInux LOader) cannot properly deal 186 with IDE/ATAPI CD-ROMs, so install LILO 16 or higher, available from 187 <http://lilo.go.dyndns.org/>. 188 189 To compile this driver as a module, choose M here: the 190 module will be called ide-cd. 191 192config BLK_DEV_IDETAPE 193 tristate "Include IDE/ATAPI TAPE support (EXPERIMENTAL)" 194 depends on EXPERIMENTAL 195 help 196 If you have an IDE tape drive using the ATAPI protocol, say Y. 197 ATAPI is a newer protocol used by IDE tape and CD-ROM drives, 198 similar to the SCSI protocol. If you have an SCSI tape drive 199 however, you can say N here. 200 201 You should also say Y if you have an OnStream DI-30 tape drive; this 202 will not work with the SCSI protocol, until there is support for the 203 SC-30 and SC-50 versions. 204 205 If you say Y here, the tape drive will be identified at boot time 206 along with other IDE devices, as "hdb" or "hdc", or something 207 similar, and will be mapped to a character device such as "ht0" 208 (check the boot messages with dmesg).

ATAPI is a newer protocol used by IDE CD-ROM/tape/floppy 220 drives, similar to the SCSI protocol. 221 222 The LS-120 and the IDE/ATAPI Iomega ZIP drive are also supported by 223 this driver. For information about jumper settings and the question 224 of when a ZIP drive uses a partition table, see 225 <http://www.win.tue.nl/~aeb/linux/zip/zip-1.html>. 226 (ATAPI PD-CD/CDR drives are not supported by this driver; support 227 for PD-CD/CDR drives is available if you answer Y to 228 "SCSI emulation support", below). 229 230 If you say Y here, the FLOPPY drive will be identified along with 231 other IDE devices, as "hdb" or "hdc", or something similar (check 232 the boot messages with dmesg). 233 234 To compile this driver as a module, choose M here: the 235 module will be called ide-floppy. 236 237config BLK_DEV_IDESCSI 238 tristate "SCSI emulation support" 239 depends on SCSI 240 ---help--- 241 WARNING: ide-scsi is no longer needed for cd writing applications! 242 The 2.6 kernel supports direct writing to ide-cd, which eliminates 243 the need for ide-scsi + the entire scsi stack just for writing a 244 cd. The new method is more efficient in every way. 245 246 This will provide SCSI host adapter emulation for IDE ATAPI devices, 247 and will allow you to use a SCSI device driver instead of a native 248 ATAPI driver. 249 250 This is useful if you have an ATAPI device for which no native 251 driver has been written (for example, an ATAPI PD-CD drive); 252 you can then use this emulation together with an appropriate SCSI 253 device driver. In order to do this, say Y here and to "SCSI support" 254 and "SCSI generic support", below. You must then provide the kernel 255 command line "hdx=ide-scsi" (try "man bootparam" or see the 256 documentation of your boot loader (lilo or loadlin) about how to 257 pass options to the kernel at boot time) for devices if you want the 258 native EIDE sub-drivers to skip over the native support, so that 259 this SCSI emulation can be used instead. 260 261 Note that this option does NOT allow you to attach SCSI devices to a 262 box that doesn't have a SCSI host adapter installed. 263 264 If both this SCSI emulation and native ATAPI support are compiled 265 into the kernel, the native support will be used. 266 267config IDE_TASK_IOCTL 268 bool "IDE Taskfile Access" 269 help 270 This is a direct raw access to the media. It is a complex but 271 elegant solution to test and validate the domain of the hardware and 272 perform below the driver data recovery if needed. This is the most 273 basic form of media-forensics. 274 275 If you are unsure, say N here. 276 277comment "IDE chipset support/bugfixes" 278 279config IDE_GENERIC 280 tristate "generic/default IDE chipset support" 281 default y 282 help 283 If unsure, say Y. 284 285config BLK_DEV_CMD640 286 bool "CMD640 chipset bugfix/support" 287 depends on X86 288 ---help--- 289 The CMD-Technologies CMD640 IDE chip is used on many common 486 and 290 Pentium motherboards, usually in combination with a "Neptune" or 291 "SiS" chipset. Unfortunately, it has a number of rather nasty 292 design flaws that can cause severe data corruption under many common 293 conditions. Say Y here to include code which tries to automatically 294 detect and correct the problems under Linux. This option also 295 enables access to the secondary IDE ports in some CMD640 based 296 systems. 297 298 This driver will work automatically in PCI based systems (most new 299 systems have PCI slots). But if your system uses VESA local bus 300 (VLB) instead of PCI, you must also supply a kernel boot parameter 301 to enable the CMD640 bugfix/support: "ide0=cmd640_vlb". (Try "man 302 bootparam" or see the documentation of your boot loader about how to 303 pass options to the kernel.) 304 305 The CMD640 chip is also used on add-in cards by Acculogic, and on 306 the "CSA-6400E PCI to IDE controller" that some people have.
