The most common 14 cases are IDE hard drives and ATAPI CD-ROM drives. 15 16 If your system is pure SCSI and doesn't use these interfaces, you 17 can say N here. 18 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. 23 24 AT Attachment (ATA) is the superset of the IDE specifications. 25 ST506 was also called ATA-1. 26 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. 34 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. 37 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. 45 46 To compile this driver as a module, choose M here: the 47 module will be called ide. 48 49 For further information, please read <file:Documentation/ide.txt>. 50 51 If unsure, say Y. 52 53if IDE 54 55config IDE_MAX_HWIFS 56 int "Max IDE interfaces" 57 depends on ALPHA || SUPERH || IA64 58 default 4 59 help 60 This is the maximum number of IDE hardware interfaces that will 61 be supported by the driver. Make sure it is at least as high as 62 the number of IDE interfaces in your system. 63 64config BLK_DEV_IDE 65 tristate "Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support" 66 ---help--- 67 If you say Y here, you will use the full-featured IDE driver to 68 control up to ten ATA/IDE interfaces, each being able to serve a 69 "master" and a "slave" device, for a total of up to twenty ATA/IDE 70 disk/cdrom/tape/floppy drives. 71 72 Useful information about large (>540 MB) IDE disks, multiple 73 interfaces, what to do if ATA/IDE devices are not automatically 74 detected, sound card ATA/IDE ports, module support, and other 75 topics, is contained in <file:Documentation/ide.txt>. For detailed 76 information about hard drives, consult the Disk-HOWTO and the 77 Multi-Disk-HOWTO, available from 78 <http://www.tldp.org/docs.html#howto>. 79 80 To fine-tune ATA/IDE drive/interface parameters for improved 81 performance, look for the hdparm package at 82 <ftp://ibiblio.org/pub/Linux/system/hardware/>. 83 84 To compile this driver as a module, choose M here and read 85 <file:Documentation/ide.txt>. The module will be called ide-mod. 86 Do not compile this driver as a module if your root file system (the 87 one containing the directory /) is located on an IDE device. 88 89 If you have one or more IDE drives, say Y or M here. If your system 90 has no IDE drives, or if memory requirements are really tight, you 91 could say N here, and select the "Old hard disk driver" below 92 instead to save about 13 KB of memory in the kernel. 93 94if BLK_DEV_IDE 95 96comment "Please see Documentation/ide.txt for help/info on IDE drives" 97 98config BLK_DEV_IDE_SATA 99 bool "Support for SATA (deprecated; conflicts with libata SATA driver)" 100 default n 101 ---help--- 102 There are two drivers for Serial ATA controllers. 103 104 The main driver, "libata", exists inside the SCSI subsystem 105 and supports most modern SATA controllers. 106 107 The IDE driver (which you are currently configuring) supports 108 a few first-generation SATA controllers. 109 110 In order to eliminate conflicts between the two subsystems, 111 this config option enables the IDE driver's SATA support. 112 Normally this is disabled, as it is preferred that libata 113 supports SATA controllers, and this (IDE) driver supports 114 PATA controllers. 115 116 If unsure, say N. 117 118config BLK_DEV_HD_IDE 119 bool "Use old disk-only driver on primary interface" 120 depends on (X86 || SH_MPC1211) 121 ---help--- 122 There are two drivers for MFM/RLL/IDE disks. Most people use just 123 the new enhanced driver by itself. This option however installs the 124 old hard disk driver to control the primary IDE/disk interface in 125 the system, leaving the new enhanced IDE driver to take care of only 126 the 2nd/3rd/4th IDE interfaces. Doing this will prevent you from 127 having an IDE/ATAPI CD-ROM or tape drive connected to the primary 128 IDE interface. Choosing this option may be useful for older systems 129 which have MFM/RLL/ESDI controller+drives at the primary port 130 address (0x1f0), along with IDE drives at the secondary/3rd/4th port 131 addresses. 132 133 Normally, just say N here; you will then use the new driver for all 134 4 interfaces. 135 136config BLK_DEV_IDEDISK 137 tristate "Include IDE/ATA-2 DISK support" 138 ---help--- 139 This will include enhanced support for MFM/RLL/IDE hard disks. If 140 you have a MFM/RLL/IDE disk, and there is no special reason to use 141 the old hard disk driver instead, say Y. If you have an SCSI-only 142 system, you can say N here. 143 144 To compile this driver as a module, choose M here: the 145 module will be called ide-disk. 146 Do not compile this driver as a module if your root file system 147 (the one containing the directory /) is located on the IDE disk. 148 149 If unsure, say Y. 150 151config IDEDISK_MULTI_MODE 152 bool "Use multi-mode by default" 153 help 154 If you get this error, try to say Y here: 155 156 hda: set_multmode: status=0x51 { DriveReady SeekComplete Error } 157 hda: set_multmode: error=0x04 { DriveStatusError } 158 159 If in doubt, say N. 160 161config BLK_DEV_IDECS 162 tristate "PCMCIA IDE support" 163 depends on PCMCIA 164 help 165 Support for Compact Flash cards, outboard IDE disks, tape drives, 166 and CD-ROM drives connected through a PCMCIA card. 167 168config BLK_DEV_IDECD 169 tristate "Include IDE/ATAPI CDROM support" 170 ---help--- 171 If you have a CD-ROM drive using the ATAPI protocol, say Y. ATAPI is 172 a newer protocol used by IDE CD-ROM and TAPE drives, similar to the 173 SCSI protocol. Most new CD-ROM drives use ATAPI, including the 174 NEC-260, Mitsumi FX400, Sony 55E, and just about all non-SCSI 175 double(2X) or better speed drives. 176 177 If you say Y here, the CD-ROM drive will be identified at boot time 178 along with other IDE devices, as "hdb" or "hdc", or something 179 similar (check the boot messages with dmesg). If this is your only 180 CD-ROM drive, you can say N to all other CD-ROM options, but be sure 181 to say Y or M to "ISO 9660 CD-ROM file system support". 182 183 Note that older versions of LILO (LInux LOader) cannot properly deal 184 with IDE/ATAPI CD-ROMs, so install LILO 16 or higher, available from 185 <http://lilo.go.dyndns.org/>. 186 187 To compile this driver as a module, choose M here: the 188 module will be called ide-cd. 189 190config BLK_DEV_IDETAPE 191 tristate "Include IDE/ATAPI TAPE support (EXPERIMENTAL)" 192 depends on EXPERIMENTAL 193 help 194 If you have an IDE tape drive using the ATAPI protocol, say Y. 195 ATAPI is a newer protocol used by IDE tape and CD-ROM drives, 196 similar to the SCSI protocol. If you have an SCSI tape drive 197 however, you can say N here. 198 199 You should also say Y if you have an OnStream DI-30 tape drive; this 200 will not work with the SCSI protocol, until there is support for the 201 SC-30 and SC-50 versions. 202 203 If you say Y here, the tape drive will be identified at boot time 204 along with other IDE devices, as "hdb" or "hdc", or something 205 similar, and will be mapped to a character device such as "ht0" 206 (check the boot messages with dmesg).

ATAPI is a newer protocol used by IDE CD-ROM/tape/floppy 218 drives, similar to the SCSI protocol. 219 220 The LS-120 and the IDE/ATAPI Iomega ZIP drive are also supported by 221 this driver. For information about jumper settings and the question 222 of when a ZIP drive uses a partition table, see 223 <http://www.win.tue.nl/~aeb/linux/zip/zip-1.html>. 224 (ATAPI PD-CD/CDR drives are not supported by this driver; support 225 for PD-CD/CDR drives is available if you answer Y to 226 "SCSI emulation support", below). 227 228 If you say Y here, the FLOPPY drive will be identified along with 229 other IDE devices, as "hdb" or "hdc", or something similar (check 230 the boot messages with dmesg). 231 232 To compile this driver as a module, choose M here: the 233 module will be called ide-floppy. 234 235config BLK_DEV_IDESCSI 236 tristate "SCSI emulation support" 237 depends on SCSI 238 ---help--- 239 WARNING: ide-scsi is no longer needed for cd writing applications! 240 The 2.6 kernel supports direct writing to ide-cd, which eliminates 241 the need for ide-scsi + the entire scsi stack just for writing a 242 cd. The new method is more efficient in every way. 243 244 This will provide SCSI host adapter emulation for IDE ATAPI devices, 245 and will allow you to use a SCSI device driver instead of a native 246 ATAPI driver. 247 248 This is useful if you have an ATAPI device for which no native 249 driver has been written (for example, an ATAPI PD-CD drive); 250 you can then use this emulation together with an appropriate SCSI 251 device driver. In order to do this, say Y here and to "SCSI support" 252 and "SCSI generic support", below. You must then provide the kernel 253 command line "hdx=ide-scsi" (try "man bootparam" or see the 254 documentation of your boot loader (lilo or loadlin) about how to 255 pass options to the kernel at boot time) for devices if you want the 256 native EIDE sub-drivers to skip over the native support, so that 257 this SCSI emulation can be used instead. 258 259 Note that this option does NOT allow you to attach SCSI devices to a 260 box that doesn't have a SCSI host adapter installed. 261 262 If both this SCSI emulation and native ATAPI support are compiled 263 into the kernel, the native support will be used. 264 265config IDE_TASK_IOCTL 266 bool "IDE Taskfile Access" 267 help 268 This is a direct raw access to the media. It is a complex but 269 elegant solution to test and validate the domain of the hardware and 270 perform below the driver data recovery if needed. This is the most 271 basic form of media-forensics. 272 273 If you are unsure, say N here. 274 275comment "IDE chipset support/bugfixes" 276 277config IDE_GENERIC 278 tristate "generic/default IDE chipset support" 279 default y 280 help 281 If unsure, say Y. 282 283config BLK_DEV_CMD640 284 bool "CMD640 chipset bugfix/support" 285 depends on X86 286 ---help--- 287 The CMD-Technologies CMD640 IDE chip is used on many common 486 and 288 Pentium motherboards, usually in combination with a "Neptune" or 289 "SiS" chipset. Unfortunately, it has a number of rather nasty 290 design flaws that can cause severe data corruption under many common 291 conditions. Say Y here to include code which tries to automatically 292 detect and correct the problems under Linux. This option also 293 enables access to the secondary IDE ports in some CMD640 based 294 systems. 295 296 This driver will work automatically in PCI based systems (most new 297 systems have PCI slots). But if your system uses VESA local bus 298 (VLB) instead of PCI, you must also supply a kernel boot parameter 299 to enable the CMD640 bugfix/support: "ide0=cmd640_vlb". (Try "man 300 bootparam" or see the documentation of your boot loader about how to 301 pass options to the kernel.) 302 303 The CMD640 chip is also used on add-in cards by Acculogic, and on 304 the "CSA-6400E PCI to IDE controller" that some people have.
