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 || EMBEDDED 60 range 1 10 61 default 4 62 help 63 This is the maximum number of IDE hardware interfaces that will 64 be supported by the driver.

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>. 82 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/>. 86 87 To compile this driver as a module, choose M here and read 88 <file:Documentation/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. 91 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. 96 97if BLK_DEV_IDE 98 99comment "Please see Documentation/ide.txt for help/info on IDE drives" 100 101config BLK_DEV_IDE_SATA 102 bool "Support for SATA (deprecated; conflicts with libata SATA driver)" 103 default n 104 ---help--- 105 There are two drivers for Serial ATA controllers. 106 107 The main driver, "libata", uses the SCSI subsystem 108 and supports most modern SATA controllers. In order to use it 109 you may take a look at "Serial ATA (prod) and Parallel ATA 110 (experimental) drivers". 111 112 The IDE driver (which you are currently configuring) supports 113 a few first-generation SATA controllers. 114 115 In order to eliminate conflicts between the two subsystems, 116 this config option enables the IDE driver's SATA support. 117 Normally this is disabled, as it is preferred that libata 118 supports SATA controllers, and this (IDE) driver supports 119 PATA controllers. 120 121 If unsure, say N. 122 123config BLK_DEV_HD_IDE 124 bool "Use old disk-only driver on primary interface" 125 depends on (X86 || SH_MPC1211) 126 ---help--- 127 There are two drivers for MFM/RLL/IDE disks. Most people use just 128 the new enhanced driver by itself. This option however installs the 129 old hard disk driver to control the primary IDE/disk interface in 130 the system, leaving the new enhanced IDE driver to take care of only 131 the 2nd/3rd/4th IDE interfaces. Doing this will prevent you from 132 having an IDE/ATAPI CD-ROM or tape drive connected to the primary 133 IDE interface. Choosing this option may be useful for older systems 134 which have MFM/RLL/ESDI controller+drives at the primary port 135 address (0x1f0), along with IDE drives at the secondary/3rd/4th port 136 addresses. 137 138 Normally, just say N here; you will then use the new driver for all 139 4 interfaces. 140 141config BLK_DEV_IDEDISK 142 tristate "Include IDE/ATA-2 DISK support" 143 ---help--- 144 This will include enhanced support for MFM/RLL/IDE hard disks. If 145 you have a MFM/RLL/IDE disk, and there is no special reason to use 146 the old hard disk driver instead, say Y. If you have an SCSI-only 147 system, you can say N here. 148 149 To compile this driver as a module, choose M here: the 150 module will be called ide-disk. 151 Do not compile this driver as a module if your root file system 152 (the one containing the directory /) is located on the IDE disk. 153 154 If unsure, say Y. 155 156config IDEDISK_MULTI_MODE 157 bool "Use multi-mode by default" 158 help 159 If you get this error, try to say Y here: 160 161 hda: set_multmode: status=0x51 { DriveReady SeekComplete Error } 162 hda: set_multmode: error=0x04 { DriveStatusError } 163 164 If in doubt, say N. 165 166config BLK_DEV_IDECS 167 tristate "PCMCIA IDE support" 168 depends on PCMCIA 169 help 170 Support for Compact Flash cards, outboard IDE disks, tape drives, 171 and CD-ROM drives connected through a PCMCIA card. 172 173config BLK_DEV_DELKIN 174 tristate "Cardbus IDE support (Delkin/ASKA/Workbit)" 175 depends on CARDBUS && PCI 176 help 177 Support for Delkin, ASKA, and Workbit Cardbus CompactFlash 178 Adapters.

ATAPI is 184 a newer protocol used by IDE CD-ROM and TAPE drives, similar to the 185 SCSI protocol. Most new CD-ROM drives use ATAPI, including the 186 NEC-260, Mitsumi FX400, Sony 55E, and just about all non-SCSI 187 double(2X) or better speed drives. 188 189 If you say Y here, the CD-ROM drive will be identified at boot time 190 along with other IDE devices, as "hdb" or "hdc", or something 191 similar (check the boot messages with dmesg). If this is your only 192 CD-ROM drive, you can say N to all other CD-ROM options, but be sure 193 to say Y or M to "ISO 9660 CD-ROM file system support". 194 195 Note that older versions of LILO (LInux LOader) cannot properly deal 196 with IDE/ATAPI CD-ROMs, so install LILO 16 or higher, available from 197 <http://lilo.go.dyndns.org/>. 198 199 To compile this driver as a module, choose M here: the 200 module will be called ide-cd. 201 202config BLK_DEV_IDETAPE 203 tristate "Include IDE/ATAPI TAPE support (EXPERIMENTAL)" 204 depends on EXPERIMENTAL 205 help 206 If you have an IDE tape drive using the ATAPI protocol, say Y. 207 ATAPI is a newer protocol used by IDE tape and CD-ROM drives, 208 similar to the SCSI protocol. If you have an SCSI tape drive 209 however, you can say N here. 210 211 You should also say Y if you have an OnStream DI-30 tape drive; this 212 will not work with the SCSI protocol, until there is support for the 213 SC-30 and SC-50 versions. 214 215 If you say Y here, the tape drive will be identified at boot time 216 along with other IDE devices, as "hdb" or "hdc", or something 217 similar, and will be mapped to a character device such as "ht0" 218 (check the boot messages with dmesg).

ATAPI is a newer protocol used by IDE CD-ROM/tape/floppy 230 drives, similar to the SCSI protocol. 231 232 The LS-120 and the IDE/ATAPI Iomega ZIP drive are also supported by 233 this driver. For information about jumper settings and the question 234 of when a ZIP drive uses a partition table, see 235 <http://www.win.tue.nl/~aeb/linux/zip/zip-1.html>. 236 (ATAPI PD-CD/CDR drives are not supported by this driver; support 237 for PD-CD/CDR drives is available if you answer Y to 238 "SCSI emulation support", below). 239 240 If you say Y here, the FLOPPY drive will be identified along with 241 other IDE devices, as "hdb" or "hdc", or something similar (check 242 the boot messages with dmesg). 243 244 To compile this driver as a module, choose M here: the 245 module will be called ide-floppy. 246 247config BLK_DEV_IDESCSI 248 tristate "SCSI emulation support" 249 depends on SCSI 250 ---help--- 251 WARNING: ide-scsi is no longer needed for cd writing applications! 252 The 2.6 kernel supports direct writing to ide-cd, which eliminates 253 the need for ide-scsi + the entire scsi stack just for writing a 254 cd. The new method is more efficient in every way. 255 256 This will provide SCSI host adapter emulation for IDE ATAPI devices, 257 and will allow you to use a SCSI device driver instead of a native 258 ATAPI driver. 259 260 This is useful if you have an ATAPI device for which no native 261 driver has been written (for example, an ATAPI PD-CD drive); 262 you can then use this emulation together with an appropriate SCSI 263 device driver. In order to do this, say Y here and to "SCSI support" 264 and "SCSI generic support", below. You must then provide the kernel 265 command line "hdx=ide-scsi" (try "man bootparam" or see the 266 documentation of your boot loader (lilo or loadlin) about how to 267 pass options to the kernel at boot time) for devices if you want the 268 native EIDE sub-drivers to skip over the native support, so that 269 this SCSI emulation can be used instead. 270 271 Note that this option does NOT allow you to attach SCSI devices to a 272 box that doesn't have a SCSI host adapter installed. 273 274 If both this SCSI emulation and native ATAPI support are compiled 275 into the kernel, the native support will be used. 276 277config BLK_DEV_IDEACPI 278 bool "IDE ACPI support" 279 depends on ACPI 280 ---help--- 281 Implement ACPI support for generic IDE devices.

Unfortunately, it has a number of rather nasty 309 design flaws that can cause severe data corruption under many common 310 conditions. Say Y here to include code which tries to automatically 311 detect and correct the problems under Linux. This option also 312 enables access to the secondary IDE ports in some CMD640 based 313 systems. 314 315 This driver will work automatically in PCI based systems (most new 316 systems have PCI slots). But if your system uses VESA local bus 317 (VLB) instead of PCI, you must also supply a kernel boot parameter 318 to enable the CMD640 bugfix/support: "ide0=cmd640_vlb". (Try "man 319 bootparam" or see the documentation of your boot loader about how to 320 pass options to the kernel.) 321 322 The CMD640 chip is also used on add-in cards by Acculogic, and on 323 the "CSA-6400E PCI to IDE controller" that some people have.
