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 || EMBEDDED 58 range 1 10 59 default 4 60 help 61 This is the maximum number of IDE hardware interfaces that will 62 be supported by the driver. Make sure it is at least as high as 63 the number of IDE interfaces in your system. 64 65config BLK_DEV_IDE 66 tristate "Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support" 67 ---help--- 68 If you say Y here, you will use the full-featured IDE driver to 69 control up to ten ATA/IDE interfaces, each being able to serve a 70 "master" and a "slave" device, for a total of up to twenty ATA/IDE 71 disk/cdrom/tape/floppy drives. 72 73 Useful information about large (>540 MB) IDE disks, multiple 74 interfaces, what to do if ATA/IDE devices are not automatically 75 detected, sound card ATA/IDE ports, module support, and other 76 topics, is contained in <file:Documentation/ide.txt>. For detailed 77 information about hard drives, consult the Disk-HOWTO and the 78 Multi-Disk-HOWTO, available from 79 <http://www.tldp.org/docs.html#howto>. 80 81 To fine-tune ATA/IDE drive/interface parameters for improved 82 performance, look for the hdparm package at 83 <ftp://ibiblio.org/pub/Linux/system/hardware/>. 84 85 To compile this driver as a module, choose M here and read 86 <file:Documentation/ide.txt>. The module will be called ide-mod. 87 Do not compile this driver as a module if your root file system (the 88 one containing the directory /) is located on an IDE device. 89 90 If you have one or more IDE drives, say Y or M here. If your system 91 has no IDE drives, or if memory requirements are really tight, you 92 could say N here, and select the "Old hard disk driver" below 93 instead to save about 13 KB of memory in the kernel. 94 95if BLK_DEV_IDE 96 97comment "Please see Documentation/ide.txt for help/info on IDE drives" 98 99config BLK_DEV_IDE_SATA 100 bool "Support for SATA (deprecated; conflicts with libata SATA driver)" 101 default n 102 ---help--- 103 There are two drivers for Serial ATA controllers. 104 105 The main driver, "libata", uses the SCSI subsystem 106 and supports most modern SATA controllers. In order to use it 107 you may take a look at "Serial ATA (prod) and Parallel ATA 108 (experimental) drivers". 109 110 The IDE driver (which you are currently configuring) supports 111 a few first-generation SATA controllers. 112 113 In order to eliminate conflicts between the two subsystems, 114 this config option enables the IDE driver's SATA support. 115 Normally this is disabled, as it is preferred that libata 116 supports SATA controllers, and this (IDE) driver supports 117 PATA controllers. 118 119 If unsure, say N. 120 121config BLK_DEV_HD_IDE 122 bool "Use old disk-only driver on primary interface" 123 depends on (X86 || SH_MPC1211) 124 ---help--- 125 There are two drivers for MFM/RLL/IDE disks. Most people use just 126 the new enhanced driver by itself. This option however installs the 127 old hard disk driver to control the primary IDE/disk interface in 128 the system, leaving the new enhanced IDE driver to take care of only 129 the 2nd/3rd/4th IDE interfaces. Doing this will prevent you from 130 having an IDE/ATAPI CD-ROM or tape drive connected to the primary 131 IDE interface. Choosing this option may be useful for older systems 132 which have MFM/RLL/ESDI controller+drives at the primary port 133 address (0x1f0), along with IDE drives at the secondary/3rd/4th port 134 addresses. 135 136 Normally, just say N here; you will then use the new driver for all 137 4 interfaces. 138 139config BLK_DEV_IDEDISK 140 tristate "Include IDE/ATA-2 DISK support" 141 ---help--- 142 This will include enhanced support for MFM/RLL/IDE hard disks. If 143 you have a MFM/RLL/IDE disk, and there is no special reason to use 144 the old hard disk driver instead, say Y. If you have an SCSI-only 145 system, you can say N here. 146 147 To compile this driver as a module, choose M here: the 148 module will be called ide-disk. 149 Do not compile this driver as a module if your root file system 150 (the one containing the directory /) is located on the IDE disk. 151 152 If unsure, say Y. 153 154config IDEDISK_MULTI_MODE 155 bool "Use multiple sector mode for Programmed Input/Output by default" 156 help 157 This setting is irrelevant for most IDE disks, with direct memory 158 access, to which multiple sector mode does not apply. Multiple sector 159 mode is a feature of most modern IDE hard drives, permitting the 160 transfer of multiple sectors per Programmed Input/Output interrupt, 161 rather than the usual one sector per interrupt. When this feature is 162 enabled, it can reduce operating system overhead for disk Programmed 163 Input/Output. On some systems, it also can increase the data 164 throughput of Programmed Input/Output. Some drives, however, seemed 165 to run slower with multiple sector mode enabled. Some drives claimed 166 to support multiple sector mode, but lost data at some settings. 167 Under rare circumstances, such failures could result in massive 168 filesystem corruption. 169 170 If you get the following error, try to say Y here: 171 172 hda: set_multmode: status=0x51 { DriveReady SeekComplete Error } 173 hda: set_multmode: error=0x04 { DriveStatusError } 174 175 If in doubt, say N. 176 177config BLK_DEV_IDECS 178 tristate "PCMCIA IDE support" 179 depends on PCMCIA 180 help 181 Support for Compact Flash cards, outboard IDE disks, tape drives, 182 and CD-ROM drives connected through a PCMCIA card. 183 184config BLK_DEV_DELKIN 185 tristate "Cardbus IDE support (Delkin/ASKA/Workbit)" 186 depends on CARDBUS && PCI 187 help 188 Support for Delkin, ASKA, and Workbit Cardbus CompactFlash 189 Adapters.

ATAPI is 195 a newer protocol used by IDE CD-ROM and TAPE drives, similar to the 196 SCSI protocol. Most new CD-ROM drives use ATAPI, including the 197 NEC-260, Mitsumi FX400, Sony 55E, and just about all non-SCSI 198 double(2X) or better speed drives. 199 200 If you say Y here, the CD-ROM drive will be identified at boot time 201 along with other IDE devices, as "hdb" or "hdc", or something 202 similar (check the boot messages with dmesg). If this is your only 203 CD-ROM drive, you can say N to all other CD-ROM options, but be sure 204 to say Y or M to "ISO 9660 CD-ROM file system support". 205 206 To compile this driver as a module, choose M here: the 207 module will be called ide-cd. 208 209config BLK_DEV_IDECD_VERBOSE_ERRORS 210 bool "Verbose error logging for IDE/ATAPI CDROM driver" if EMBEDDED 211 depends on BLK_DEV_IDECD 212 default y 213 help 214 Turn this on to have the driver print out the meanings of the 215 ATAPI error codes.

If you have an SCSI tape drive 224 however, you can say N here. 225 226 You should also say Y if you have an OnStream DI-30 tape drive; this 227 will not work with the SCSI protocol, until there is support for the 228 SC-30 and SC-50 versions. 229 230 If you say Y here, the tape drive will be identified at boot time 231 along with other IDE devices, as "hdb" or "hdc", or something 232 similar, and will be mapped to a character device such as "ht0" 233 (check the boot messages with dmesg). Be sure to consult the 234 <file:drivers/ide/ide-tape.c> and <file:Documentation/ide.txt> files 235 for usage information. 236 237 To compile this driver as a module, choose M here: the 238 module will be called ide-tape. 239 240config BLK_DEV_IDEFLOPPY 241 tristate "Include IDE/ATAPI FLOPPY support" 242 ---help--- 243 If you have an IDE floppy drive which uses the ATAPI protocol, 244 answer Y. ATAPI is a newer protocol used by IDE CD-ROM/tape/floppy 245 drives, similar to the SCSI protocol. 246 247 The LS-120 and the IDE/ATAPI Iomega ZIP drive are also supported by 248 this driver. For information about jumper settings and the question 249 of when a ZIP drive uses a partition table, see 250 <http://www.win.tue.nl/~aeb/linux/zip/zip-1.html>. 251 (ATAPI PD-CD/CDR drives are not supported by this driver; support 252 for PD-CD/CDR drives is available if you answer Y to 253 "SCSI emulation support", below). 254 255 If you say Y here, the FLOPPY drive will be identified along with 256 other IDE devices, as "hdb" or "hdc", or something similar (check 257 the boot messages with dmesg). 258 259 To compile this driver as a module, choose M here: the 260 module will be called ide-floppy. 261 262config BLK_DEV_IDESCSI 263 tristate "SCSI emulation support" 264 depends on SCSI 265 ---help--- 266 WARNING: ide-scsi is no longer needed for cd writing applications! 267 The 2.6 kernel supports direct writing to ide-cd, which eliminates 268 the need for ide-scsi + the entire scsi stack just for writing a 269 cd. The new method is more efficient in every way. 270 271 This will provide SCSI host adapter emulation for IDE ATAPI devices, 272 and will allow you to use a SCSI device driver instead of a native 273 ATAPI driver. 274 275 This is useful if you have an ATAPI device for which no native 276 driver has been written (for example, an ATAPI PD-CD drive); 277 you can then use this emulation together with an appropriate SCSI 278 device driver. In order to do this, say Y here and to "SCSI support" 279 and "SCSI generic support", below. You must then provide the kernel 280 command line "hdx=ide-scsi" (try "man bootparam" or see the 281 documentation of your boot loader (lilo or loadlin) about how to 282 pass options to the kernel at boot time) for devices if you want the 283 native EIDE sub-drivers to skip over the native support, so that 284 this SCSI emulation can be used instead. 285 286 Note that this option does NOT allow you to attach SCSI devices to a 287 box that doesn't have a SCSI host adapter installed. 288 289 If both this SCSI emulation and native ATAPI support are compiled 290 into the kernel, the native support will be used. 291 292config BLK_DEV_IDEACPI 293 bool "IDE ACPI support" 294 depends on ACPI 295 ---help--- 296 Implement ACPI support for generic IDE devices.

One solution 606 for this problem are special LILO commands for redirecting the 607 reference to device 0x80. The other solution is to say Y to "Boot 608 off-board chipsets first support" (CONFIG_BLK_DEV_OFFBOARD) unless 609 your mother board has the chipset natively mounted.
