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/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/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/ide.txt for help/info on IDE drives" 100 101config IDE_TIMINGS 102 bool 103 104config IDE_ATAPI 105 bool 106 107config BLK_DEV_IDE_SATA 108 bool "Support for SATA (deprecated; conflicts with libata SATA driver)" 109 default n 110 ---help--- 111 There are two drivers for Serial ATA controllers. 112 113 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". 117 118 The IDE driver (which you are currently configuring) supports 119 a few first-generation SATA controllers. 120 121 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 125 PATA controllers. 126 127 If unsure, say N. 128 129config BLK_DEV_IDEDISK 130 tristate "Include IDE/ATA-2 DISK support" 131 ---help--- 132 This will include enhanced support for MFM/RLL/IDE hard disks.

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. 159 160 If you get the following error, try to say Y here: 161 162 hda: set_multmode: status=0x51 { DriveReady SeekComplete Error } 163 hda: set_multmode: error=0x04 { DriveStatusError } 164 165 If in doubt, say N. 166 167config BLK_DEV_IDECS 168 tristate "PCMCIA IDE support" 169 depends on PCMCIA 170 help 171 Support for Compact Flash cards, outboard IDE disks, tape drives, 172 and CD-ROM drives connected through a PCMCIA card. 173 174config BLK_DEV_DELKIN 175 tristate "Cardbus IDE support (Delkin/ASKA/Workbit)" 176 depends on CARDBUS && PCI 177 help 178 Support for Delkin, ASKA, and Workbit Cardbus CompactFlash 179 Adapters.

If you have an SCSI tape drive 215 however, you can say N here. 216 217 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. 220 221 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).

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). 246 247 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). 250 251 To compile this driver as a module, choose M here: the 252 module will be called ide-floppy. 253 254config BLK_DEV_IDESCSI 255 tristate "SCSI emulation support" 256 depends on SCSI 257 select IDE_ATAPI 258 ---help--- 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. 263 264 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 266 ATAPI driver. 267 268 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. 278 279 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. 281 282 If both this SCSI emulation and native ATAPI support are compiled 283 into the kernel, the native support will be used. 284 285config BLK_DEV_IDEACPI 286 bool "IDE ACPI support" 287 depends on ACPI 288 ---help--- 289 Implement ACPI support for generic IDE devices.
