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).

The new method is more efficient in every way. 262 263 This will provide SCSI host adapter emulation for IDE ATAPI devices, 264 and will allow you to use a SCSI device driver instead of a native 265 ATAPI driver. 266 267 This is useful if you have an ATAPI device for which no native 268 driver has been written (for example, an ATAPI PD-CD drive); 269 you can then use this emulation together with an appropriate SCSI 270 device driver. In order to do this, say Y here and to "SCSI support" 271 and "SCSI generic support", below. You must then provide the kernel 272 command line "hdx=ide-scsi" (try "man bootparam" or see the 273 documentation of your boot loader (lilo or loadlin) about how to 274 pass options to the kernel at boot time) for devices if you want the 275 native EIDE sub-drivers to skip over the native support, so that 276 this SCSI emulation can be used instead. 277 278 Note that this option does NOT allow you to attach SCSI devices to a 279 box that doesn't have a SCSI host adapter installed. 280 281 If both this SCSI emulation and native ATAPI support are compiled 282 into the kernel, the native support will be used. 283 284config BLK_DEV_IDEACPI 285 bool "IDE ACPI support" 286 depends on ACPI 287 ---help--- 288 Implement ACPI support for generic IDE devices.

Say Y here to include code which tries to automatically 336 detect and correct the problems under Linux. This option also 337 enables access to the secondary IDE ports in some CMD640 based 338 systems. 339 340 This driver will work automatically in PCI based systems (most new 341 systems have PCI slots). But if your system uses VESA local bus 342 (VLB) instead of PCI, you must also supply a kernel boot parameter 343 to enable the CMD640 bugfix/support: "ide0=cmd640_vlb".
