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.

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.

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.

ATAPI is 182 a newer protocol used by IDE CD-ROM and TAPE drives, similar to the 183 SCSI protocol. Most new CD-ROM drives use ATAPI, including the 184 NEC-260, Mitsumi FX400, Sony 55E, and just about all non-SCSI 185 double(2X) or better speed drives. 186 187 If you say Y here, the CD-ROM drive will be identified at boot time 188 along with other IDE devices, as "hdb" or "hdc", or something 189 similar (check the boot messages with dmesg). If this is your only 190 CD-ROM drive, you can say N to all other CD-ROM options, but be sure 191 to say Y or M to "ISO 9660 CD-ROM file system support". 192 193 Note that older versions of LILO (LInux LOader) cannot properly deal 194 with IDE/ATAPI CD-ROMs, so install LILO 16 or higher, available from 195 <http://lilo.go.dyndns.org/>. 196 197 To compile this driver as a module, choose M here: the 198 module will be called ide-cd. 199 200config BLK_DEV_IDETAPE 201 tristate "Include IDE/ATAPI TAPE support (EXPERIMENTAL)" 202 depends on EXPERIMENTAL 203 help 204 If you have an IDE tape drive using the ATAPI protocol, say Y. 205 ATAPI is a newer protocol used by IDE tape and CD-ROM drives, 206 similar to the SCSI protocol.

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

Say Y here to include code which tries to automatically 320 detect and correct the problems under Linux. This option also 321 enables access to the secondary IDE ports in some CMD640 based 322 systems. 323 324 This driver will work automatically in PCI based systems (most new 325 systems have PCI slots). But if your system uses VESA local bus 326 (VLB) instead of PCI, you must also supply a kernel boot parameter 327 to enable the CMD640 bugfix/support: "ide0=cmd640_vlb". (Try "man 328 bootparam" or see the documentation of your boot loader about how to 329 pass options to the kernel.) 330 331 The CMD640 chip is also used on add-in cards by Acculogic, and on 332 the "CSA-6400E PCI to IDE controller" that some people have.
