11 ---help---
12 If you say Y here, your kernel will be able to manage low cost mass
13 storage units such as ATA/(E)IDE and ATAPI units. The most common
14 cases are IDE hard drives and ATAPI CD-ROM drives.
16 If your system is pure SCSI and doesn't use these interfaces, you
17 can say N here.
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.
24 AT Attachment (ATA) is the superset of the IDE specifications.
25 ST506 was also called ATA-1.
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.
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.
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.
46 To compile this driver as a module, choose M here: the
47 module will be called ide.

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.
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>.
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/>.
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.
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.

103 There are two drivers for Serial ATA controllers.

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".
110 The IDE driver (which you are currently configuring) supports
111 a few first-generation SATA controllers.
113 In order to eliminate conflicts between the two subsystems,
114 this config option enables the IDE driver's SATA support.

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

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.
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.
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.
269 Note that this option does NOT allow you to attach SCSI devices to a

1081 There are two drivers for MFM/RLL/IDE hard disks. Most people use

1083 reasons. Some older systems have strange timing problems and seem to
1084 work only with the old driver (which itself does not work with some
1085 newer systems). The other reason is that the old driver is smaller,
1086 since it lacks the enhanced functionality of the new one. This makes

1088 for systems with only older MFM/RLL/ESDI drives. Choosing the old
