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.
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.

46 To compile this driver as a module, choose M here: the
47 module will be called ide.

70 disk/cdrom/tape/floppy drives.
71
72 Useful information about large (>540 MB) IDE disks, multiple
73 interfaces, what to do if ATA/IDE devices are not automatically
74 detected, sound card ATA/IDE ports, module support, and other
75 topics, is contained in <file:Documentation/ide.txt>. For detailed
76 information about hard drives, consult the Disk-HOWTO and the
77 Multi-Disk-HOWTO, available from
78 <http://www.tldp.org/docs.html#howto>.

102 There are two drivers for Serial ATA controllers.
103
104 The main driver, "libata", exists inside the SCSI subsystem
105 and supports most modern SATA controllers.
106
107 The IDE driver (which you are currently configuring) supports
108 a few first-generation SATA controllers.
109
110 In order to eliminate conflicts between the two subsystems,
111 this config option enables the IDE driver's SATA support.

123 the new enhanced driver by itself. This option however installs the
124 old hard disk driver to control the primary IDE/disk interface in
125 the system, leaving the new enhanced IDE driver to take care of only
126 the 2nd/3rd/4th IDE interfaces. Doing this will prevent you from
127 having an IDE/ATAPI CD-ROM or tape drive connected to the primary
128 IDE interface. Choosing this option may be useful for older systems
129 which have MFM/RLL/ESDI controller+drives at the primary port
130 address (0x1f0), along with IDE drives at the secondary/3rd/4th port
131 addresses.

243
244 This will provide SCSI host adapter emulation for IDE ATAPI devices,
245 and will allow you to use a SCSI device driver instead of a native
246 ATAPI driver.
247
248 This is useful if you have an ATAPI device for which no native
249 driver has been written (for example, an ATAPI PD-CD drive);
250 you can then use this emulation together with an appropriate SCSI
251 device driver. In order to do this, say Y here and to "SCSI support"
252 and "SCSI generic support", below. You must then provide the kernel
253 command line "hdx=ide-scsi" (try "man bootparam" or see the
254 documentation of your boot loader (lilo or loadlin) about how to
255 pass options to the kernel at boot time) for devices if you want the
256 native EIDE sub-drivers to skip over the native support, so that
257 this SCSI emulation can be used instead.
258
259 Note that this option does NOT allow you to attach SCSI devices to a
260 box that doesn't have a SCSI host adapter installed.

1015 This driver is enabled at runtime using the "ide0=dtc2278" kernel
1016 boot parameter. It enables support for the secondary IDE interface
1017 of the DTC-2278 card, and permits faster I/O speeds to be set as
1018 well. See the <file:Documentation/ide.txt> and

1056 There are unclear terms in ATA-4 and ATA-5 standards how certain
1057 hardware (an 80c ribbon) should be detected. Different interpretations
1058 of the standards have been released in hardware. This causes problems:
1059 for example, a host with Ultra Mode 4 (or higher) will not run
1060 in that mode with an 80c ribbon.

1062 If you are experiencing compatibility or performance problems, you
1063 MAY try to answering Y here. However, it does not necessarily solve
1064 any of your problems, it could even cause more of them.
1065
1066 It is normally safe to answer Y; however, the default is N.

1075 depends on BLK_DEV_IDE=n
1076 help
1077 There are two drivers for MFM/RLL/IDE hard disks. Most people use
1078 the newer enhanced driver, but this old one is still around for two
1079 reasons. Some older systems have strange timing problems and seem to
1080 work only with the old driver (which itself does not work with some
1081 newer systems). The other reason is that the old driver is smaller,
1082 since it lacks the enhanced functionality of the new one. This makes
1083 it a good choice for systems with very tight memory restrictions, or
1084 for systems with only older MFM/RLL/ESDI drives. Choosing the old
1085 driver can save 13 KB or so of kernel memory.
1086
1087 If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1088 instead of this one. For more detailed information, read the
1089 Disk-HOWTO, available from
1090 <http://www.tldp.org/docs.html#howto>.
