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.
45
46	  To compile this driver as a module, choose M here: the
47	  module will be called ide.

49	  For further information, please read <file:Documentation/ide.txt>.

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.

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

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

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.

1116	help
1117	  There are two drivers for MFM/RLL/IDE hard disks. Most people use
1118	  the newer enhanced driver, but this old one is still around for two
1119	  reasons. Some older systems have strange timing problems and seem to
1120	  work only with the old driver (which itself does not work with some
1121	  newer systems). The other reason is that the old driver is smaller,
1122	  since it lacks the enhanced functionality of the new one. This makes
1123	  it a good choice for systems with very tight memory restrictions, or
1124	  for systems with only older MFM/RLL/ESDI drives. Choosing the old
1125	  driver can save 13 KB or so of kernel memory.
1126
1127	  If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1128	  instead of this one. For more detailed information, read the
1129	  Disk-HOWTO, available from
