16 If you say Y here, your kernel will be able to manage low cost mass
17 storage units such as ATA/(E)IDE and ATAPI units. The most common
18 cases are IDE hard drives and ATAPI CD-ROM drives.
19
20 If your system is pure SCSI and doesn't use these interfaces, you
21 can say N here.
22
23 Integrated Disk Electronics (IDE aka ATA-1) is a connecting standard
24 for mass storage units such as hard disks. It was designed by
25 Western Digital and Compaq Computer in 1984. It was then named
26 ST506. Quite a number of disks use the IDE interface.
27
28 AT Attachment (ATA) is the superset of the IDE specifications.
29 ST506 was also called ATA-1.
30
31 Fast-IDE is ATA-2 (also named Fast ATA), Enhanced IDE (EIDE) is
32 ATA-3. It provides support for larger disks (up to 8.4GB by means of
33 the LBA standard), more disks (4 instead of 2) and for other mass
34 storage units such as tapes and cdrom. UDMA/33 (aka UltraDMA/33) is
35 ATA-4 and provides faster (and more CPU friendly) transfer modes
36 than previous PIO (Programmed processor Input/Output) from previous
37 ATA/IDE standards by means of fast DMA controllers.
38
39 ATA Packet Interface (ATAPI) is a protocol used by EIDE tape and
40 CD-ROM drives, similar in many respects to the SCSI protocol.
41
42 SMART IDE (Self Monitoring, Analysis and Reporting Technology) was
43 designed in order to prevent data corruption and disk crash by
44 detecting pre hardware failure conditions (heat, access time, and
45 the like...). Disks built since June 1995 may follow this standard.
46 The kernel itself doesn't manage this; however there are quite a
47 number of user programs such as smart that can query the status of
48 SMART parameters from disk drives.

106 ---help---
107 There are two drivers for Serial ATA controllers.
108
109 The main driver, "libata", uses the SCSI subsystem
110 and supports most modern SATA controllers. In order to use it
111 you may take a look at "Serial ATA (prod) and Parallel ATA
112 (experimental) drivers".
113
114 The IDE driver (which you are currently configuring) supports
115 a few first-generation SATA controllers.
116
117 In order to eliminate conflicts between the two subsystems,
118 this config option enables the IDE driver's SATA support.

135 IDE interface. Choosing this option may be useful for older systems
136 which have MFM/RLL/ESDI controller+drives at the primary port

161 This setting is irrelevant for most IDE disks, with direct memory

163 mode is a feature of most modern IDE hard drives, permitting the
164 transfer of multiple sectors per Programmed Input/Output interrupt,
165 rather than the usual one sector per interrupt. When this feature is
166 enabled, it can reduce operating system overhead for disk Programmed
167 Input/Output. On some systems, it also can increase the data
168 throughput of Programmed Input/Output. Some drives, however, seemed
169 to run slower with multiple sector mode enabled. Some drives claimed
170 to support multiple sector mode, but lost data at some settings.
171 Under rare circumstances, such failures could result in massive

1123 bool "Old hard disk (MFM/RLL/IDE) driver"
1124 depends on BLK_DEV_IDE=n
1125 help
1126 There are two drivers for MFM/RLL/IDE hard disks. Most people use
1127 the newer enhanced driver, but this old one is still around for two
1128 reasons. Some older systems have strange timing problems and seem to
1129 work only with the old driver (which itself does not work with some
1130 newer systems). The other reason is that the old driver is smaller,
1131 since it lacks the enhanced functionality of the new one. This makes
1132 it a good choice for systems with very tight memory restrictions, or
1133 for systems with only older MFM/RLL/ESDI drives. Choosing the old
1134 driver can save 13 KB or so of kernel memory.
1135
1136 If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1137 instead of this one. For more detailed information, read the
1138 Disk-HOWTO, available from
1139 <http://www.tldp.org/docs.html#howto>.
