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

113 The main driver, "libata", uses the SCSI subsystem

115 you may take a look at "Serial ATA (prod) and Parallel ATA
116 (experimental) drivers".

122 this config option enables the IDE driver's SATA support.

147 This setting is irrelevant for most IDE disks, with direct memory
148 access, to which multiple sector mode does not apply. Multiple sector
149 mode is a feature of most modern IDE hard drives, permitting the
150 transfer of multiple sectors per Programmed Input/Output interrupt,
151 rather than the usual one sector per interrupt. When this feature is
152 enabled, it can reduce operating system overhead for disk Programmed
153 Input/Output. On some systems, it also can increase the data
154 throughput of Programmed Input/Output. Some drives, however, seemed
155 to run slower with multiple sector mode enabled. Some drives claimed
156 to support multiple sector mode, but lost data at some settings.
157 Under rare circumstances, such failures could result in massive

1043 help
1044 There are two drivers for MFM/RLL/IDE hard disks. Most people use
1045 the newer enhanced driver, but this old one is still around for two
1046 reasons. Some older systems have strange timing problems and seem to
1047 work only with the old driver (which itself does not work with some
1048 newer systems). The other reason is that the old driver is smaller,
1049 since it lacks the enhanced functionality of the new one. This makes
1050 it a good choice for systems with very tight memory restrictions, or
1051 for systems with only older MFM/RLL/ESDI drives. Choosing the old
1052 driver can save 13 KB or so of kernel memory.
1053
80aa31cb
BZ
1054 If you want to use this driver together with the new one you have
1055 to use "hda=noprobe hdb=noprobe" kernel parameters to prevent the new
1056 driver from probing the primary interface.
1057
1da177e4

1058 If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1059 instead of this one. For more detailed information, read the
