13 ---help---
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.

49 module will be called ide.

984 help
985 Certain older chipsets, including the Tekram 690CD, use a single set
986 of I/O ports at 0x1f0 to control up to four drives, instead of the
987 customary two drives per port. Support for this can be enabled at
988 runtime using the "ide0=four" kernel boot parameter if you say Y
989 here.

1045 There are unclear terms in ATA-4 and ATA-5 standards how certain
1046 hardware (an 80c ribbon) should be detected. Different interpretations
1047 of the standards have been released in hardware. This causes problems:
1048 for example, a host with Ultra Mode 4 (or higher) will not run
1049 in that mode with an 80c ribbon.

1064 depends on BLK_DEV_IDE=n
1065 help
1066 There are two drivers for MFM/RLL/IDE hard disks. Most people use
1067 the newer enhanced driver, but this old one is still around for two
1068 reasons. Some older systems have strange timing problems and seem to
1069 work only with the old driver (which itself does not work with some
1070 newer systems). The other reason is that the old driver is smaller,
1071 since it lacks the enhanced functionality of the new one. This makes
1072 it a good choice for systems with very tight memory restrictions, or
1073 for systems with only older MFM/RLL/ESDI drives. Choosing the old
1074 driver can save 13 KB or so of kernel memory.
1075
1076 If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1077 instead of this one. For more detailed information, read the
1078 Disk-HOWTO, available from
1079 <http://www.tldp.org/docs.html#howto>.
