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

71 The main driver, "libata", uses the SCSI subsystem
72 and supports most modern SATA controllers. In order to use it
73 you may take a look at "Serial ATA (prod) and Parallel ATA
74 (experimental) drivers".
1da177e4
LT
75
76 The IDE driver (which you are currently configuring) supports
77 a few first-generation SATA controllers.
78
79 In order to eliminate conflicts between the two subsystems,
80 this config option enables the IDE driver's SATA support.
81 Normally this is disabled, as it is preferred that libata
82 supports SATA controllers, and this (IDE) driver supports
83 PATA controllers.

240 This is the generic IDE driver. This driver attaches to the
241 fixed legacy ports (e.g. on PCs 0x1f0/0x170, 0x1e8/0x168 and
242 so on). Please note that if this driver is built into the
243 kernel or loaded before other ATA (IDE or libata) drivers
244 and the controller is located at legacy ports, this driver
245 may grab those ports and thus can prevent the controller
246 specific driver from attaching.
247
248 Also, currently, IDE generic doesn't allow IRQ sharing
249 meaning that the IRQs it grabs won't be available to other
250 controllers sharing those IRQs which usually makes drivers
251 for those controllers fail. Generally, it's not a good idea
