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

b43c5f3d PR |
108 | The main driver, "libata", uses the SCSI subsystem |
109 | and supports most modern SATA controllers. In order to use it | |
110 | you may take a look at "Serial ATA (prod) and Parallel ATA | |
111 | (experimental) drivers". | |
1da177e4 LT |
112 | |
113 | The IDE driver (which you are currently configuring) supports | |
114 | a few first-generation SATA controllers. | |
115 | ||
116 | In order to eliminate conflicts between the two subsystems, | |
117 | this config option enables the IDE driver's SATA support. | |
118 | Normally this is disabled, as it is preferred that libata | |

128 | There are two drivers for MFM/RLL/IDE disks. Most people use just | |

132 | the 2nd/3rd/4th IDE interfaces. Doing this will prevent you from | |
133 | having an IDE/ATAPI CD-ROM or tape drive connected to the primary | |
134 | IDE interface. Choosing this option may be useful for older systems | |

1083 | help | |
1084 | There are two drivers for MFM/RLL/IDE hard disks. Most people use | |
1085 | the newer enhanced driver, but this old one is still around for two | |
1086 | reasons. Some older systems have strange timing problems and seem to | |
1087 | work only with the old driver (which itself does not work with some | |
1088 | newer systems). The other reason is that the old driver is smaller, | |
1089 | since it lacks the enhanced functionality of the new one. This makes | |
1090 | it a good choice for systems with very tight memory restrictions, or | |
1091 | for systems with only older MFM/RLL/ESDI drives. Choosing the old | |
1092 | driver can save 13 KB or so of kernel memory. | |
1093 | ||
1094 | If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver | |
1095 | instead of this one. For more detailed information, read the | |
