| 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. |

| 1080 | There are two drivers for MFM/RLL/IDE hard disks. Most people use |
| 1081 | the newer enhanced driver, but this old one is still around for two |
| 1082 | reasons. Some older systems have strange timing problems and seem to |
| 1083 | work only with the old driver (which itself does not work with some |
| 1084 | newer systems). The other reason is that the old driver is smaller, |
| 1085 | since it lacks the enhanced functionality of the new one. This makes |
| 1086 | it a good choice for systems with very tight memory restrictions, or |
| 1087 | for systems with only older MFM/RLL/ESDI drives. Choosing the old |
| 1088 | driver can save 13 KB or so of kernel memory. |
