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

| There are two drivers for Serial ATA controllers. |

| This setting is irrelevant for most IDE disks, with direct memory |

| mode is a feature of most modern IDE hard drives, permitting the |
| transfer of multiple sectors per Programmed Input/Output interrupt, |
| rather than the usual one sector per interrupt. When this feature is |
| enabled, it can reduce operating system overhead for disk Programmed |
| Input/Output. On some systems, it also can increase the data |
| throughput of Programmed Input/Output. Some drives, however, seemed |
| to run slower with multiple sector mode enabled. Some drives claimed |
| to support multiple sector mode, but lost data at some settings. |

| you can then use this emulation together with an appropriate SCSI |

| for systems with only older MFM/RLL/ESDI drives. Choosing the old |
