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

1088 help
1089 There are two drivers for MFM/RLL/IDE hard disks. Most people use
1090 the newer enhanced driver, but this old one is still around for two
1091 reasons. Some older systems have strange timing problems and seem to
1092 work only with the old driver (which itself does not work with some
1093 newer systems). The other reason is that the old driver is smaller,
1094 since it lacks the enhanced functionality of the new one. This makes
1095 it a good choice for systems with very tight memory restrictions, or
1096 for systems with only older MFM/RLL/ESDI drives. Choosing the old
1097 driver can save 13 KB or so of kernel memory.
1098
1099 If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1100 instead of this one. For more detailed information, read the
1101 Disk-HOWTO, available from
