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

109 The main driver, "libata", uses the SCSI subsystem
110 and supports most modern SATA controllers. In order to use it
111 you may take a look at "Serial ATA (prod) and Parallel ATA
112 (experimental) drivers".
1da177e4

114 The IDE driver (which you are currently configuring) supports
115 a few first-generation SATA controllers.

117 In order to eliminate conflicts between the two subsystems,
118 this config option enables the IDE driver's SATA support.
119 Normally this is disabled, as it is preferred that libata
120 supports SATA controllers, and this (IDE) driver supports

143 This setting is irrelevant for most IDE disks, with direct memory
144 access, to which multiple sector mode does not apply. Multiple sector
145 mode is a feature of most modern IDE hard drives, permitting the
146 transfer of multiple sectors per Programmed Input/Output interrupt,
147 rather than the usual one sector per interrupt. When this feature is
148 enabled, it can reduce operating system overhead for disk Programmed
149 Input/Output. On some systems, it also can increase the data
150 throughput of Programmed Input/Output. Some drives, however, seemed
151 to run slower with multiple sector mode enabled. Some drives claimed
152 to support multiple sector mode, but lost data at some settings.
153 Under rare circumstances, such failures could result in massive
154 filesystem corruption.

256
257 This will provide SCSI host adapter emulation for IDE ATAPI devices,
258 and will allow you to use a SCSI device driver instead of a native
259 ATAPI driver.
260
261 This is useful if you have an ATAPI device for which no native
262 driver has been written (for example, an ATAPI PD-CD drive);
263 you can then use this emulation together with an appropriate SCSI
264 device driver. In order to do this, say Y here and to "SCSI support"
265 and "SCSI generic support", below. You must then provide the kernel
266 command line "hdx=ide-scsi" (try "man bootparam" or see the
267 documentation of your boot loader (lilo or loadlin) about how to
268 pass options to the kernel at boot time) for devices if you want the
269 native EIDE sub-drivers to skip over the native support, so that
270 this SCSI emulation can be used instead.

1102 help
1103 There are two drivers for MFM/RLL/IDE hard disks. Most people use
1104 the newer enhanced driver, but this old one is still around for two
1105 reasons. Some older systems have strange timing problems and seem to
1106 work only with the old driver (which itself does not work with some
1107 newer systems). The other reason is that the old driver is smaller,
1108 since it lacks the enhanced functionality of the new one. This makes
1109 it a good choice for systems with very tight memory restrictions, or
1110 for systems with only older MFM/RLL/ESDI drives. Choosing the old
1111 driver can save 13 KB or so of kernel memory.
1112

BZ
1113 If you want to use this driver together with the new one you have
1114 to use "hda=noprobe hdb=noprobe" kernel parameters to prevent the new
1115 driver from probing the primary interface.
1116
1da177e4
LT
1117 If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1118 instead of this one. For more detailed information, read the
1119 Disk-HOWTO, available from
