  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.

 107           There are two drivers for Serial ATA controllers.
 108
 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".
 113
 114           The IDE driver (which you are currently configuring) supports
 115           a few first-generation SATA controllers.
 116
 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
 121           PATA controllers.

 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.

 731           This driver ensures (U)DMA support for Victory66 SouthBridges for
 732           SMsC with Intel NorthBridges.  This is an Ultra66 based chipset.
 733           The nice thing about it is that you can mix Ultra/DMA/PIO devices
 734           and it will handle timing cycles.  Since this is an improved
 735           look-a-like to the PIIX4 it should be a nice addition.
 736
 737           If you say Y here, you need to say Y to "Use DMA by default when
 738           available" as well.

1102           newer systems). The other reason is that the old driver is smaller,
1103           since it lacks the enhanced functionality of the new one. This makes
1104           it a good choice for systems with very tight memory restrictions, or
1105           for systems with only older MFM/RLL/ESDI drives. Choosing the old
1106           driver can save 13 KB or so of kernel memory.
1107
1108           If you want to use this driver together with the new one you have
1109           to use "hda=noprobe hdb=noprobe" kernel parameters to prevent the new
1110           driver from probing the primary interface.
1111
1112           If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
1113           instead of this one. For more detailed information, read the
