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.
|

The main driver, "libata", exists inside the SCSI subsystem
|

and supports most modern SATA controllers.
|

The IDE driver (which you are currently configuring) supports

In order to eliminate conflicts between the two subsystems,

this config option enables the IDE driver's SATA support.

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

If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver

instead of this one. For more detailed information, read the
