《嵌入式系统设计与实例开发实验教材二源码》Linux内核移植与编译实验

  People with SCSI-only systems can say N here.

Generic 4 drives/port support
CONFIG_BLK_DEV_4DRIVES
  Certain older chipsets, including the Tekram 690CD, use a single set
  of I/O ports at 0x1f0 to control up to four drives, instead of the
  customary two drives per port. Support for this can be enabled at
  runtime using the "ide0=four" kernel boot parameter if you say Y
  here.

ALI M14xx support
CONFIG_BLK_DEV_ALI14XX
  This driver is enabled at runtime using the "ide0=ali14xx" kernel
  boot parameter.  It enables support for the secondary IDE interface
  of the ALI M1439/1443/1445/1487/1489 chipsets, and permits faster
  I/O speeds to be set as well.  See the files
  <file:Documentation/ide.txt> and <file:drivers/ide/ali14xx.c> for
  more info.

DTC-2278 support
CONFIG_BLK_DEV_DTC2278
  This driver is enabled at runtime using the "ide0=dtc2278" kernel
  boot parameter. It enables support for the secondary IDE interface
  of the DTC-2278 card, and permits faster I/O speeds to be set as
  well. See the <file:Documentation/ide.txt> and
  <file:drivers/ide/dtc2278.c> files for more info.

Holtek HT6560B support
CONFIG_BLK_DEV_HT6560B
  This driver is enabled at runtime using the "ide0=ht6560b" kernel
  boot parameter. It enables support for the secondary IDE interface
  of the Holtek card, and permits faster I/O speeds to be set as well.
  See the <file:Documentation/ide.txt> and
  <file:drivers/ide/ht6560b.c> files for more info.

PROMISE DC4030 support (EXPERIMENTAL)
CONFIG_BLK_DEV_PDC4030
  This driver provides support for the secondary IDE interface and
  cache of Promise IDE chipsets, e.g. DC4030 and DC5030.  This driver
  is known to incur timeouts/retries during heavy I/O to drives
  attached to the secondary interface.  CD-ROM and TAPE devices are
  not supported yet.  This driver is enabled at runtime using the
  "ide0=dc4030" kernel boot parameter.  See the
  <file:Documentation/ide.txt> and <file:drivers/ide/pdc4030.c> files
  for more info.

QDI QD65XX support
CONFIG_BLK_DEV_QD65XX
  This driver is enabled at runtime using the "ide0=qd65xx" kernel
  boot parameter.  It permits faster I/O speeds to be set.  See the
  <file:Documentation/ide.txt> and <file:drivers/ide/qd65xx.c> for
  more info.

UMC 8672 support
CONFIG_BLK_DEV_UMC8672
  This driver is enabled at runtime using the "ide0=umc8672" kernel
  boot parameter. It enables support for the secondary IDE interface
  of the UMC-8672, and permits faster I/O speeds to be set as well.
  See the files <file:Documentation/ide.txt> and
  <file:drivers/ide/umc8672.c> for more info.

Amiga Gayle IDE interface support
CONFIG_BLK_DEV_GAYLE
  This is the IDE driver for the builtin IDE interface on some Amiga
  models. It supports both the `A1200 style' (used in A600 and A1200)
  and `A4000 style' (used in A4000 and A4000T) of the Gayle IDE
  interface. Say Y if you have such an Amiga model and want to use IDE
  devices (hard disks, CD-ROM drives, etc.) that are connected to the
  builtin IDE interface.

Falcon IDE interface support
CONFIG_BLK_DEV_FALCON_IDE
  This is the IDE driver for the builtin IDE interface on the Atari
  Falcon. Say Y if you have a Falcon and want to use IDE devices (hard
  disks, CD-ROM drives, etc.) that are connected to the builtin IDE
  interface.

Amiga Buddha/Catweasel/X-Surf IDE interface support (EXPERIMENTAL)
CONFIG_BLK_DEV_BUDDHA
  This is the IDE driver for the IDE interfaces on the Buddha, 
  Catweasel and X-Surf expansion boards.  It supports up to two interfaces 
  on the Buddha, three on the Catweasel and two on the X-Surf.

  Say Y if you have a Buddha or Catweasel expansion board and want to
  use IDE devices (hard disks, CD-ROM drives, etc.) that are connected
  to one of its IDE interfaces.

Amiga IDE Doubler support (EXPERIMENTAL)
CONFIG_BLK_DEV_IDEDOUBLER
  This driver provides support for the so-called `IDE doublers' (made
  by various manufacturers, e.g. Eyetech) that can be connected to the
  builtin IDE interface of some Amiga models. Using such an IDE
  doubler, you can connect up to four instead of two IDE devices on
  the Amiga's builtin IDE interface.

  Note that the normal Amiga Gayle IDE driver may not work correctly
  if you have an IDE doubler and don't enable this driver!

  Say Y if you have an IDE doubler.  The driver is enabled at kernel
  runtime using the "ide=doubler" kernel boot parameter.

WarpEngine SCSI support
CONFIG_WARPENGINE_SCSI
  Support for MacroSystem Development's WarpEngine Amiga SCSI-2
  controller. Info at
  <http://www.lysator.liu.se/amiga/ar/guide/ar310.guide?FEATURE5>.

Builtin PowerMac IDE support
CONFIG_BLK_DEV_IDE_PMAC
  This driver provides support for the built-in IDE controller on
  most of the recent Apple Power Macintoshes and PowerBooks.
  If unsure, say Y.

PowerMac IDE DMA support
CONFIG_BLK_DEV_IDEDMA_PMAC
  This option allows the driver for the built-in IDE controller on
  Power Macintoshes and PowerBooks to use DMA (direct memory access)
  to transfer data to and from memory.  Saying Y is safe and improves
  performance.

Use DMA by default
CONFIG_BLK_DEV_IDEDMA_PMAC_AUTO
  This option allows the driver for the built-in IDE controller on
  Power Macintoshes and PowerBooks to use DMA automatically, without
  it having to be explicitly enabled.  This option is provided because
  of concerns about a couple of cases where using DMA on buggy PC
  hardware may have caused damage.  Saying Y should be safe on all
  Apple machines.

Macintosh Quadra/Powerbook IDE interface support
CONFIG_BLK_DEV_MAC_IDE
  This is the IDE driver for the builtin IDE interface on some m68k
  Macintosh models. It supports both the `Quadra style' (used in
  Quadra/ Centris 630 and Performa 588 models) and `Powerbook style'
  (used in the Powerbook 150 and 190 models) IDE interface.

  Say Y if you have such an Macintosh model and want to use IDE
  devices (hard disks, CD-ROM drives, etc.) that are connected to the
  builtin IDE interface.

ICS IDE interface support
CONFIG_BLK_DEV_IDE_ICSIDE
  On Acorn systems, say Y here if you wish to use the ICS IDE
  interface card.  This is not required for ICS partition support.
  If you are unsure, say N to this.

ICS DMA support
CONFIG_BLK_DEV_IDEDMA_ICS
  Say Y here if you want to add DMA (Direct Memory Access) support to
  the ICS IDE driver.

Use ICS DMA by default
CONFIG_IDEDMA_ICS_AUTO
  Prior to kernel version 2.1.112, Linux used to automatically use
  DMA for IDE drives and chipsets which support it. Due to concerns
  about a couple of cases where buggy hardware may have caused damage,
  the default is now to NOT use DMA automatically. To revert to the
  previous behaviour, say Y to this question.

  If you suspect your hardware is at all flakey, say N here.
  Do NOT email the IDE kernel people regarding this issue!

XT hard disk support
CONFIG_BLK_DEV_XD
  Very old 8 bit hard disk controllers used in the IBM XT computer
  will be supported if you say Y here.

  If you want to compile the driver as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want),
  say M here and read <file:Documentation/modules.txt>. The module
  will be called xd.o.

  It's pretty unlikely that you have one of these: say N.

PS/2 ESDI hard disk support
CONFIG_BLK_DEV_PS2
  Say Y here if you have a PS/2 machine with a MCA bus and an ESDI
  hard disk.

  If you want to compile the driver as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want),
  say M here and read <file:Documentation/modules.txt>.  The module
  will be called ps2esdi.o.

Mylex DAC960/DAC1100 PCI RAID Controller support
CONFIG_BLK_DEV_DAC960
  This driver adds support for the Mylex DAC960, AcceleRAID, and
  eXtremeRAID PCI RAID controllers.  See the file
  <file:Documentation/README.DAC960> for further information about
  this driver.

  If you want to compile the driver as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want),
  say M here and read <file:Documentation/modules.txt>.  The module
  will be called DAC960.o.

Parallel port IDE device support
CONFIG_PARIDE
  There are many external CD-ROM and disk devices that connect through
  your computer's parallel port. Most of them are actually IDE devices
  using a parallel port IDE adapter. This option enables the PARIDE
  subsystem which contains drivers for many of these external drives.
  Read <file:Documentation/paride.txt> for more information.

  If you have said Y to the "Parallel-port support" configuration
  option, you may share a single port between your printer and other
  parallel port devices. Answer Y to build PARIDE support into your
  kernel, or M if you would like to build it as a loadable module. If
  your parallel port support is in a loadable module, you must build
  PARIDE as a module. If you built PARIDE support into your kernel,
  you may still build the individual protocol modules and high-level
  drivers as loadable modules. If you build this support as a module,
  it will be called paride.o.

  To use the PARIDE support, you must say Y or M here and also to at
  least one high-level driver (e.g. "Parallel port IDE disks",
  "Parallel port ATAPI CD-ROMs", "Parallel port ATAPI disks" etc.) and
  to at least one protocol driver (e.g. "ATEN EH-100 protocol",
  "MicroSolutions backpack protocol", "DataStor Commuter protocol"
  etc.).

Parallel port IDE disks
CONFIG_PARIDE_PD
  This option enables the high-level driver for IDE-type disk devices
  connected through a parallel port. If you chose to build PARIDE
  support into your kernel, you may answer Y here to build in the
  parallel port IDE driver, otherwise you should answer M to build
  it as a loadable module. The module will be called pd.o. You
  must also have at least one parallel port protocol driver in your
  system. Among the devices supported by this driver are the SyQuest
  EZ-135, EZ-230 and SparQ drives, the Avatar Shark and the backpack
  hard drives from MicroSolutions.

Parallel port ATAPI CD-ROMs
CONFIG_PARIDE_PCD
  This option enables the high-level driver for ATAPI CD-ROM devices
  connected through a parallel port. If you chose to build PARIDE
  support into your kernel, you may answer Y here to build in the
  parallel port ATAPI CD-ROM driver, otherwise you should answer M to
  build it as a loadable module. The module will be called pcd.o. You
  must also have at least one parallel port protocol driver in your
  system. Among the devices supported by this driver are the
  MicroSolutions backpack CD-ROM drives and the Freecom Power CD. If
  you have such a CD-ROM drive, you should also say Y or M to "ISO
  9660 CD-ROM file system support" below, because that's the file
  system used on CD-ROMs.

Parallel port ATAPI disks
CONFIG_PARIDE_PF
  This option enables the high-level driver for ATAPI disk devices
  connected through a parallel port. If you chose to build PARIDE
  support into your kernel, you may answer Y here to build in the
  parallel port ATAPI disk driver, otherwise you should answer M
  to build it as a loadable module. The module will be called pf.o.
  You must also have at least one parallel port protocol driver in
  your system. Among the devices supported by this driver are the
  MicroSolutions backpack PD/CD drive and the Imation Superdisk
  LS-120 drive.

Parallel port ATAPI tapes
CONFIG_PARIDE_PT
  This option enables the high-level driver for ATAPI tape devices
  connected through a parallel port. If you chose to build PARIDE
  support into your kernel, you may answer Y here to build in the
  parallel port ATAPI disk driver, otherwise you should answer M
  to build it as a loadable module. The module will be called pt.o.
  You must also have at least one parallel port protocol driver in
  your system. Among the devices supported by this driver is the
  parallel port version of the HP 5GB drive.

Parallel port generic ATAPI devices
CONFIG_PARIDE_PG
  This option enables a special high-level driver for generic ATAPI
  devices connected through a parallel port. The driver allows user
  programs, such as cdrtools, to send ATAPI commands directly to a
  device.

  If you chose to build PARIDE support into your kernel, you may
  answer Y here to build in the parallel port generic ATAPI driver,
  otherwise you should answer M to build it as a loadable module. The
  module will be called pg.o.

  You must also have at least one parallel port protocol driver in
  your system.

  This driver implements an API loosely related to the generic SCSI
  driver. See <file:include/linux/pg.h>. for details.

  You can obtain the most recent version of cdrtools from
  <ftp://ftp.fokus.gmd.de/pub/unix/cdrecord/>. Versions 1.6.1a3 and
  later fully support this driver.

ATEN EH-100 protocol
CONFIG_PARIDE_ATEN
  This option enables support for the ATEN EH-100 parallel port IDE
  protocol. This protocol is used in some inexpensive low performance
  parallel port kits made in Hong Kong. If you chose to build PARIDE
  support into your kernel, you may answer Y here to build in the
  protocol driver, otherwise you should answer M to build it as a
  loadable module. The module will be called aten.o. You must also
  have a high-level driver for the type of device that yo
