---help---
If you say Y here, you will use the full-featured IDE driver to
control up to ten ATA/IDE interfaces, each being able to serve a
"master" and a "slave" device, for a total of up to twenty ATA/IDE
disk/cdrom/tape/floppy drives.
Useful information about large (>540 MB) IDE disks, multiple
interfaces, what to do if ATA/IDE devices are not automatically
detected, sound card ATA/IDE ports, module support, and other
topics, is contained in <file:Documentation/ide.txt>. For detailed
information about hard drives, consult the Disk-HOWTO and the
Multi-Disk-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.
To fine-tune ATA/IDE drive/interface parameters for improved
performance, look for the hdparm package at
<ftp://ibiblio.org/pub/Linux/system/hardware/>.
If you want to compile this 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> and
<file:Documentation/ide.txt>. The module will be called ide-mod.
Do not compile this driver as a module if your root file system (the
one containing the directory /) is located on an IDE device.
If you have one or more IDE drives, say Y or M here. If your system
has no IDE drives, or if memory requirements are really tight, you
could say N here, and select the "Old hard disk driver" below
instead to save about 13 KB of memory in the kernel.

---help---
There are two drivers for MFM/RLL/IDE disks. Most people use just
the new enhanced driver by itself. This option however installs the
old hard disk driver to control the primary IDE/disk interface in
the system, leaving the new enhanced IDE driver to take care of only
the 2nd/3rd/4th IDE interfaces. Doing this will prevent you from
having an IDE/ATAPI CD-ROM or tape drive connected to the primary
IDE interface. Choosing this option may be useful for older systems
which have MFM/RLL/ESDI controller+drives at the primary port
address (0x1f0), along with IDE drives at the secondary/3rd/4th port
addresses.
Normally, just say N here; you will then use the new driver for all
4 interfaces.

Should you have a system w/ an AWARD Bios and your drives are larger
than 32GB and it will not boot, one is required to perform a few OEM
operations first. The option is called "STROKE" because it allows
one to "soft clip" the drive to work around a barrier limit. For
Maxtor drives it is called "jumpon.exe". Please search Maxtor's
web-site for "JUMPON.EXE". IBM has a similar tool at:

---help---
If you have a CD-ROM drive using the ATAPI protocol, say Y. ATAPI is
a newer protocol used by IDE CD-ROM and TAPE drives, similar to the
SCSI protocol. Most new CD-ROM drives use ATAPI, including the
NEC-260, Mitsumi FX400, Sony 55E, and just about all non-SCSI
double(2X) or better speed drives.
If you say Y here, the CD-ROM drive will be identified at boot time
along with other IDE devices, as "hdb" or "hdc", or something
similar (check the boot messages with dmesg). If this is your only
CD-ROM drive, you can say N to all other CD-ROM options, but be sure
to say Y or M to "ISO 9660 CD-ROM file system support".
Note that older versions of LILO (LInux LOader) cannot properly deal
with IDE/ATAPI CD-ROMs, so install LILO 16 or higher, available from
<ftp://brun.dyndns.org/pub/linux/lilo/>.
If you want to compile the driver as a module ( = code which can be

If you have an IDE floppy drive which uses the ATAPI protocol,
answer Y. ATAPI is a newer protocol used by IDE CD-ROM/tape/floppy
drives, similar to the SCSI protocol.
The LS-120 and the IDE/ATAPI Iomega ZIP drive are also supported by
this driver. For information about jumper settings and the question
of when a ZIP drive uses a partition table, see
<http://www.win.tue.nl/~aeb/linux/zip/zip-1.html>.
(ATAPI PD-CD/CDR drives are not supported by this driver; support

config BLK_DEV_IDESCSI
tristate "SCSI emulation support"
depends on BLK_DEV_IDE && SCSI
---help---
This will provide SCSI host adapter emulation for IDE ATAPI devices,
and will allow you to use a SCSI device driver instead of a native
ATAPI driver.
This is useful if you have an ATAPI device for which no native
driver has been written (for example, an ATAPI PD-CD or CDR drive);
you can then use this emulation together with an appropriate SCSI
device driver. In order to do this, say Y here and to "SCSI support"
and "SCSI generic support", below. You must then provide the kernel
command line "hdx=ide-scsi" (try "man bootparam" or see the
documentation of your boot loader (lilo or loadlin) about how to
pass options to the kernel at boot time) for devices if you want the
native EIDE sub-drivers to skip over the native support, so that
this SCSI emulation can be used instead. This is required for use of
CD-RW's.
Note that this option does NOT allow you to attach SCSI devices to a
box that doesn't have a SCSI host adapter installed.
If both this SCSI emulation and native ATAPI support are compiled
into the kernel, the native support will be used.

depends on BLK_DEV_IDE && X86
---help---
The CMD-Technologies CMD640 IDE chip is used on many common 486 and
Pentium motherboards, usually in combination with a "Neptune" or
"SiS" chipset. Unfortunately, it has a number of rather nasty
design flaws that can cause severe data corruption under many common
conditions. Say Y here to include code which tries to automatically
detect and correct the problems under Linux. This option also
enables access to the secondary IDE ports in some CMD640 based
systems.
This driver will work automatically in PCI based systems (most new
systems have PCI slots). But if your system uses VESA local bus
(VLB) instead of PCI, you must also supply a kernel boot parameter
to enable the CMD640 bugfix/support: "ide0=cmd640_vlb". (Try "man
bootparam" or see the documentation of your boot loader about how to
pass options to the kernel.)
The CMD640 chip is also used on add-in cards by Acculogic, and on
the "CSA-6400E PCI to IDE controller" that some people have. For
details, read <file:Documentation/ide.txt>.

---help---
If your PCI system uses IDE drive(s) (as opposed to SCSI, say) and
is capable of bus-master DMA operation (most Pentium PCI systems),
you will want to say Y here to reduce CPU overhead. You can then use
the "hdparm" utility to enable DMA for drives for which it was not
enabled automatically. By default, DMA is not enabled automatically
for these drives, but you can change that by saying Y to the
following question "Use DMA by default when available". You can get
the latest version of the hdparm utility from
<ftp://ibiblio.org/pub/Linux/system/hardware/>.
Read the comments at the beginning of <file:drivers/ide/ide-dma.c>

It is safe to say Y to this question.
config BLK_DEV_IDE_TCQ
bool "ATA tagged command queueing (EXPERIMENTAL)"
depends on BLK_DEV_IDEDMA_PCI && EXPERIMENTAL
help
Support for tagged command queueing on ATA disk drives. This enables
the IDE layer to have multiple in-flight requests on hardware that
supports it. For now this includes the IBM Deskstar series drives,
such as the 22GXP, 75GXP, 40GV, 60GXP, and 120GXP (ie any Deskstar made
in the last couple of years), and at least some of the Western
Digital drives in the Expert series (by nature of really being IBM

---help---
Enable tagged command queueing unconditionally on drives that report
support for it. Regardless of the chosen value here, tagging can be
controlled at run time:
echo "using_tcq:32" > /proc/ide/hdX/settings
where any value between 1-32 selects chosen queue depth and enables
TCQ, and 0 disables it. hdparm version 4.7 an above also support
TCQ manipulations.

number, the default value will be used.
config BLK_DEV_OFFBOARD
bool "Boot off-board chipsets first support"
depends on PCI && BLK_DEV_IDEPCI
---help---
Normally, IDE controllers built into the motherboard (on-board
controllers) are assigned to ide0 and ide1 while those on add-in PCI
cards (off-board controllers) are relegated to ide2 and ide3.
Answering Y here will allow you to reverse the situation, with
off-board controllers on ide0/1 and on-board controllers on ide2/3.
This can improve the usability of some boot managers such as lilo
when booting from a drive on an off-board controller.
If you say Y here, and you actually want to reverse the device scan
order as explained above, you also need to issue the kernel command
line option "ide=reverse". (Try "man bootparam" or see the
documentation of your boot loader (lilo or loadlin) about how to
pass options to the kernel at boot time.)
Note that, if you do this, the order of the hd* devices will be
rearranged which may require modification of fstab and other files.

depends on BLK_DEV_IDEDMA_PCI
help
This driver ensures (U)DMA support for Victroy66 SouthBridges for
SMsC with Intel NorthBridges. This is an Ultra66 based chipset.
The nice thing about it is that you can mix Ultra/DMA/PIO devices
and it will handle timing cycles. Since this is an improved
look-a-like to the PIIX4 it should be a nice addition.
If you say Y here, you need to say Y to "Use DMA by default when
available" as well.

Say Y here if you want to include enhanced support for various IDE
interface chipsets used on motherboards and add-on cards. You can
then pick your particular IDE chip from among the following options.
This enhanced support may be necessary for Linux to be able to
access the 3rd/4th drives in some systems. It may also enable
setting of higher speed I/O rates to improve system performance with
these chipsets. Most of these also require special kernel boot
parameters to actually turn on the support at runtime; you can find

config BLK_DEV_HD_ONLY

depends on BLK_DEV_IDE=n
---help---
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
Disk-HOWTO, available from

This driver adds up to 4 more EIDE devices sharing a single
interrupt. This add-on card is a bootable PCI UDMA controller. Since
multiple cards can be installed and there are BIOS ROM problems that
happen if the BIOS revisions of all installed cards (three-max) do
not match, the driver attempts to do dynamic tuning of the chipset
at boot-time for max-speed. Ultra33 BIOS 1.25 or newer is required
for more than one card. This card may require that you say Y to
"Special UDMA Feature".
If you say Y here, you need to say Y to "Use DMA by default when
