# # IDE ATA ATAPI Block device driver configuration # # Andre Hedrick <andre@linux-ide.org> # menu "ATA/ATAPI/MFM/RLL support" config IDE tristate "ATA/ATAPI/MFM/RLL support" ---help--- 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. To compile this driver as a module, choose M here: the module will be called ide. For further information, please read <file:Documentation/ide.txt>. If unsure, say Y. if IDE config IDE_MAX_HWIFS int "Max IDE interfaces" depends on ALPHA || SUPERH default 4 help This is the maximum number of IDE hardware interfaces that will be supported by the driver. Make sure it is at least as high as the number of IDE interfaces in your system. config BLK_DEV_IDE tristate "Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support" ---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/>. To compile this driver as a module, choose M here and read <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. if BLK_DEV_IDE comment "Please see Documentation/ide.txt for help/info on IDE drives" config BLK_DEV_IDE_SATA bool "Support for SATA (deprecated; conflicts with libata SATA driver)" default n ---help--- 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 a few first-generation SATA controllers. In order to eliminate conflicts between the two subsystems, this config option enables the IDE driver's SATA support. Normally this is disabled, as it is preferred that libata supports SATA controllers, and this (IDE) driver supports PATA controllers. If unsure, say N. config BLK_DEV_HD_IDE bool "Use old disk-only driver on primary interface" depends on (X86 || SH_MPC1211) ---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. config BLK_DEV_IDEDISK tristate "Include IDE/ATA-2 DISK support" ---help--- This will include enhanced support for MFM/RLL/IDE hard disks. If you have a MFM/RLL/IDE disk, and there is no special reason to use the old hard disk driver instead, say Y. If you have an SCSI-only system, you can say N here. To compile this driver as a module, choose M here: the module will be called ide-disk. Do not compile this driver as a module if your root file system (the one containing the directory /) is located on the IDE disk. If unsure, say Y. config IDEDISK_MULTI_MODE bool "Use multi-mode by default" help If you get this error, try to say Y here: hda: set_multmode: status=0x51 { DriveReady SeekComplete Error } hda: set_multmode: error=0x04 { DriveStatusError } If in doubt, say N. config BLK_DEV_IDECS tristate "PCMCIA IDE support" depends on PCMCIA help Support for outboard IDE disks, tape drives, and CD-ROM drives connected through a PCMCIA card. config BLK_DEV_IDECD tristate "Include IDE/ATAPI CDROM support" ---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 <http://lilo.go.dyndns.org/>. To compile this driver as a module, choose M here: the module will be called ide-cd. config BLK_DEV_IDETAPE tristate "Include IDE/ATAPI TAPE support (EXPERIMENTAL)" depends on EXPERIMENTAL help If you have an IDE tape drive using the ATAPI protocol, say Y. ATAPI is a newer protocol used by IDE tape and CD-ROM drives, similar to the SCSI protocol. If you have an SCSI tape drive however, you can say N here. You should also say Y if you have an OnStream DI-30 tape drive; this will not work with the SCSI protocol, until there is support for the SC-30 and SC-50 versions. If you say Y here, the tape drive will be identified at boot time along with other IDE devices, as "hdb" or "hdc", or something similar, and will be mapped to a character device such as "ht0" (check the boot messages with dmesg). Be sure to consult the <file:drivers/ide/ide-tape.c> and <file:Documentation/ide.txt> files for usage information. To compile this driver as a module, choose M here: the module will be called ide-tape. config BLK_DEV_IDEFLOPPY tristate "Include IDE/ATAPI FLOPPY support" ---help--- 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 for PD-CD/CDR drives is available if you answer Y to "SCSI emulation support", below). If you say Y here, the FLOPPY drive will be identified along with other IDE devices, as "hdb" or "hdc", or something similar (check the boot messages with dmesg). To compile this driver as a module, choose M here: the module will be called ide-floppy. config BLK_DEV_IDESCSI tristate "SCSI emulation support" depends on SCSI ---help--- WARNING: ide-scsi is no longer needed for cd writing applications! The 2.6 kernel supports direct writing to ide-cd, which eliminates the need for ide-scsi + the entire scsi stack just for writing a cd. The new method is more efficient in every way. 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 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. 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. config IDE_TASK_IOCTL bool "IDE Taskfile Access" help This is a direct raw access to the media. It is a complex but elegant solution to test and validate the domain of the hardware and perform below the driver data recover if needed. This is the most basic form of media-forensics. If you are unsure, say N here. comment "IDE chipset support/bugfixes" config IDE_GENERIC tristate "generic/default IDE chipset support" default y help If unsure, say Y. config BLK_DEV_CMD640 bool "CMD640 chipset bugfix/support" depends on 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>. config BLK_DEV_CMD640_ENHANCED bool "CMD640 enhanced support" depends on BLK_DEV_CMD640 help This option includes support for setting/autotuning PIO modes and prefetch on CMD640 IDE interfaces. For details, read <file:Documentation/ide.txt>. If you have a CMD640 IDE interface and your BIOS does not already do this for you, then say Y here. Otherwise say N. config BLK_DEV_IDEPNP bool "PNP EIDE support" depends on PNP help If you have a PnP (Plug and Play) compatible EIDE card and would like the kernel to automatically detect and activate it, say Y here. config BLK_DEV_IDEPCI bool "PCI IDE chipset support" if PCI default BLK_DEV_IDEDMA_PMAC if PPC_PMAC && BLK_DEV_IDEDMA_PMAC help Say Y here for PCI systems which use IDE drive(s). This option helps the IDE driver to automatically detect and configure all PCI-based IDE interfaces in your system. config IDEPCI_SHARE_IRQ bool "Sharing PCI IDE interrupts support" depends on PCI && BLK_DEV_IDEPCI help Some ATA/IDE chipsets have hardware support which allows for sharing a single IRQ with other cards. To enable support for this in the ATA/IDE driver, say Y here. It is safe to say Y to this question, in most cases. If unsure, say N. 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. If in doubt, say N. config BLK_DEV_GENERIC tristate "Generic PCI IDE Chipset Support" depends on BLK_DEV_IDEPCI config BLK_DEV_OPTI621 tristate "OPTi 82C621 chipset enhanced support (EXPERIMENTAL)" depends on PCI && BLK_DEV_IDEPCI && EXPERIMENTAL help This is a driver for the OPTi 82C621 EIDE controller. Please read the comments at the top of <file:drivers/ide/pci/opti621.c>. config BLK_DEV_RZ1000 tristate "RZ1000 chipset bugfix/support" depends on PCI && BLK_DEV_IDEPCI && X86 help The PC-Technologies RZ1000 IDE chip is used on many common 486 and Pentium motherboards, usually along with the "Neptune" chipset. Unfortunately, it has a rather nasty design flaw that can cause severe data corruption under many conditions. Say Y here to include code which automatically detects and corrects the problem under Linux. This may slow disk throughput by a few percent, but at least things will operate 100% reliably. config BLK_DEV_SL82C105 tristate "Winbond SL82c105 support" depends on PCI && (PPC || ARM) && BLK_DEV_IDEPCI help If you have a Winbond SL82c105 IDE controller, say Y here to enable special configuration for this chip. This is common on various CHRP motherboards, but could be used elsewhere. If in doubt, say Y. config BLK_DEV_IDEDMA_PCI bool "Generic PCI bus-master DMA support" depends on PCI && BLK_DEV_IDEPCI ---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> and the file <file:Documentation/ide.txt> for more information. It is safe to say Y to this question. if BLK_DEV_IDEDMA_PCI config BLK_DEV_IDEDMA_FORCED bool "Force enable legacy 2.0.X HOSTS to use DMA" help This is an old piece of lost code from Linux 2.0 Kernels. Generally say N here. config IDEDMA_PCI_AUTO bool "Use PCI DMA by default when available" ---help--- 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! It is normally safe to answer Y to this question unless your motherboard uses a VIA VP2 chipset, in which case you should say N. config IDEDMA_ONLYDISK bool "Enable DMA only for disks " depends on IDEDMA_PCI_AUTO help This is used if you know your ATAPI Devices are going to fail DMA Transfers. Generally say N here. config BLK_DEV_AEC62XX tristate "AEC62XX chipset support" help This driver adds explicit support for Acard AEC62xx (Artop ATP8xx) IDE controllers. This allows the kernel to change PIO, DMA and UDMA speeds and to configure the chip to optimum performance. config BLK_DEV_ALI15X3 tristate "ALI M15x3 chipset support" help This driver ensures (U)DMA support for ALI 1533, 1543 and 1543C onboard chipsets. It also tests for Simplex mode and enables normal dual channel support. If you say Y here, you also need to say Y to "Use DMA by default when available", above. Please read the comments at the top of <file:drivers/ide/pci/alim15x3.c>. If unsure, say N. config WDC_ALI15X3 bool "ALI M15x3 WDC support (DANGEROUS)" depends on BLK_DEV_ALI15X3 ---help--- This allows for UltraDMA support for WDC drives that ignore CRC checking. You are a fool for enabling this option, but there have been requests. DO NOT COMPLAIN IF YOUR DRIVE HAS FS CORRUPTION, IF YOU ENABLE THIS! No one will listen, just laugh for ignoring this SERIOUS WARNING. Using this option can allow WDC drives to run at ATA-4/5 transfer rates with only an ATA-2 support structure. SAY N! config BLK_DEV_AMD74XX tristate "AMD and nVidia IDE support" help This driver adds explicit support for AMD-7xx and AMD-8111 chips and also for the nVidia nForce chip. This allows the kernel to change PIO, DMA and UDMA speeds and to configure the chip to optimum performance. config BLK_DEV_ATIIXP tristate "ATI IXP chipset IDE support" depends on X86 help This driver adds explicit support for ATI IXP chipset. This allows the kernel to change PIO, DMA and UDMA speeds and to configure the chip to optimum performance. Say Y here if you have an ATI IXP chipset IDE controller. config BLK_DEV_CMD64X tristate "CMD64{3|6|8|9} chipset support" help Say Y here if you have an IDE controller which uses any of these chipsets: CMD643, CMD646, or CMD648. config BLK_DEV_TRIFLEX tristate "Compaq Triflex IDE support" help Say Y here if you have a Compaq Triflex IDE controller, such as those commonly found on Compaq Pentium-Pro systems config BLK_DEV_CY82C693 tristate "CY82C693 chipset support" help This driver adds detection and support for the CY82C693 chipset used on Digital's PC-Alpha 164SX boards.

This will automatically be detected and configured if found. It is safe to say Y to this question. config BLK_DEV_HPT34X tristate "HPT34X chipset support" help This driver adds up to 4 more EIDE devices sharing a single interrupt. The HPT343 chipset in its current form is a non-bootable controller; the HPT345/HPT363 chipset is a bootable (needs BIOS FIX) PCI UDMA controllers. This driver requires dynamic tuning of the chipset during the ide-probe at boot time. It is reported to support DVD II drives, by the manufacturer. config HPT34X_AUTODMA bool "HPT34X AUTODMA support (EXPERIMENTAL)" depends on BLK_DEV_HPT34X && EXPERIMENTAL help This is a dangerous thing to attempt currently! Please read the comments at the top of <file:drivers/ide/pci/hpt34x.c>. If you say Y here, then say Y to "Use DMA by default when available" as well.

This driver adds up to 4 more EIDE devices sharing a single interrupt. The HPT366 chipset in its current form is bootable. One solution for this problem are special LILO commands for redirecting the reference to device 0x80. The other solution is to say Y to "Boot off-board chipsets first support" (CONFIG_BLK_DEV_OFFBOARD) unless your mother board has the chipset natively mounted. Regardless one should use the fore mentioned option and call at LILO or include "ide=reverse" in LILO's append-line. This driver requires dynamic tuning of the chipset during the ide-probe at boot. It is reported to support DVD II drives, by the manufacturer. config BLK_DEV_SC1200 tristate "National SCx200 chipset support" help This driver adds support for the built in IDE on the National SCx200 series of embedded x86 "Geode" systems config BLK_DEV_PIIX tristate "Intel PIIXn chipsets support" help This driver adds explicit support for Intel PIIX and ICH chips and also for the Efar Victory66 (slc90e66) chip.

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 available" as well. Please read the comments at the top of <file:drivers/ide/pci/pdc202xx_old.c>.

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.
