Please note that if this driver is built into the kernel or loaded before other ATA (IDE or libata) drivers and the controller is located at legacy ports, this driver may grab those ports and thus can prevent the controller specific driver from attaching. Also, currently, IDE generic doesn't allow IRQ sharing meaning that the IRQs it grabs won't be available to other controllers sharing those IRQs which usually makes drivers for those controllers fail.

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).

(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.

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. Note that, if you do this, the order of the hd* devices will be rearranged which may require modification of fstab and other files.

This driver adds up to 4 more EIDE devices sharing a single interrupt. The HPT366 chipset in its current form is bootable.

It is safe to say Y to this question. config BLK_DEV_CS5535 tristate "AMD CS5535 chipset support" depends on X86 && !X86_64 select BLK_DEV_IDEDMA_PCI help Include support for UDMA on the NSC/AMD CS5535 companion chipset. This will automatically be detected and configured if found. It is safe to say Y to this question. config BLK_DEV_CS5536 tristate "CS5536 chipset support" depends on X86_32 select BLK_DEV_IDEDMA_PCI help This option enables support for the AMD CS5536 companion chip used with the Geode LX processor family. If unsure, say N. config BLK_DEV_HPT366 tristate "HPT36X/37X chipset support" select BLK_DEV_IDEDMA_PCI help HPT366 is an Ultra DMA chipset for ATA-66. HPT368 is an Ultra DMA chipset for ATA-66 RAID Based. HPT370 is an Ultra DMA chipset for ATA-100. HPT372 is an Ultra DMA chipset for ATA-100. HPT374 is an Ultra DMA chipset for ATA-100. 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. 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_JMICRON tristate "JMicron JMB36x support" select BLK_DEV_IDEDMA_PCI help Basic support for the JMicron ATA controllers. For full support use the libata drivers. config BLK_DEV_SC1200 tristate "National SCx200 chipset support" select BLK_DEV_IDEDMA_PCI help This driver adds support for the on-board IDE controller on the National SCx200 series of embedded x86 "Geode" systems. config BLK_DEV_PIIX tristate "Intel PIIX/ICH chipsets support" select BLK_DEV_IDEDMA_PCI help This driver adds explicit support for Intel PIIX and ICH chips.
