Help text

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 Documentation/ide/ide.txt. For detailed information about hard drives, consult the Disk-HOWTO and the Multi-Disk-HOWTO, available from

To fine-tune ATA/IDE drive/interface parameters for improved performance, look for the hdparm package at <>.

To compile this driver as a module, choose M here and read Documentation/ide/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.
