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.
