Enhanced IDE (EIDE) interfaces are supported, including support for UDMA and ATA/33, ATA/66, and so on for some controllers and compatible drives. Linux will detect these IDE interfaces:
CMD-640 (Support for buggy interfaces in kernel 2.2)
RZ1000 (Support for buggy interfaces in kernel 2.2)
Cyrix CS5530 MediaGX
FGI/Holtek HT-6560B VLB (Support for secondary interface in kernel 2.2)
Triton I (82371FB) (with busmaster DMA)
Triton II (82371SB) (with busmaster DMA)
Please see the IDE RAID controller section for information on IDE controllers with hardware RAID support.
Linux will work with standard IDE, MFM and RLL controllers. When using MFM/RLL controllers it is important to use ext2fs and the bad block checking options when formatting the disk.
ESDI controllers that emulate the ST-506 (MFM/RLL/IDE) interface will also work. The bad block checking comment also applies to these controllers.
Generic 8 bit XT controllers also work.
