EIDE controllers and EIDE hard disks

Support knowledgebase (maddin_eide)

Symptom:

These are only some of the known problems. If the drive cannot be accessed for short periods of time or if you have the feeling that something "strange" happens with the harddrive, then this might also be a symptom.

Cause:

There are some EIDE disk controllers, whose chipsets are faulty or do not follow the standards. Some features like e.g. Busmaster DMA or similar are not correctly implemented either. This concerns some of the onboard controllers on motherboards, partially integrated in the PCI chipset. Here is a list of the controller chipsets (probably not complete):

CMD640, RZ1000, DTC-2278, HT 6560B, QDI QD6580, UMC 8672, ALI M1439 and ALI M1445, Promise DC4030, Intel FX430

Please read in any case pages 3-3 or 3-5 in the S.u.S.E. Linux 4.2 handbook both of them at the bottom (only available in german). Some chipsets have problems with DMA (Busmaster DMA), others cannot detect or serve the second IDE canal either. Besides, many controllers have problems to serialise the enquiries.

Solution:

During the installation

Please take the installation kernel IDE-3 or IDE-7. There, kernel support for the above mentioned chipsets is installed. Use (as long as the chipsets is known) the corresponding kernel parameter (handbook).

Should it still not run, please read the kernel boot messages through. The corresponding hint to the appeared problem should be there in ide0:.

In running system
