NCR and Ultra

Applies to

Kernel: Versions since 2.0.31

Symptom:

An NCR SCSI controller refuses to run in ultra mode.

Cause:

Some NCR controllers are capable and some are not. Nevertheless none of them does it automatically.

Solution:

You need to use the BSD driver; see /usr/src/linux/drivers/scsi/README.ncr53c8xx: 

        Example:
        
        lilo: linux root=/dev/hda2 ncr53c8xx=tags:4,sync:10,debug:0x200
        
        und:
        
        Ultra SCSI support
           Only apply to 860 and 875 controllers.
           Have no effect with other ones.
              ultra:y    enabled
              ultra:n    disabled
        
        Should work with:
        
        linux ncr53c8xx=ultra:y
        
        Well, only for the 860 and 875. The 895 says:
        
        (1) The 895 chip is supported 'on paper'.
