Experimental Physics and
Industrial Control System

Hi Rong,

As I recall that SIS support on Linux was used by some sites that had an SIS PCI to VME adapter.  It let a Linux PC talk to VME.  I doubt if that is still in use.  The other way to do it is to run Linux on a VME CPU.  That has been done, but I don't know any site currently using it.

Unfortunately, I am not aware of anything I would describe as "normal"
about VME support in Linux.  You may have a lot more work than you expect here.  :(

To start with, can you describe your hardware?  What sort of VME cards are present in your crate(s) ?
