3. Done Swap the SBS VME controllers Swap the SBS PCI cards Run test programs which used to work ☺Test each board using Mike’s test-stand set up

4. Potential Location of Problem Hardware –SBS VME controller –SBS PCI card –TF backplane Software –Test program (unlikely) –SBS driver –System files

5. To Do SBS PCI card/ VME controller - Check using Mike’s PC and peripheral crate TF backplane - Check using Mike’s PCI card and VME controller Software - Scan viruses and check system files and driver
