Swap the SBS VME controllersSwap the SBS PCI cardsRun test programs which used to work

☺Test each board using Mike’s test-stand set up

Potential Location of Problem

• Hardware– SBS VME controller– SBS PCI card– TF backplane

• Software– Test program (unlikely)– SBS driver– System files

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
