Ernest, if you have more than one core enabled I can _guarantee_ that your IOC 
is not going to run properly.  Our vxWorks OSD code is not ready for SMP 
operation yet, it needs someone to go through it with a fine tooth-comb, which 
might be a good Codeathon project for one of your guys.

It's not going to be as simple as that.

Please try running the libCom test suite on this CPU first:
    cd "/path/to/epics/base"
    ld 0,0, "bin/vxWorks-xxx/vxTestHarness.munch"
    epicsRunLibComTests

Any test failures in the results should give a few ideas of places that will 
need a closer look.
