Your original issue might also be endian related, since you're using an Intel 
CPU which is LE while most vxWorks users run on PowerPC which is BE (however I 
don't think you're the first Intel user so this might be a total red herring).

Thanks, I thought that would happen.  I've added this task to my list.
