I'll boot it back up and check but I am trying to see the full dmesg  
log for the system after a boot. I don't think starting those after  
the system has booted will give me what I am looking for. I can issue  
the dmesg command but it is truncated so I don't see the full output,  
I only see however much the buffer size is set for and can't figure  
out a way to increase the size of the buffer.
