I think the cold reset will set its state back to the HW settings.  In 
other words if you have configured it via ipmitool and those configs
are not reflected in the BMC HW settings, then I believe after a cold
reset the BMC goes back to its settings.

In summary, make sure you BMC settings are correct.
