Sure, let's try that. Maybe this is the better way to go anyways. I just learned that disabling iLo2 doesn't necessarily disable the management firmware on the network device. For this to be a meaningful test though, we need to verify that the driver sign-on messages have a line that reads "ASF[0]" on eth1.

Thanks.
