But why no do it? > We have a number of Dell PowerEdge 2950's that we boot using the built in SOL, which does run over IP as we use it across a routed VPN backbone (server in the data center, console in the office). We have found that the IPMI serial port is connected to the system as COM2, which we select in the bios configuration. We then set device.hints so that the freebsd console is set to use the same port. We use the open source ipmitool to access the ipmi controller, and serial port, on the system. Tom
