If it happens to be already setup via the BIOS, then you may not need to
configure anything w/ ipmi-config.

There is nothing that different from using IPMIView, except it's all on
the command line now.  You need to input host, username, password, etc.
on the command line for the FreeIPMI tool you want to use.  For sensors

ipmi-sensors -h HOST -u username -p password

would get you sensors output.  Similar options with ipmi-sel, ipmi-fru,
ipmipower, ipmiconsole, etc.  Since FreeIPMI tries to work with every
motherboard from out there, and some vendors implement IPMI incorrectly,
sometimes workarounds need to be specified on the command line to work
w/ specific motherboards.  Those workarounds can be found in the
