If it's the right type of driver, the megarc port might be helpful.
Works on our Dells.

DRAC = console over network
IPMI = hardware monitoring
Open Manage = I have no clue

DRAC is irrelevant to FreeBSD.  Configure it in the BIOS (give it an
IP and the like) and you can use a web browser to get a console window.
(True console, so that you can access the BIOS during boot and

Install ipmitool and use it to access IPMI over the network.

We have a central machine that monitors all our servers via a Nagios
plugin to ipmitool.  I can't offer any advice on getting OpenIPMI

DRAC and IPMI are completely seperate.  There is some overlap, for example
both DRAC and IPMI can be used to monitor sensors and reboot the hardware.

DRAC is nice in that it gives you a spiffy web interface, as well as the
whole console over IP thing.  IPMI is nice because it's a standard that
can be programmed to, with ipmitool, for example.
