Not sure whether Dell hardware has any special management features, but on
generic server hardware, I always make sure BIOS console redirection is
enabled (gives you BIOS access), and that it's set to stop redirecting once
the OS boots.
Generally you will have network access (ssh or so) to a console server in the
datacentre which presents the FreeBSD system's console.
It's much easier to make sure you have an install CD which has the serial
console enabled - download an ISO image, unpack it, add
to loader.conf and rebuild the ISO image, making it bootable. There was a
thread about this a few months ago when Martin McCormick asked the question -
there are a couple of tricky issues with getting the ISO unpacked and rebuilt
without it doubling in size.
If you do this, you'll see the boot process from the Beastie menu onwards
(from which you can drop back to the loader if you need to), and it'll boot
Do the install normally. At the end, before exiting, I normally go to the
config menu to edit /etc/ttys - to make sure I get a login on the serial
console even if networking is stuffed for some reason.
Feel free to give me a shout if you want more details.
