the technology, i think, is not very popular, but can come VERY handy.
Intel AMT Serial over LAN (SOL, why is it called 'over LAN' if it is
really
'OVER IP'?) allows to boot into BIOS of a remote machine
and even, as seen in their demo, can be used to control MS DOS prompt.
well because it isnt using IP, besides SOIP is uninspiring :)
Wait.. how so? I was sure that the whose SOL (IPMI) protocal is running
over
IP and i can REMOTELY (e.g. from anoth planet with IP connection) access
the machine in the data center. If i can do such thing, then it DOES run
over IP
eventually. Isn't it?
Anyway, nobody said anothing about getting freebsd boot prompt over SOL.
My guess, that this is THE MOST usefull usage of SOL for remote upgrades.
I understand that this is not as simple as sending data to UART. THis is
must
be done explicitely in the boot loader, i thinks. 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.
