I'm now as a thumbrule (well, no servers older tan, say, 6-8 years) use output of grep uart /var/run/dmesg.boot and, usually, IPMI/SOL is the last one from the output; also, you can use port/irq from there in corner cases -- Sincerely, D.Marck [DM5020, MCK-RIPE, DM3-RIPN] [ FreeBSD committer: marck@FreeBSD.org ] ------------------------------------------------------------------------ *** Dmitry Morozovsky --- D.Marck --- Wild Woozle --- marck@rinet.ru *** ------------------------------------------------------------------------
