How can I setup Serial-Over-Lan (SOL) on FreeBSD 10.0 with a SuperMicro X9-SCM-F motherboard? There are a few resources out there but they contradict each other, are unclear, and don’t actually allow me to get SOL working past the boot loader.
Not enough rep to comment on the answer above, so:
I run FreeBSD 9.2 and Andrew's configuration above enables SOL on COM 3 for me on X8SIL-F / X8SIE-F, from BIOS to login prompt. It is completely based on his above answer but tested on 9.2 with GENERIC kernel--thank you, Andrew!
A few notes:
This is tested on FreeBSD 10.0-RELEASE, but will likely work on FreeBSD 9.x.
Above is the absolute minimum required to get this working. Various people (see “References” below) recommended or stated that they “needed” a slew of other settings which, for me, were not absolutely needed but did not impair SOL functionality either. They are:
Despite what the FreeBSD handbook seems to say, you should not need to compile a custom kernel.
Please note that many of these are wrong, out-of-date, or overzealous in setting options not actually needed.
