Just add the line "console=comconsole" in /boot/loader.conf and you have your
1st sio as console with 9600boud.
If you need loader interactivity, instead create the file /boot.config with
the two characters "-h" in the first line, then you don't need to set the
console in loader.conf.
If you want to have a different console speed see the sysctl
"machdep.conspeed". You can set that via sysctl.conf.
But if you also want a different port or serial control before login see the
following options in /etc/make.conf:
BOOT_COMCONSOLE_PORT= 0x2F8 # Use sio1 (com2)
You have to rebuild your kernel and the loader. For the latter go
to /usr/src/sys/boot/i386 and 'make clean' 'make depend' 'make install'
If you want to login in multiuser mode edit /etc/ttys and make sure you have a
line like that:
ttyd0 "/usr/libexec/getty std.115200" cons25 on secure

No idea, sorry
