This does not seem to be necessary with FreeBSD 8.1 and above. >How-To-Repeat: >Fix: I have tested this on a FreeBSD 8.1 system (specifically the pfSense 2.0.1 distribution) and a Supermicro motherboard redirecting the console to the serial over lan port. The BIOS has a "redirect console to serial port" option, which seems to take care of redirecting the boot block and boot loader output to the serial port. To make the kernel send output to COM3, which is the SOL port on the Supermicro motherboard, simply add these lines to /boot/loader.conf: hint.uart.2.at="isa" hint.uart.2.port="0x3E8" hint.uart.2.flags="0x10" hint.uart.0.flags="0x00" Use these along with any other settings you have to turn on the serial console in loader.conf or boot.config. There is no need to recompile anything with this configuration. >Release-Note: >Audit-Trail: >Unformatted:
