First of all, the CD boot process doesn't pick up the boot.config. Secondly, many motherboards use a BIOS which causes the -P test to fail. What you can do is create boot/loader.conf on the CD image containing console="comconsole" > > Sure that's enough? ttys is still going to mark the ttyd0 line as > "off" and won't present a tty/login then. Yes, it is. You don't need a login for an installation. You do need to make sure you enable the correct serial port (usually ttyd0, as you point out) in /etc/ttys before you reboot at the end of the installation. > I think it's more complicated than that.

One day I will make time to sit down and work out how to do it properly on a CD. Jonathan
