I was trying to make the boot process 100% independent of the VGA console at one stage. To the best of my knowledge, boot0 doesn't know anything about serial, unless someone's using my boot0sio hack (which I haven't committed, btw; it was very specific - you have only 512 bytes to play with in the MBR, and I understand people had problems with jhb's 1024 byte boot0). boot2 is probably the more interesting part, it does make assumptions if BOOT_COMCONSOLE_SPEED wasn't specified in the make, and loader takes its cue from that up until it sees 'console' in loader.conf[.local]. One of the limitations here is that there can only be one console. Anything else would be something of a hack to get boot2 and loader to tee their output to two independent devices. BMS
