Better yet, patch your bootblocks to force a serial console. The bootblocks already allow you to toggle between the serial and graphics console with -h; all you need is changing the default. This gives you the added feature that you can boot an alternate kernel even with a serial console. cd /sys/i386/boot/biosboot vi Makefile # remove a comment character there make all install disklabel -B sd0 That's all... -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
