To change it you'll have to mount / frow its real >device, but you should be able to find that by hand. ( You probably >want mount /dev/sd0a / ). To enable the boot from sd1, try: # mount /dev/sd1a / # mount /dev/sd1e /usr # vi /etc/fstab Then make sure that the devices are sd1a, sd1b, sd1e and not sd0a, sd0b, and sd0e. If these are wrong, change them and reboot. Otherwise, let me know what /etc/fstab looks like. I have done this after moving an IDE FreeBSD boot drive to wd1, but it is probably the same for sd1.
