(no prompt) behaviour - it is now possible to "boot net:dhcp -a" and then say "disk" at the "Boot:" prompt - result should be equivalent to "boot disk", but the ofwboot was loaded from the network. While there fix a few minor errors, and one significant: if the "a" partition should not start at the beginning of the disk, the previous code failed to read a disklabel. Use the "c" partition now to find the disklabel now always.
