May I append that with those rebuilt bootblocks it works very fine?
We just replaced a VGA display and a keyboard by a T switch and some
serial cables, it works fine and we can use the same terminal for
two different machines (one's an older System V based machine, the
other our FreeBSD box running 2.0.5-RELEASE.)
But I made the experience that the kernel likes to go to single-user
mode when there's no terminal connected. I found a work-around in
connecting DSR and DTR at the machine's side of the serial line.
Is there any better way? In my humble opinion, the kernel should
ignore if there isn't any terminal present at boot time.
Or did I just miss something?
Bye,
Martin
