Machine is i386 pentium 4
I'm using a terminal off of com port 1 
I changed the ttyd0 to ttyu0 in /etc/ttys
rebuilt /sys/boot and kernel.
But now I have no comconsole
When the machine boots I get :
the loader message, but no more
I also use the console for the kernel debugger
Don't even get a login prompt on it 
Any Ideas
Thanks
Manfred
