To get kernel info output to the serial line (and lose it on the VGA line), in lilo.conf add: serial=0,38400n8 image=blah append="console=ttyS0,38400" and to get a vty on your serial line, in inittab add something like: s0:12345:respawn:/sbin/mingetty ttyS0 DT38400 ansi Then connect up the proper cable (Null modem for computer to computer) and run minicom or some other terminal program on it. > 2.

There's a few different things you can do (gdb?) to crash a system, you should be able to find that on google... but I wonder if that kernel config option "SysRq key" would help you here. Check the kernel stuff on that one.
