I can try to connect serial port to another machine and log everything

hmm, so far i was unable to get any data over serial from the machine. I 
tried setting "serial console redirect" to com1, but no output at all. I 
would like to have option to enter bios setup via serial if possible or 
at least access dfly as early as possible during boooting or while being 
  stuck in something like "syncing disks...".Can I actually do 
something there while watching this remotely via serial console?



Also, would some watchdog thing help in this case to at least restart 
the machine if some userland program was not updating its timer? Or 
maybe this:

# Set the amount of time (in seconds) the system will wait before
# rebooting automatically when a kernel panic occurs.  If set to (-1),
# the system will wait indefinitely until a key is pressed on the
# console.
options         PANIC_REBOOT_WAIT_TIME=16
hmm, this is already default. any other option to force machine to 
reboot itself anyway?
