Since you need a console driver to run DDB on, things are more
complicated if the console driver itself is failing. You might remember
the use of a serial console (either with modified boot blocks, or by
specifying -h
at the Boot:
prompt),
and hook up a standard terminal onto your first serial port. DDB works
on any configured console driver, including a serial
console.
