Catching the trace is easy if you've got a second computer you can use as a serial terminal (e.g. with kermit). Hook it up onto your first serial line (ttyd0/COM1:), setup kermit for 9600 baud, and enable session logging. As soon as the ``boot:'' prompt appears, enter `-h'. This will turn your kermit session into the system console. I think you can compile a kernel, right? Could i convince you to read the section about kernel debugging in the handbook, and try to build a kernel with DDB enabled? Of course, this will only be useful if you can log your session, so you could mail or post relevant traces. This should give you at least a stack trace of where the system crashes. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
