This is the only way where Ctrl-Alt-Esc is being respected. Within DDB, you could type ``panic'', and hopefully get a core dump. However, if all interrupts are blocked, this doesn't help you, while the NMI button should still be honored. Dumping itself turns the disk driver into polled mode, so it should even work with jamming interrupt lines. -- 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. ;-)
