If the screen happens to be correct: - go into Procomm, ALT-D, 3 (call ncoast) - the dial times counts off ca. 3 "seconds" for every second on the clock. Again, a second reboot cures it. From what I've seen, a CTRL-ALT-DEL in Minix bypasses some of the warm-reboot code, leaving the clock and 6845 registers uninitialized. It's notable that a reboot from DOS has ca. 2 seconds of "dead time", whereas there is no dead time in a Minix reboot. Maybe I should look at it, but as yet I haven't even managed to get time to load Minix 1.2 into my machine (it's in a cpio file on ncoast). -- Brandon S.
