IME, a failing CMOS battery usually causes that sort of problem only when power-cycling the system. If the "hard reboot" was done using a "reset" button, without having to turn off the power, it's more likely that whatever caused FreeBSD to freeze also corrupted the CMOS contents. One easy way to find out is to shut down normally, power off, leave it off for a couple of minutes, then turn it back on. If it is a battery problem the BIOS will be complaining about the CMOS again, due to power having been off, even though the shutdown was clean. Then you get to hope that the CMOS in fact has a replaceable battery, not one of those CMOS-and-battery-all-in-one-package things that some manufacturers have been known to use. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
