Over the last few months I started noticing that my FreeBSD/amd64 desktop box would often come up with a date of Jan 1, 2008 after boot. Presumably the CMOS battery was dying and the motherboard picked a date from its year of manufacture. So I replaced the CR2032 battery on the motherboard and reapplied the BIOS settings that had been lost during the change. Unfortunately, I'm still greeted with atrtc0: WARNING: Battery failure indication Invalid time in real time clock. Check and reset the date immediately! Incongruously, the RTC time is actually correct. Well, off by a minute or so. Clearly the new battery is good. I guess this is more a PC question, but how do I get the RTC to indicate a valid time again? The motherboard manual (Asus) is rather silent on the whole issue of CMOS battery replacement. -- Christian "naddy" Weisgerber naddy@mips.inka.de
