No idea, but I have a similar story... Kept hearing backup beeps, like from a heavy truck. Very faint, nowhere close. Could still hear 'em on the porch, a little louder, but where?? No idea. Couldn't tell. 24 hours a day. Must be the gravel pit or the sewage plant, a mile in either direction. Maybe where they're replacing gas pipeline across the road and down the way?? Maybe from the refinery across the river?? I can hear their noon chimes... Eventually became deaf to the beeps. A whole year later, the power goes out and the beeps stop. [At which point I noted that the #1 UPS was dead and needs replaced.] Turns out it was Moonbase (DOOM computer) ... somehow the CPU overheat alarm had gotten turned on, but it was so faint that it didn't register as IN THE DAMN HOUSE, especially since it sorta projected out the back of the box and through the wall (thus louder on the porch than right next to it). Turned off CPU overheat alarm in BIOS. No more beeps!! Moonbase does not overheat, far from it. Dunno why the alarm setting was on. Probably hadn't looked in the BIOS in ten years, let alone fiddled with anything. Mind of its own? too many dead hellspawn gumming up its brain?? þ RNET 2.10U: ILink: Techware BBS þ Hollywood, Ca þ www.techware2k.com --- QScan/PCB v1.20a / 01-0462 * Origin: ILink: CFBBS | cfbbs.no-ip.com | 856-933-7096 (454:1/1) .
