My RC3240 has become exquisitely sensitive to power glitches, or there has been a drastic increase in power glitches in one room, and I now need to have the machine reboot itself. A while ago I searched the manuals but did not find out how to set the machine to reboot itself after a power glitch or other failure. Is there one, and if so, what is it (and where in TM is it)?

Setting the PROM monitor "bootmode" variable equal to "c" is supposed to do this. (But even having done this, I've seen an M/2000 fail to autoboot cleanly after a power glitch.) You should be able to set the bootmode variable using "/etc/hwconf -s bootmode c" in a running system (although I've seen this fail to do anything in a 2030), or do it with "setenv bootmode c" next time you have the machine down at the PROM monitor. -- -------------------------------------------------------------------------- Laurence G.

Thanks. I recall doing this when I first got the machine about a year ago but it didn't work then. I will try it again as given above. There was something else that broke with the "c" option, but I don't remember what it is...I'll find out the hard way. dan -- dr. dan davison/dept. of biochemical and biophysical sciences/univ. of Houston/4800 Calhoun/Houston,TX 77054-5500/davison@uh.edu/DAVISON@UHOU Disclaimer: As always, I speak only for myself, and, usually, only to myself.

(But even having done this, I've seen an M/2000 fail to >autoboot cleanly after a power glitch.) I set bootmode to c on our 3240. It did try to reboot, but just after loading the kernel it gave an endless stream of unexpected fp interupt messages. Setting bootmode to w (warm vs. cold) fixed the problem. The machine still reboots after a crash or power outage. -stacy -- Brian Mulroney is at 15% in the polls and uunet!sobeco!stacy 17% of Canadians believe Elvis is alive stacy@sobeco.com
