This probably isn't the best forum for this question, but I know several 'fritterers dabble in the Dark Side a bit, so I'm hoping somebody's got an answer for me.
I came by an older Intel server last week that has trouble running for any length of time. It's a dual proc. 850MHz PIII that's decked out with a gig of RAM, onboard LVD Ultra-SCSI, two PCI SCSI cards, and a slew of LVD SCSI drives. It's running NT-4 Server, but if I can get it to run consistently I'll likely load a copy of Linux (Ubuntu or Mandrake most likely) on it and use it as a home server for my Macs at home.
Most of the time it'll seem to fire up fine when you mash on the power button, but usually it'll get only part way through the boot sequence then silently start the boot sequence from scratch, like you'd hit the reset button. On the occasions that it does fully boot into NT4, it'll seem to run fine for a while, then BOOM, it restarts. No rhyme or reason as to when it happens, it just happens. The fans continue to run and the drives continue to spin, but it just reboots. Oh, and sometimes when it boots up it complains about one of the processors being offline, but usually it boots without complaint & shows both processors running just fine.
I'm thinking it's maybe a flaky power supply -- The voltage on one of the outputs dips slightly on occasion and the machine just stops -- but I could also see this having something to do with a bad processor or logic board. Or could it be something as simple as a dead BIOS battery on the logic board? Anybody have any advice for what to look for to troubleshoot this dog, or can you refer me to somewhere on the web that might be a good resource for a Mac-centric guy trying to figure out the trouble with an oddball machine like this? Or am I better off scavenging the useful parts from it & dumping the rest?
