The problem became apparent when I took the machine down after it had been switched on and running perfectly for about two years (as a server). I'd had a G3 upgrade in it that I wanted to try in another machine (it works), and when I put it all back together again it wouldn't boot from the Adaptec SCSI card that it came with. Not a problem, I thought, I'd just boot from something else and reset the startup disk. However, I've never been able to get it to boot again, although as I say the startup chime is good and Open Firmware seems fine so there can't be very much wrong. It just seems to me that during those two years something may have duffed out that is needed for the boot process to run, but I don't know what to try. ROM replacement? Mobo from eBay? I don't want to abandon the machine as it so nearly seems to work! ______________ ou may well have bumped a CPU card or a RAM DIMM. The machine sees that on startup and balks Reseat the cards and if that does not work pull everything and use electronic contact cleaner on all slots and card edges. An old toothbrush will help. Make everything sparkly and reinstall. I assume all drive IDs and termination are OK. And have you tried starting with extensions off? The RAM DIMMS are matched for size and speed. No odd chips?
