I did as you suggested, pulled one chip at a time until I thought I found a culprit and pulled it - and the machine would boot. Funny thing was, I put the case back together and then it wouldn't even boot - not even to the smiley face. I pulled out the match (D1/D2) too, and it worked fine... for a while.
Now, it's basically the same issue: freezes at the smiley face - if it even gets that far. Sometimes I get Finder Unexpectedly Quit error right after boot. I tried the Tech Tool RAM check and the Newer utility to no avail. I've had 5-6 Macs and had never had RAM issues like this - is this a Umax thing?
I dunno... looks like a 9600, which my upgrade card fits, goes for under $100 on Ebay.

I was wondering if anyone on the list had similar symptoms with their Umax S900. I have an S900, Sonnet G3 450Mhz upgrade card, AudioWerk PCI audio card, 2 Megawolf serial PCI cards, 4 MIDI serial int and a JL Cooper Media Station that pull power from the S900 and of course the video card running Mac OS 8.6 w/ 192Mb RAM.
What I am experiencing is freeze ups during start-up: sometimes before the smiley face, sometimes during the smiley face, sometimes a bus error during extension load. Thinking it was an extension conflict, I purchased Conflict Catcher, but with no luck. It happens with the standard 8.6 extension set.
The issue: it will freeze 2-3 times on a boot when the machine hasn't been running for a certain period, after that 2-3 freezes it comes up, once up, I turn it off - it always comes up without freezing. A re-start never freezes.
Does this sound like a power supply on the verge of failure? My guess between the Media Control Station, MIDI interfaces, G3 card - I'm pulling more power than normal and given it's age. Any Ideas? Thanks!
Bad ram chip is what comes to mind. The tell tell sign no freezes at re-start. Mac doesn't check ram when re-starting but always does from a boot up. Try removing ram chips one at a time until you find the one causing the problem. Power supply shouldn't make a difference if booting or re-starting should work the same either way. best of luck Will S
