Thank you! Good info. Yes, I have partitioned the drive with the first partition of 7.65GB and the other three then spaced themselves equally with approx 28GB. I installed OS 10.2.8 on the first partition and it worked fine. I then installed OS 9.0 on the second partition. Still worked fine. I could switch back and forth and run applications under both systems including classic in OSX. I had downloaded my entire 4GB hard drive onto an external 80G USB drive before doing anything. At that point I had my long running 9.2.2 in place with 192MB of RAM and 6MB of VRAM. I had replaced my PRAM battery just a few months before so I knew that was OK. Anyhow, to shorten the story, I tried to install the Harmoni with two new 256MB ram modules aboard all at once. The directions said I would hear a not the usual chime but a "long tone" followed after maybe 45 seconds or so by 7 beeps. Well, I didn't hear the chime but a rather long nasty sound like an electronic raspberry followed by 3 beeps and then nothing - just a gray screen. Well, the directions from Sonnet warned that any interruption in this first startup after installing the Harmoni board might put the iMac "into a state that can be very difficult to get out of". I waited maybe 10 minutes but no more activity in the HD or on the screen so I tried all the keyboard combinations and even the pinhole reset switch but not even that made any difference. Finally, I pulled the plug. When I plugged back in and restarted, I got the same raspberry but this time it came up with the OF screen. I put the original cpu board back in with the new RAM chips and restarted. Raspberry and no startup. Put old RAM back in the the iMac came up just fine. I swapped RAM until I isolated the bad module. Tried the Harmoni install again and this time had a normal chime and a partial bootup that hung as it was trying to load. I called Sonnet and they said the Harmoni was bad and they'd replace it. Put the original CPU back in with 384MB of memory and the system worked fine for a few days until I ventured to try to put my old system folder back into my OS9 system. That's when it went into OF and I haven't been able to get back to anything since.
Guess I didn't shorten the story very well, did I? Anyhow, the new RAM and the new Harmoni have arrived and I am ready to forge ahead again! I must be a glutton for punishment! All this just because I needed a firewire port. I know, I know----I shoulda just sprung for a new or newer machine already built that way!!! But, I'm an inveterate gageteer and this has become a personal thing, yaknow? Thanks to all for your friendly help!!!

Just a thought, I notice on your first posting, you mentioned you replaced the drive... you were sure to partition it in such a way that the first partition is less then 8 GB, and then you installed OS X on that partition correct? (this assumes you were installing OS X at all, you don't mention if you were, if you are not, and are staying with OS 9 or earlier, then the partition issue is irrelivant). Also, I ran into the same problem with a Bondi that I put OS X on. I had to not only issue the mac-boot command, but all "reset-all" or "reset-nvram" (I don't remember which). I had to do the reset BEFORE the mac-boot. That would let it boot properly, however, every time the iMac was turned off (only seemed to happen when turned off, a reboot didn't bother it), it dropped back into Open Firmware, and I had to repeat the reset and mac-boot commands. In the end, mine turned out to be a partition issue. I made my first partition 8 GB, not less then 8 GB... apparently it has to be LESS then 8 GB (so I repartitioned it to 7.5 GB and the problem went away). At least I think it was a parition issue... it went away after repartitioning, but I also had to reinstall Panther, so maybe it was really just an OS problem, I can't be sure which of the two actions fixed it. -chris <http://www.mythtech.net> -- The iMac List is sponsored by <http://lowendmac.com/> and...
