Hi Antonio, I just did a complete system rebuild this weekend, and I now have an S900 running Jaguar with a very similar setup to yours:
Supermac S900 Sonnet Crescendo G3 400 w/1 meg 2:1 cache 528 megs FPM non-EDO ram, interleaved Radeon 7000 Mac edition ACARD AHARD 66 IDE controller IBM Deskstar 80 gig IDE drive (OS X) Quantum Fireball 2 gig SCSI drive (OS 9) Macally Firewire card Belkin USB card One key difference in our setups is the IDE card. I'm not sure about how the Sonnet works, but the ACARD masquerades its IDE buses as SCSI buses, which from what I understand, helps a lot with getting Mac OS X working. I also have the entire 80 gig drive dedicated to one OS X partition. If you don't mind spending another $50, try getting the ACARD... chances are that the ATA 66 vs ATA 133 isn't going to make a whole lot of difference in a system with such a slow PCI bus and system bus, and maybe it would just work a little better. Which slot do you have the IDE card in? If you haven't already, try putting it in the top slot. I have mine in the top slot, with the Radeon in the second slot, then a USB card and a Firewire card in the two slots after that. Have you tried finding any new firmware to update the Sonnet IDE card with? The Radeon 7000 also had a ROM update in the last couple of months, have you tried installing that in OS 9? I did experience a LONG black screen when I first installed Jaguar with the Radeon - but not 16 hours long. I have a feeling it has something to do with the point at which the Radeon drivers are loaded during startup... then again, maybe not. How about swapping out the ram entirely for new, matched ram? Also, what type of ram do you have? Though EDO and FPM dimms are both supposed to work, FPM (non-EDO) DIMMs are recommended. These are fairly generic recommendations, but even though you already have OS 9 working, chance are OS X will require a little more TLC. Here's to hoping you get it working!
