Tech / Why would a PCI card not work in a similar Mac?

« on: October 15, 2010, 08:20:52 AM »

Your line of thinking was certainly an interesting trouble-shooting angle! I just tried starting up my old G4 450 from the MDD-ified, super-updated OS 9.2.2, via Firewire, and this worked, including using LOGIC (the audio software) with the STUDI/O card. No problem. Which means it's not the software, nor the MDD-specific new Extension versions of the "special" OS 9.2.2. As long as I'm using the old hardware, everything is fine. So at least it seems clear that the problem is hardware related. The audio card works inside the old computer. However it appears to be incompatible inside the newer MDD Dual 1.25. Maybe something to do with the much faster CPU, the busses, or the way PCI slots are addressed.

Well, that's what I get for upgrading my computer! ;-)
Everything's been moved over to the new (well, NEW for ME, anyway...) computer, in the hopes of running everything from this one machine, using OS X and having the option to still boot from Classic as well, on the last, fastest Mac that still allows that. But things being the way they are, I now have to make room for two computers, complete with two monitors and two keyboards/mice. At least until I can drum up a whole new audio card, as well. Which is not really in the cards right now (as it were...).

Thanks again for all you guys's brainstorming assistance!

Hey Paddy and gunug,

Thanks for your thoughts on my quandary. And yes, those other posts in different forums were by me, too. (Thanks for those links, gunug! You never know, it could've been something to shed extra light.) It seems as if the upshot of it all is: my "smartly" upgrading to a "new-est" computer of the same type as my tested-and-proven G4 probably wasn't smart enough. I may have to incur yet more expenses to move this thing forward.

In any case, thanks for the dialog!

Additional bit: The STUDI/O card is not supported in OS X, and Sonorus has closed its doors. So there's no help forthcoming from that direction. But in OS 9, everything should be good to go. Could a somewhat newer, faster computer like the Dual 1.25 really have that much of a detrimental impact on a PCI card?

Why would an Audio Interface PCI card work in one Mac G4, but not in a newer, similar computer?

My Sonorus STUDI/O audio interface card has been working great in my G4 450 (AGP), through various MacOS versions, now in OS 9.2.2, using LOGIC recording software.

Putting the card in a Power Mac G4 Dual 1.25 Ghz (MDD Mirror Drive Door), the card is recognized by Apple System Profiler, but Logic abruptly quits without explanation as soon as it starts up and tries to acknowledge and integrate the card.

Throwing away Logic’s Preferences will let me successfully start up LOGIC, and choosing the basic MacAV as the audio engine will work just fine (so it’s not the application itself that’s broken). But if I specify the STUDI/O, as soon as I relaunch LOGIC to activate that choice, the program just quits without explanation again.

Same system (OS 9.2.2) as in the G4 450 (except that the Mirror Drive’s OS 9 was a slightly newer, machine-specific build).
No special drivers needed, as LOGIC supports the card directly.
I tried all available PCI slots, with no difference.

So why would a PCI card suddenly not work at all in a newer, but comparable Mac? Any ideas?

Thanks,
Peter
