I've just upgraded my G3 beige desktop 233 with CPU accelerator card
type G4 - 1Ghz sonnet

since I can't star cubase VST5.1
crash on startup - error message 10 11 3
and miscellaneous other messages
can't find cubase ressources.....

under OS8.6 with korg 1212IO

somebody can help me

You should start with all extension off (hold down shift key when you start up.)
Remove all Cubase & Korg extensions, then restart.
If it boots up normally, start putting in the removed extensions one by one.

I suspect the Korg driver may be the culprit.

If all else fail move up to 9.1 -> 9.2.1->9.2.2 (you can get the OS9.1 disc real cheap now 9.2.1 &9.2.2 are free from apple.)

ok azusa
i'm going to try this process but today I can't cause my disk is crashed

otherwise, I've already try to install OS 9.2.2 but it was a disaster because my OMS did not response to my hardware, too
and no more results for cubase.

then I've decide to reinstall OS 8.6 and no result anyhow.

This problem is occured when the datas of my old crashed dish(again!!! ) were bringed to my new harddrive (the new one with a factory default....)
and since this day, nothing run now.
before this day, everything started. Then now I'm looking for a solution but I know some CPU upgrade card are not compatible with cubase.

(looked on cubase web site) sonnet is not culprit now but this card is very recent (july 2003) and I'm afraid of an incompatility with CUBASE and SONNET
