I just bought a used G4 tower with OsX. I installed a pci card for my Digi 001 audio interface (to be used with ProTools) and started up the machine to find a grey screen that reads "DEFAULT CATCH!, code=700 at %SSR0: ff80ca54 %SSR1: 00003030". It then asks me if i would like to shut down or continue booting. when i boot it goes to a screen with a folder in the middle and stops. The computer works fine without the card in. Has anybody heard of this problim or know how to fix it? Any help would be great.
