Hi I have a 1.25 DP MDD running 10.3.9. Im trying to run Protools 6.4 with a Digi 001 interface and PCI card. When nothing is plugged in the computer runs fine and it is seeing the card in its slot. after shut down, I plug in the interface to the PCI and then, the computer wont boot up AT ALL...no power up ( I have tried all 4 slots, 2 cables, 2 interfaces, and 2 PCI cards) I have an older G4 500 MHZ, everything works fine in that computer just slower. I reloaded Protools into the MDD to try to reload any drivers, but no success. what am I missing??? -------------- next part -------------- An HTML attachment was scrubbed...
