Dear Gurus, Ivan Drucker asked if anyone had experience running firewire with 9.1. I've a 2400/240 9.1 and use a CBFW2 to pull MP3's off an IMac DV in target mode. I can only install the card after start up, then connect to the DV and must eject both before shutdown. I've found that the necessary Apple & CBFW2 extensions tend to disable themselves so that I've made a lean firewire set on Conflict Catcher and after I start up I check both the extensions folder and conflict catcher to be sure they're loaded. Then I insert card and hold breath. Donald McCaig
