Problem - New 2.2MPB won't boot w/ Ext. FW drive?

[benulous]

I just got a new 2.2MPB to replace my old 867 Titanium. When I plug my older external firewire drive i've been using with my titanium, and boot up the new MBP, it just sticks at a blank screen. No Apple Logo, no boot time-thingy..just a blank screen. NOW, here is where it gets kinda weird, I have a Firewire audio interface [m-audio 810], when I plug THAT directly to the MBP and THEN the chain the ext. drive off that, it boots fine and I can see files on the drive.

I tried my friend's ext fw drive as well, and after a couple reboots, it finally saw HIS drive - but only after a couple reboots?

Does anyone have any ideas of what's going on - or had a similar experience?

Stupid question, but are these FW drives bootable? Do they have a PPC installation of OS X on them? That will stop the MBP cold. It will try and fail to boot off the PPC system.

I don't believe there are bootable files on there...but i've had the drive for a long time...maybe i have some files from an older system that i didn't realize was on there....I'll check in a few...only thing is that it works fine on my other laptop?

But your other laptop is a PPC, right? That's the point. The Macbook Pro isn't.
