Will MOTU 24I/O work with Logic Pro 9?

I am new to Logic Pro having converted from Sonar 7. I have a MOTU 24io and need to connect it to my iMac. I have been racking my brain trying to find help and all I can see is people say no. My former computer had the required PCI 424 card for firewire 400. I am not convinced. Is there a way to make it work?
