Helpful in some ways, but not completely. I used Bootcamp to boot vista, which does support the 3132 card, and it could not see the raid configuration on the Venus raid enclosure I have, which means there is a difference in the way the raid is put together. The Venus box does not have a firewire option, and a Snow Leopard Mac Pro will not boot off a Leopard DVD, at least not on my machine. It just spits the Leopard install DVD out. I was somewhat hopeful that this idea might work.
My backups are on the RAID system, silly me for using a redundant error-correcting system for my backups. I also don’t have another Mac Pro sitting around.
So, I am going to have to wait for Silicon Image to get around to creating a RAID driver for the 3132 card that actually works on Snow Leopard.
