What I'd like to do is put a FireWire card in my FreeBSD NAS, and then export a ZVOL on a specific FireWire port in target mode so that it can be used as a raw block device on a Mac Mini as its root filesystem. This will have the advantage of being faster than the internal 2.5" IDE HDD and also having the ability to take snapshots and backups from the NAS system. I was curious to know if this was technically possible, and if so if anyone had done this and had success? Is there any limitation on this if so? Are both 400 and 800 ports bidirectional in this manner? I have 400-400 and 400-800 cables, so I could use either on the target (the Mac Mini is 400 only). Before I purchase any hardware, I want to be certain this would work out. Thanks all, Roger
