I'm putting together a workstation that primarily is going to be used for Windows development and I wanted to have as fast a disk subsystem as possible. It doesn't seem to be BootCamp drivers available for the card that Apple sells, so I found this card instead: http://www.areca.com.tw/products/pcietosas1680series.htm It has EFI firmware and is able to boot MacOSX from raid arrays. The only question is if it is able to boot stuff through Bios emulation. Vista x64 is the primary target here, and SP1 actually has EFI booting support, so it might be possible to use this. However when I tried to install Vista x64 with SP1 integrated on the MacBook Air I wasn't even able to boot installer DVD because of EFI incompatibilities. Anyone have any experiences with booting BootCamp on a MacPro with a raid card?
