Hi, here is my spec, Mac Pro 2009, Snow Leopard, Areca ARC-1680ix-16: Mac OS raid array & Scratch Disk raid array latest EFI firmware I just got a new raid controller, Highpoint Rocketraid eSATA for Mac. I would like to know is it possible to use a PC Bio for this card, so I can dual boot a windows raid array through this Highpoint card? I am having a trouble to follow the menu of Highpoint card, the OSX doesn't allow me to create a boot camp 1. Does the machine carry the firmware (EFI/ BIO) or the controller itself? 2. If I update the a PC bio on the Highpoint Rocketraid eSATA for Mac, is it going to affect my Areca controller since the Areca is using EFI firmware to boot OSX. Thank you!
