I've been running my Mac Pro 1,1 (upgraded to 2,1 , X5365, HD4870, 32gb, 10.9 with the tiamo efi, etc) booting from a HighPoint RocketRaid 4322. My most recent replacement for the 4322 which I just received Wednesday is the newer 4522. I thought this was a good thing until I found out that the efi firmware for the 4522 was only for efi64 and not efi32 like the 4322. I was wondering if it was possible to boot from the 4522 using Chameleon or Clover since they provide efi64 compatibility. I can view my RAID array from within Windows 8.1 which is booting from my internal drive, so I know it's working properly. I figured I'd pick some brans here before making many fruitless attempts at making this work and getting frustrated.
