Has anyone been able to use one of the extra SATA ports to boot into windows? I have 5 HDs in the mac pro, 4 for OSX (set up as 2 Raid 0 drives) and a HD for XP. OSX sees all the drives and can access them (even a HD connected to either one of the extra SATA ports). Booting in windows is only possible when i have the XP HD in one of the 4 standard HD bays. If it set the XP HD to run from one of the extra ports, it won't boot, the MacPro will see it when pressing option and display it as a Boot drive along with my OSX boot drive, but after selecting the XP HD it won't boot. When I boot into XP using one of the standard bays, XP also will not see any drives connected on one of the extra SATA ports. I installed XP using one of the standard HD bays without any other HDs attached? wondering if this is the issue? tried to get XP to look for new hardware but no luck.
