So im using a Power Mac 2009 Model. I've Boot camped Windows 7 32bit onto a partition on my hard drive. However while using this side of the hard drive I noted an anomaly. of the 16 GB of Ram installed on the computer only 2 GB of it are not "Reserved for Hardware". After some study I found that this is a fairly common issue with windows 7 32bit. The fix they suggest is upgrade the system BIOS (the equivalent of firmware as I understand it) alright fair enough. But i'm running all this off a mac. How do I do this? without messing up either side of the partition?
