so I finally finished with all my installs, including bluetooth 2.1 (easy as hell). I just have one final issue and this is reagarding, the bios. I had hackintoshed my mini after boxing day (lesss than a week before 1.6.2) which meant that I had to down grade my bios and unfortunally I'm running A04 and I'm just wondering how to upgrade, if it's exactly the same way as downgrading or do I have to do it differently, or will it screw up my configuration? And finally did anyone witness a performance increase??
