I'm so confused. if there is any one get the slow result like mine? What is wrong with the first linePCIIDE-BAD) I had reinstalled my mbp lion and reinstall win7 twice. it still couldnt fix it In my os x lion system, I used novabench, the result is:1220 very very fast. I had installed win 7 x64 ultimate. I have had found many people say that to change the BIOS into AHCI mode it would makes a huge difference in turns of performance. I also tried many ways and still couldnt figured out how to get into my mbp2011 version into win7's BIOS or how to CHANGE it into AHCI mode. Anybody would help me here. thank you peace!
