Close AHCI, no roadblocks on installation road

AHCI is a joint research and development interface standard for several companies, including Intel, to get higher signal transmission speed and improve HDD efficiency by about 30%. Typically, only Sataⅱ hard drives and newer (such as Intel ich7r) motherboard bridge chips work together to support this feature. While the ThinkPad SL500 uses the Intel PM45 chipset with the 160G Sataⅱ hard drive, the factory AHCI mode is turned on by default, and the earlier WinXP system disk generally does not have "AHCI" drive, which leads to "blue screen event".
