My post is here http://bbs.bios.net.cn/thread-75895-1-1.html, but it's in Chinese. download pdf and some moded insyde bios at http://oho77.ys168.com Another thought,here,i just tested,it works,http://forums.mydigitallife.net/threads/7551 mod without ezh2o,here,http://bbs.bios.net.cn/thread-86930-1-1.html,also in Chinese. Attention,please!!! I am sorry for some acer users,many of them can't activate,now I will explain. If your original bios can activate vista,then the moded bios can activate win7 when flashed with vendor-supplied insydeflash. If your original bios can't activate vista.When you use the unoffical insydeflash (such as insydeflash 3.52,to download at oho77.ys168.com)to flash the vendor-supplied bios(*.fd),slic 2.0 will appear and vista will be activated. That's to say,using the unoffical insydeflash to flash the moded bios,slic 2.1 will appear.But,you have to recover uuid and sn after doing this.
