Since computer is new, should be XP?! Chinese input already "build in", u may need the XP CDs. CHECK OLD POSTINGS on Sino, as I am not using it right now and cannot give u the DETAILED instructions, start with something REGIONS. Good luck!
鼠标点击左下角的“start”-->Settings-->Control Panel-->Date,time,language...-->Regional ang Language Options然后会弹出一个框来,上面有三个Tab选项,先选中间的Language Tab选项,将里面的Install files for Ease Asia Language打上钩,然后选最右边的Advanced Tab选项,里面的下拉框选Chinese (PRC),然后鼠标点OK,系统就会自动帮你装好中文支持了。
