help~!! 我唔小心 delete 左sound max .....

You can go to www.ibm.com.hk and search the driver. I have found one for you. Try this one:
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-58558

Because your PC is IBM, all the drivers of IBM PC could be download from the website of IBM. (www.ibm.com).
Try to search the IBM website yourself and you will get much more idea on it. As my company use the IBM PC, I always download the related drivers from www.ibm.com.hk

我相信您指delete左個 driver, if so...
you can go to the following website to download the driver back... Since you did not mention what version and I think this could be the possible match

www.techspot.com/drivers/driver/file/uop/view/3311/

Note: this is for version ADI SoundMax AC97 Integrated Digital Audio Driver v 5.12.01.3620 D
