Dear All, (1) If USB mouse or USB keyboard is used under Windows environment, they can easily be detected. Then, if I use USB mouse and USB keyboard in DOS, then how can both of them be detected? Or, if I buy a new DIY PC with USB mouse and USB keyboard, then, how can I configurate my BIOS and setup my Windows OS (before any USB driver can be loaded)? Then, it seems that I also need (or borrow) standard keyboard .....??? ------------------- (2) Then, can USB be the futher peripheral interface? regards, William -- http://www.piclist.com#nomail Going offline?
