Hi, To install Debian , for the first time, I used the CD from the book "Debian GNU/Linux Bible" When I assign my mouse protocol PS/2 and selected the /dev/psaux with Emulate3Button my systems hangs. I have to reboot. If I use Microsoft and /dev/ttyS01 it works. When I boot my system, I see that my port PS/2 is recognize. Does anyone have an idea why I cn't use PS/2? Thanks. Wayne
