pod jakym OS to chces provozovat? s linuxem by to jet melo:
My machine has two serial ports, two times PS/2 (keyboard and mouse) and two times USB. So i could connect:
o two ps/2 keyboards (yes, one on the mouse port)
o two serial mice
o one usb keyboard
o one usb mouse

Make sure you have all this hardware and make sure it works. Test all mice under X, make sure the usb keyboard works (you should be able to type both on the ps/2 and the usb keyboard). The keyboard connected to the ps/2 mouse port will not work yet, but we'll fix that later.
