Hardware Installation
PS/2 Mouse and PS/2 Key board Ports
Connect a PS/2 mouse to the green 6-pin mini DIN connector. The
system will automatically assign IRQ 12 to the PS/2 mouse if one is
connected.
Connect a PS/2 keyboard to the purple 6-pin mini DIN connector.
If you want to connect a standard AT size (large DIN) connector, you
must use an adapter.
Universal Serial Bus Ports
You can connect two USB devices or USB hubs to the USB ports.
The USB ports provide a hardware interface for low-speed
peripherals such as the keyboard, mouse, joystick, scanner, printer
and telephony devices, and also support MPEG-1 and MPEG-2
digital video. The USB ports have a maximum bandwidth of 480
Mbits/sec (equivalent to 60 Mbytes/sec), and up to 127devices can
be attached. Fast devices can use the full bandwidth, while
lower-speed ones can transfer data using a 60 Mbytes/sec
sub-channel.
