The keyboard does not respond.
Try attaching an external keyboard to the PS/2 connector 
on the computer’s rear.  If it works, contact your dealer or 
an authorized service center as the internal keyboard cable 
may be loose.
The serial mouse does not work.
Check the following:
Make sure that the serial cable is plugged securely into 
the serial port.
During POST, press F2 to access the Setup Utility.  Go 
to the Advanced screen and verify that the serial port is 
enabled.  See “Startup Configuration” on page 87 for 
details.
I prefer using an external keyboard and mouse, but both 
have PS/2 connectors and there is only one PS/2 port on the 
computer.
To connect two PS/2-type devices to the computer, you 
need to use a PS/2 Y-bridge connector.  See “PS/2 Y-Bridge 
Cable” on page 52 for details.
The printer does not work.
Check the following:
Make sure that the printer is connected to a power 
outlet and it is turned on.
Make sure the printer cable is connected securely to the 
computer’s parallel port and the corresponding port on 
the printer.
During POST, press F2 to access the Setup Utility.  Go 
to the Advanced screen and verify that the parallel port 
is enabled.  See “Startup Configuration” on page 87 for 
details.
