Preparing Client Workstations
NOTE: If you specify an interrupt for the network board that is already being used by another
device, you can still install the network board but the network software will not run
successfully.
• Base I/O port
The base input/output port is a channel used by the network board to transfer
information to the CPU. Each hardware device included in your client
workstation must have a different base I/O port setting. For more information,
see the manufacturer’s documentation.
The following table shows a list of standard I/O ports and the devices that
commonly use them. If a workstation does not have any one of these devices, the
I/O port given in the table for that device might be available for other use.
