Adding and configuring parallel ports

To configure parallel ports on your system:

1. Shut down the system using the System Shutdown Manager or the shutdown(ADM) command.

2. Install the card that holds the parallel port(s) (if it is not already present), and configure your hardware according to the manufacturer's instructions. If your system includes a configuration disk or BIOS setup program, use it as instructed. If your system is configured with switch settings on the main system board (motherboard), define the new ports by setting the proper switches (refer to your hardware manuals for the settings).

3. Boot the system, and enter system maintenance mode by entering the root password.

4. Start the Hardware/Kernel Manager and select Parallel Port from the devices listed, or run mkdev parallel.

   The system determines what parallel ports (if any) are configured and displays the results (this may take several seconds).

5. You can select Configure an ISA parallel port or Modify configuration of PCI parallel ports.

   To add ISA parallel ports:

   1. Select the type of card you are installing.

   2. Select the base I/O address it uses from the menu or specify a non-standard address.

   3. Unless you are installing on an MCA machine, enter the interrupt vector.

   To modify the configuration of PCI parallel ports:

   1. Enter the total number of PCI parallel ports -- on all of the cards in your system -- that you want to use. (See ``Modifying PCI parallel port configurations'' for more information.)

6. Relink the kernel as described in ``Relinking the kernel''.

7. If you have no further changes to make, use the System Shutdown Manager or the shutdown(ADM) command to shut down the system and reboot.
