Prerequisites
The following are required to use this device driver:
• QNX level 4.XX operating system
• An ISA- or PCI-based machine
Note: This Reference Card assumes that you are
familiar with the QNX 4.XX operating system.
How to Use the On-Line Help
This device driver provides on-line help that shows how
to initialize the device driver. To start the help system,
enter the following:

Installing RocketPort Systems
Use the following procedure to install and configure
RocketPort series systems with the
driver.
If necessary, set the I/O address
DIP switch on any ISA cards.
Install the cards in the system.
Install the device driver.
Initialize the card.
Note: Refer to the Hardware Reference Card for
hardware installation information or use the
Readme file that came with the driver.
If you are installing a RocketPort ISA in an EISA-bus
computer, you may need the EISA configuration files.
The EISA configuration files are available on the
Comtrol ftp site or the diskette that contains the
Diagnostics for the RocketPort series.

Loading the Driver
Before loading the driver, make sure that you have
installed the RocketPort ISA or PCI cards. If you are
installing an ISA card, it may be necessary to change
the
I/O address (default is 180) setting. Use the
Reference Card
installation procedures.
To load the driver, issue the following command line
from either the command prompt or from the
config/sysinit
sample command lines.
If you are installing RocketPort PCI cards, they are
detected before any of the RocketPort ISA cards and you
do not need to specify I/O addresses or IRQs for
RocketPort PCI cards. The system determines the order
of the PCI cards.
Note: If you type '
