Installing Lava Multi Serial PCI cards under QNX4.25 1. With the power turned off, insert the Lava Multi Serial card into any free PCI slot in your computer. Refer to the computer and card manuals for details on how to install PCI cards. 2. Turn on your computer, boot into the QNX 4.25 operating system and log in as "root". 3. Run the "show_pci" utility with the "-v" option. 4. Look through sections starting with the string "Vendor ID = 1407h" in the output of the "show_pci" utility. 5. Write down the base addresses and interrupt lines used by installed ports. Note that for some Lava devices there are a few addresses in a single line "Base Address = ..." of the "show_pci" utility. All serial ports installed on a single PCI card share the same interrupt line. The number of any given interrupt line can be found in strings beginning "Interrupt Line = ...". 6. Slay the "Dev.ser" driver. Simply type "slay Dev32.ser" in the shell prompt (or "slay Dev16.ser" if you are using a 16 bit driver). 7. Start the serial driver again with the appropriate command line options. Check out the usage message of Dev.ser or refer to the operating system documentation for the command line options of the serial driver. 8. If everything works as expected, edit the file /etc/config/sysinit.<node> to add command line options for "Dev.ser". Everything will be in place after rebooting your system. Note 1: The master device manager "Dev" has the maximum number of devices set to 64 by default. By installing additional Lava serial ports, you can easily run over this maximum. In this case you need to pass the appropriate option to "Dev" manager (for example: "Dev -n100"). Note 2: The serial device driver in QNX 4.25 has an internal limitation on the maximum number of serviced devices. This limit is 64 devices per driver instance. If you are going to install more than 64 serial ports into your system you need to run several instances of "Dev.ser" (You need to use the "-Nname" option of the "Dev.ser" driver) or contact QNX technical support for a custom driver. Note 3: After moving a Lava Multi Serial PCI card into another PCI slot of your computer, you likely have to repeat the steps described above because the BIOS could assign other addresses and interrupt lines for your serial ports. Example: Installing 12 additional serial ports into computer 1. Two Lava Multi Serial boards were installed into PCI slots. Slot 1: "Octopus-550" [eight-port serial PCI board] and slot 2: "Quattro-PCI" [four-port serial PCI board]. 2. Login: root # 3. # show_pci | more ...
