SCO OpenServer
Troubleshooting
Before you call Comtrol technical support, please check the following:
• Check to make sure all cables are connected properly.
• Check the signals between your peripherals and the RocketPort
interface box to verify that they match (if applicable). See the
RocketPort Hardware Reference Card for port pinouts.
• If using an ISA-bus RocketPort/RocketModem, check to make sure
the DIP switch I/O address settings on the board match the I/O
address you used when installing the device driver software.
• Make sure the controller board is seated firmly in the bus slot.
• Make sure the expansion slot screw is in place.
• Reinstall the board and device driver software, selecting a different
I/O address range for the controller. For possible I/O address
conflicts, see the System I/O Address tables.
If the above steps fail to resolve the problem, follow these steps:
1. Shut down your system.
2. Place the RocketPort Diagnostics diskette in your primary drive.
3. Power-up your system, and allow it to boot from the diagnostic
diskette.
4. Follow the on-screen instructions to run the diagnostic program.
If this fails to resolve the problem, see the Introduction section of this
guide for information about contacting Comtrol technical support.
PCI-Bus I/O Conflicts
On occasion, a system will report a PCI-bus board as NOT FOUND
due to an I/O conflict during boot-up.
To resolve this problem, follow these steps:
1. Run the diagnostics to determine the I/O address of the PCI board.
(This is set automatically by the system.) Note this address.
2. Boot into SCO.
3. Edit the file /etc/conf/sdevice.d/rckt. Change the PCI board address
shown to the actual address you noted in step 1.
4. Use the /etc/conf/cf.d/link_unix command to relink the kernel. Or,
using the GUI interface, go to the System Administration folder,
open the Hardware Kernel Manager, and click the Relink Kernel
button. Select Y for the answers to all prompts.
5. Reboot the system.
