Resolving Resource Conflicts

If you encounter problems while installing your client adapter on a computer running a Windows
operating system, you may need to specify a different interrupt request (IRQ) or I/O range for the
adapter.
The default IRQ for the client adapter is IRQ 10, which may not work for all systems. Follow the steps
for your specific operating system to obtain an available IRQ.
During installation the adapter's driver installation script scans for an unused I/O range. The installation
can fail if the I/O range found by the driver installation script is occupied by another device but not
reported by Windows. An I/O range might not be reported if a device is physically present in the system
but not enabled under Windows. Follow the steps for your specific operating system to obtain an
available I/O range.
