Consult the Configuration Assistant for address space, I/O space, and IRQs already used by system devices.
Insert the PC Card adapter.
Install the Solaris software.
Reboot the system.
Do a reconfiguration reboot to reallocate resources:
# touch /reconfigure # reboot
Insert the PC Card adapter and turn on the machine.
Boot the system so that the PC Card device driver begins running with the new resources allocated.
Boot with the Configuration Assistant so you can review the resource usage.
Select View/Edit Devices from the Device Tasks menu, and review the list of devices to see how many IRQs are being used.
There are 16 IRQs, from 0-15. Several IRQs are already assigned. For example, IRQ 3 is reserved for the second serial port, COM2, and IRQ 7 is reserved for the parallel port.
If your system has a COM2 port or a parallel port that is not being used, delete the device to free the IRQ resource for a PC Card.
Boot the Solaris software.
