Information Library for Solaris 2.6 (Intel Platform Edition)

PC Card Devices

PC Card devices can be inserted at any time during the boot process or after the Solaris environment is running since PC Card peripherals are hot-pluggable and configured automatically by the software.

Issue	What to Do
How to know if there are enough IRQs available to run a two-socket adapter.	Three IRQs must be available to use devices in both of the sockets. One IRQ is required for the adapter itself, and one is needed for each device inserted in a socket.

Allocating IRQs--Sample Procedure

Boot with the Configuration Assistant diskette 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.

If your system has a COM2 port but it is not being used, delete the port to leave the IRQ resource free for a PC Card.
1. Select the serial port device using IRQ 3, and choose Delete Device.
2. Choose Continue to return to the Device Tasks menu.
3. Save the configuration.

Boot the Solaris software.
