| | pcic - Intel i82365SL PC Card Interface Controller |
| |
The Intel i82365SL PC Card interface controller provides one or more PCMCIA PC card sockets. The pcic driver implements a PCMCIA bus nexus driver.
The driver provides basic support for the Intel 82365SL and compatible chips. The chips that have been tested are:
- Intel 82365SL
- Cirrus Logic PD6710/PD6720/PD6722
- Vadem VG365/VG465/VG468/VG469
- Toshiba PCIC and ToPIC
- Ricoh RF5C366
- Texas Instruments PCI1130/PCI1131/PCI1031
While most systems using one of the above chips will work, some systems will not be supported due to hardware designs options that may not be software detectable. Note that systems with CardBus interfaces are only supported in the non-legacy mode. Systems that only initialize
the bridge to legacy mode and do not configure the PCI memory will not be supported.
Direct access to the PCMCIA hardware is not supported. All device access must be through the Card Services interface of the DDI.

- Install your add-in PC Card adapter prior to the Solaris installation.
- Some systems have their built-in PC Card adapter disabled by default. Enable it prior to Solaris installation.
- Requirements for a system depend on the combination of devices to be used. A typical two-socket system needs at least 8 Kbytes of address space, 16 bytes of I/O space, and three free IRQs. Following are general guidelines:
| Address space | At least 8 Kbytes are required with 4 Kbytes per socket in the 640K-1MB range (not necessarily contiguous); if there are three sockets, at least 12 Kbytes are needed. |
| I/O space | At least 8 and preferably 16 bytes per socket. |
| IRQs | One per socket, plus an IRQ for the pcic device driver itself. |
|
| |
There is one driver configuration property defined in the pcic.conf file.
-
interrupt-priorities=11;
- This property must be defined and must not be modified from the default value.
Initial Installation and Configuration
| |
To perform initial installation and configuration, do the following steps:
- 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.
|
Adding PC Card Support to a Previously Installed System
| |
To add PC card support to a previously installed system, do the following:
- Become root.
- Do a reconfiguration reboot to reallocate resources:
- 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.
|
Allocating IRQs
| |
To allocate the IRQs, do the following:
- 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 an unused COM2 or parallel port, delete the device to free the IRQ resource for a PC Card. To do this, select the serial port device using IRQ 3 or the parallel port using IRQ 7, and choose Delete Device. Next, choose Continue to return to the Device Tasks menu, then
save the configuration.
- Boot the Solaris software.
