NAME

     pcic - Intel i82365SL PC Card Interface Controller

DESCRIPTION

     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:

        o  Intel 82365SL

        o  Cirrus Logic PD6710/PD6720/PD6722

        o  Vadem VG365/VG465/VG468/VG469

        o  Toshiba PCIC and ToPIC

        o  Ricoh RF5C366

        o  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  sys-
     tems  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.

PRECONFIGURATION

        o  Install your add-in  PC  Card  adapter  prior  to  the
           Solaris installation.

        o  Some systems have their built-in PC Card adapter  dis-
           abled by default. Enable it prior to Solaris installa-
           tion.

        o  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 neces-|
          |              |  sarily contiguous); if there are  three  sock-|
          |              |  ets, 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  dev-|
          |              |  ice driver itself.                            |
          |______________|________________________________________________|

CONFIGURATION

     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:

     1. Consult the Configuration Assistant  for  address  space,
        I/O space, and IRQs already used by system devices.

     2. Insert the PC Card adapter.

     3. Install the Solaris software.

     4. 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:

     1. Become root.

     2. Do a reconfiguration reboot to reallocate resources:

     # touch /reconfigure

     # reboot

     3. Insert the PC Card adapter and turn on the machine.

     4. 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:

     1. Boot with the Configuration Assistant so you  can  review
        the resource usage.

     2. 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.)

     3. 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.

     4. Boot the Solaris software.
