NAME

       pcelx - 3COM EtherLink III PCMCIA Ethernet Adapter

SYNOPSIS

       network@<socket>:pcelx<socket>

       The  pcelx  driver  supports  the  3COM EtherLink III PCMCIA PC Card as a standard Ethernet type of device conforming to the DLPI interface
       specification.  The driver supports the hot-plugging of the PC Card.

       The PPA (Physical Point of Attachment) is defined by the socket number the PC Card is inserted in. This means that for IP use, the PC  Card
       should  always  be  plugged  into  the same socket that the network interface was initially brought up on or else a network reconfiguration
       should be done to take down the old interface and bring up the new one.

       The 3C589, 3C589B, and 3C589C versions of the PC Card are supported on the  platform. The 3C589B and 3C589C  are  supported  on	the  SPARC
       platform.

PRECONFIGURE

	 o  For  IBM  ThinkPad	760E  series systems and systems using the TI PCI1130 PCI-to-CardBus chip (such as the Dell Latitude XPi CD) only:
	    Before bringing the system onto the network, put the PC Card into 8-bit mode by creating a file called /kernel/drv/pcelx.conf contain-
	    ing force-8bit=1;.

	 o  It is not possible to boot or install the Solaris software using a 3Com EtherLink III PC Card device.

	 o  If	the  3Com PC Card device is recognized, the pcelx driver is automatically loaded, ports and IRQs allocated, and special files cre-
	    ated (if they don't already exist). No manual configuration of the hardware is necessary or possible.

   Known Problems and Limitations
       Network services are automatically started when the system is booted.  These services are not started when a network interface is added	or
       shut down after the system has been brought up.

CONFIGURATION

       Configuration  procedures  include  initial  installation  and  configuration, identifying an unrecognized card and configuring two or more
       cards.

   Initial Installation and Configuration
       For initial installation and configuration, do the following steps:

       1.  Install the Solaris software.

       2.  Boot the system.

       3.  Insert the 3Com EtherLink III PC Card device.

   Identifying an Unrecognized Card
       If you insert a 3C589 card and it is not recognized (no special files created), use the prtconf command and attempt to identify	the  prob-
       lem:

       1.  Become root.

       2.  Run the prtconf -D command to see if your 3C589 card is recognized. A recognized device will appear in the prtconf output. For example:

	   # prtconf -D
	   .  .  .
	   pcic, instance #0 (driver name: pcic)
	   .  .  .
	      network, instance #0 (driver name: pcelx)

       3.  If pcelx does not appear in the prtconf output, there is a problem with the PC Card adapter configuration or with the hardware. You can
	   determine whether the problem is with the card or the adapter by attempting to use the card on another machine or by using  it  on  the
	   same machine using DOS.

   Configuring Two or More Cards
       Because the 3C589 card is not supported during Solaris installation, you must update network configuration files before it can be used as a
       network interface:

       1.  Create a /etc/hostname.pcelx# file (where # is a socket number) to specify the host name to be associated with this interface.

       2.  Add an IP address for the new host name to the /etc/inet/hosts file.

       3.  Ensure that the associated network is listed in /etc/inet/netmasks.

       4.  Ensure that the Name Service Switch /etc/nssswitch.conf configuration file includes the network and local services you need.

       5.  Reboot the system.

   Special Files
       Device naming in /dev follows standard LAN device naming with the exception that the PPA (physical point of attachment) unit number is  the
       socket  where the card resides, not the instance. For the pcelx driver, /dev/pcelx0 (or PPA 0 of /dev/pcelx) is the card in socket 0, while
       a card in socket 1 is /dev/pcelx1 (or PPA 1 of /dev/pcelx).

   Hot Plugging
       If you remove the 3C589 card, any information you send is discarded, and no error messages are given.

       When you reinsert the card in the same socket, the device operates normally.  The behavior is  similar  to  temporarily	disconnecting  the
       device from the network.
