     xe -- Xircom PCMCIA Ethernet device driver

SYNOPSIS    [Toc]    [Back]

     device xe

DESCRIPTION    [Toc]    [Back]

     The xe driver supports PCMCIA Ethernet adapters based on Xircom CE2- and
     CE3-class hardware.  This includes devices made by Xircom along with various
 OEM manufacturers.  The following cards are supported:

	    +o	Xircom CreditCard Ethernet (PS-CE2-10)
	    +o	Xircom CreditCard Ethernet + Modem 28 (PS-CEM-28)
	    +o	Xircom CreditCard Ethernet + Modem 33 (CEM33)
	    +o	Xircom CreditCard 10/100 (CE3, CE3B)
	    +o	Xircom CreditCard Ethernet 10/100 + Modem 56 (CEM56)
	    +o	Xircom RealPort Ethernet 10 (RE10)
	    +o	Xircom RealPort Ethernet 10/100 (RE100)
	    +o	Xircom RealPort Ethernet 10/100 + Modem 56 (REM56, REM56G)
	    +o	Accton Fast EtherCard-16 (EN2226)
	    +o	Compaq Netelligent 10/100 PC Card (CPQ-10/100)
	    +o	Intel EtherExpress Pro/100 PC Card Mobile Adapter 16 (Pro/100
		M16A)
     Other similar devices using the same hardware may also be supported.

     Please note that the xe driver only supports PCMCIA cards and their Ethernet
 functions.  xe does not support the on-board modem device located
     on some version of the Ethernet/modem combo cards.  In particular, Xircom
     RealPort2 cards are not supported by this driver.

     The xe driver supports the following media types:

     autoselect 	   Enable autoselection of media type and options.

     10Base2/BNC	   Select 10Mbps operation on a BNC coaxial connector.

     10BaseT/UTP	   Select 10Mbps operation on a RJ-45 connector.

     100BaseTX		   Select 100Mbps operation.

     Note that 100BaseTX operation is not available on CE2-class cards, while
     the 10Base2/BNC mode is only available on CE2-class cards.  Full-duplex
     operation is currently not supported.  For more information on configuring
 network interface devices, see ifconfig(8).

DIAGNOSTICS    [Toc]    [Back]

     xe%d: Cannot allocate ioport
     xe%d: Cannot allocate irq	A fatal initialization error occurred while
     attempting to allocate system resources for the card.

     xe%d: Unable to fix your %s combo card  A fatal initialization error
     occurred while attempting to attach an Ethernet/modem combo card.

     xe%d: watchdog timeout: resetting card  The card failed to generate an
     interrupt acknowledging a transmitted packet.  May indicate a PCMCIA configuration
 problem.

     xe%d: no carrier  The card has lost all contact with the network; this
     usually indicates a cable problem.
