SE(4)			  OpenBSD Programmer's Manual			 SE(4)

NAME
     se - SiS 190/191 10/100/Gigabit Ethernet device

SYNOPSIS
     se* at pci?
     rlphy* at mii?

DESCRIPTION
     The se driver provides support for the SiS190 Fast Ethernet controller
     integrated into the SiS965L and SiS966L southbridges, and the SiS191
     Gigabit controller integrated into the SiS965 and SiS966 southbridges.

     Both SiS 190 and SiS 191 embed an Ethernet MAC with external PHY.	They
     use a bus master DMA and a scatter/gather descriptor scheme and include a
     64-bit multicast hash filter.

     The se driver supports the following media types:

     autoselect	  Enable autoselection of the media type and options.  The
		  user can manually override the autoselected mode by adding
		  media options to the hostname.if(5) file.

     10baseT	  Set 10Mbps operation.	 The mediaopt option can also be used
		  to select either full-duplex or half-duplex modes.

     100baseTX	  Set 100Mbps (Fast Ethernet) operation.  The mediaopt option
		  can also be used to select either full-duplex or half-duplex
		  modes.

     1000baseSX	  Set 1000Mbps (Gigabit Ethernet) on fiber operation.  Only
		  full-duplex mode is supported at this speed.

     1000baseT	  Set 1000Mbps (Gigabit Ethernet) on copper operation.

     The se driver supports the following media options:

     full-duplex  Force full duplex operation.

     half-duplex  Force half duplex operation.

     For more information on configuring this device, see ifconfig(8).

DIAGNOSTICS
     seN: EEPROM read timeout  The driver could not read the controller's MAC
     address from its EEPROM.

     seN: invalid EEPROM signature  The driver could not find the expected
     EEPROM signature and could not read the controller's MAC address.

     seN: Could not find PCI-ISA bridge	 The driver could not read the
     controller's MAC address from the CMOS memory connected to the PCI-ISA
     bridge.

     seN: PHY read timeout  The driver could not read data from the PHY.

     seN: PHY write timeout  The driver could not write data to the PHY.

     seN: watchdog timeout  The device has stopped responding to the network,
     or there is a problem with the network connection (cable).

HISTORY
     The se driver first appeared in OpenBSD 4.8.

AUTHORS
     The se driver was adapted by Alexander Pohoyda
     <alexander.pohoyda@gmx.net> from the sis(4) driver written by Bill Paul
     <wpaul@ee.columbia.edu>, and ported to OpenBSD by Christopher Zimmermann
     <madroach@zakweb.de>.  SiS 191 support was added by Nikolay Denev
     <ndenev@gmail.com>.
