	  Say Y to include support for the EtherNEC network adapter for the

	  ROM port. The driver works by polling instead of interrupts, so it

	  is quite slow.



	  This driver also suppports the ethernet part of the NetUSBee ROM

	  port combined Ethernet/USB adapter.



	  To compile the actual ethernet driver, choose Y or M in for the NE2000

	  option in the network device section; the module will be called ne.
