An IRQ conflict with an Adaptec 1522 SCSI controller could cause this
problem, or it could just be that we have three NE2000 devices at the
same I/O port.  In the latter case, you probably want to build a
kernel for your machine.  Right now the best way to build a kernel is
to use a union mount:

	mkdir /u1/build
	mount_union -b /usr/src /u1/build
	cd /u1/build/sys/arch/i386/conf
	cp ATHENAADP MYKERNELNAME
	<edit MYKERNELNAME, remove the devices you don't want>
	config MYKERNELNAME
	cd ../compile/MYKERNELNAME
	make depend
	make
	mv /netbsd /onetbsd
	cp netbsd /netbsd
	shutdown -r now
