How do I setup a network interface


For the condor interface do the following:

1. Make sure you have the condor product installed.  If you have it installed
you will have the following files.

For NH4000 series:

	/usr/src/uts/machine/M88K/lib_cnd
	/usr/src/uts/machine/M88K-RT/lib_cnd
	/usr/src/uts/machine/hcxif/if_cnd.h

For NH4000 series:

	/usr/src/uts/machine/NH5000/lib_cnd
	/usr/src/uts/machine/NH5000-RT/lib_cnd
	/usr/src/uts/machine/hcxif/if_cnd.h


2. In the config file make sure the cndintr line is uncommented.

	...
	driver  drXIw   cdev 54 vector drXIw_intr
	driver  eg              vector egintr
	driver  cnd             vector cndintr  <---- condor interrupt handler
	driver  gs      cdev 57 vector vgintr
	....


3. Also, in the config file make sure the condor controller and device lines
are uncommented and modified.

	...
	# controller    cnd0    at vba? csr 0xff5000    vector cndintr
	# device        cn0     at cnd0 drive 0
	# device        cn1     at cnd0 drive 1
	....

To use a condor board in the primary VME bus the lines would look like this.

	controller    cnd0    at vba0 csr 0xff5000    vector cndintr
	device        cn0     at cnd0 drive 0
	device        cn1     at cnd0 drive 1

To use a condor board in the secondary VME bus the lines would look like this.

	controller    cnd0    at vba1 csr 0xbfff5000    vector cndintr
	device        cn0     at cnd0 drive 0
	device        cn1     at cnd0 drive 1


4. In /etc/rc uncomment and modify the ifconfig lines for the condor devices.

	...
		## These are ports of HVMEbus Condor multiport ethernet controllers
			/usr/sbin/ifconfig cn0 down
			/usr/sbin/ifconfig cn1 down
			# /usr/sbin/ifconfig cn2 down
			# /usr/sbin/ifconfig cn3 down
	...
		## These are ports of HVMEbus Condor multiport ethernet controllers
			/usr/sbin/ifconfig cn0 192.168.36.101 up -trailers netmask 255.255.255.0
			/usr/sbin/ifconfig cn1 192.168.34.101 up -trailers netmask 255.255.255.0
			# /usr/sbin/ifconfig cn2 $hostname up -trailers
			# /usr/sbin/ifconfig cn3 $hostname up -trailers
	....


5. Build the appropriate device files in /dev.

	# cd /dev
	# ./MAKEDEV cn0
	# ./MAKEDEV cn1


6. Rebuild and reinstall the new kernel.
