Use the following instructions to build AFS modifications into the kernel on an IRIX system.

	1. Copy the kernel initialization file afs.sm to the local /var/sysgen/system directory, and the kernel master file afs to the local /var/sysgen/master.d directory.

	
<verbatim>
	# cp -p  bin/afs.sm  /var/sysgen/system
	
	# cp -p  bin/afs  /var/sysgen/master.d
</verbatim>
	

	2. Copy the appropriate AFS kernel library file to the local file /var/sysgen/boot/afs.a; the IPxx portion of the library file name must match the value previously returned by the uname -m command. Also choose the file appropriate to whether the machine's kernel supports NFS server functionality (NFS must be supported for the machine to act as an NFS/AFS Translator). Single- and multiprocessor machines use the same library file.

		If the machine's kernel supports NFS server functionality:

	
<verbatim>
	# cp -p	bin/libafs.IPxx.a	/var/sysgen/boot/afs.a	
</verbatim>

		If the machine's kernel does not support NFS server functionality:

	
<verbatim>
	# cp -p  bin/libafs.IPxx.nonfs.a  /var/sysgen/boot/afs.a
</verbatim>
	

	3. Issue the chkconfig command to deactivate the afsml configuration variable.

	
<verbatim>
	# /etc/chkconfig -f afsml off	
</verbatim>

		If the machine is to function as an NFS/AFS Translator and the kernel supports NFS server functionality, activate the afsxnfs variable.

	 
<verbatim>
	# /etc/chkconfig -f afsxnfs on
</verbatim>
	

	4. Copy the existing kernel file, /unix, to a safe location. Compile the new kernel, which is created in the file /unix.install. It overwrites the existing /unix file when the machine reboots in the next step.

	
<verbatim>
	# cp /unix /unix_noafs
	
	# autoconfig
</verbatim>
	

	5. Reboot the machine to start using the new kernel, and login again as the superuser root.

	
<verbatim>
	# cd /
			
	# shutdown -i6 -g0 -y
	
	login: root
	Password: root_password
</verbatim>
