Patch Installation Instructions: 

1.	Boot the machine single user, clean the disks, and start a csh(1).

		> b -s
	or
		ok boot -s

		# fsck -f -p
		# exec csh
		<host># source /.cshrc
		<host># source /.login

2.	Load this patch in a location that has disk space.  This
	example assumes that /var is a separate partition and that
	the patch is delivered on tape.

	<host># mount /var
	<host># cd /var
	<host># mkdir -p patches/<PATCH_NUMBER_HERE>
	<host># cd patches/<PATCH_NUMBER_HERE>
	<host># tar xvf /dev/rst0

3.	Install the patch and check the "log" for errors.
	<host># ./install_patch |& tee log
	<host># vi log

3a.     This patch contains changes to the machine's kernel. In order
	for the changes to take effect, the kernel must be reconfigured.

	To reconfigure the kernel, follow the procedure in the README
	file, located in the /export/exec/kvm/<arch>/sys/<arch>/conf
	directory for each architecture.

4.	Reboot the machine.
	<host># cd /
	<host># umount -at cfs
	<host># sync; sync; sync; reboot
