-There is no previous release of NetBSD/hp300 to upgrade.
+It is possible to easily upgrade your existing NetBSD/hp300 system
+using the upgrade program in the miniroot.  If you wish to upgrade
+your system by this method, simply select the `upgrade' option once
+the miniroot has booted.  The upgrade program with then guide you
+through the procedure.  The upgrade program will:
+
+	* Enable the network based on your system's current
+	  network configuration.
+
+	* Mount your existing filesystems.
+
+	* Extract binary sets from the media of your choice.
+
+	* Fixup your system's existing /etc/fstab, changing the
+	  occurrences of `ufs' to `ffs' and let you edit the
+	  resulting file.
+
+	* Make new device nodes in your root filesystem.
+
+	* Copy a new kernel onto your root partition.
+	  NOTE: the existing kernel WILL NOT be backed up; doing
+	  so would be pointless, since a NetBSD 1.0 kernel will
+	  not run NetBSD 1.1 executables.
+
+	* Install a new boot block.
+
+	* Check your filesystems for integrity.
+
+While using the miniroot's upgrade program is the preferred method
+of upgrading your system, it is possible to upgrade your system
+manually.  To do this, follow the following procedure:
+
+	* Place _at least_ the `base' binary set in a filesystem
+	  accessible to the target machine.  A local filesystem
+	  is preferred, since there may be incompatibilities
+	  between the NetBSD 1.1 kernel and older route(8)
+	  binaries.
+
+	* Back up your pre-existing kernel and copy the 1.1
+	  kernel into your root partition.
+
+	* Reboot with the 1.1 kernel into single-user mode.
+
+	* Check all filesystems:
+
+		/sbin/fsck -p
+
+	* Mount all local filesystems:
+
+		/sbin/mount -a -t nonfs
+
+	* If you keep /usr or /usr/share on an NFS server, you
+	  will want to mount those filesystems as well.  To do
+	  this, you will need to enable the network:
+
+		sh /etc/netstart
+
+	  NOTE: the route(8) commands may fail due to potential
+	  incompatibilities between route(8) and the NetBSD 1.1
+	  kernel.  Once you have enabled the network, mount the
+	  NFS filesystems.  If you use amd(8), you may or may not
+	  have to mount these filesystems manually.  Your mileage
+	  may vary.
+
+	* Make sure you are in the root filesystem and extract
+	  the `base' binary set:
+
+		cd /
+		tar --unlink -zxvpf /path/to/base11.tar.gz
+
+	  NOTE: the `--unlink' option is _very_ important!
+
+	* Install a new boot block:
+
+		cd /usr/mdec
+		disklabel -B <root disk, e.g. sd0>
+
+	* Sync the filesystems:
+
+		sync
+
+	* At this point you may extract any other binary sets
+	  you may have placed on local filesystems, or you may
+	  wish to extract additional sets at a later time.
+	  To extract these sets, use the following commands:
+
+		cd /
+		tar --unlink -zxvpf <path to set>
+
+NOTE: you SHOULD NOT extract the `etc' set if upgrading.  Instead, you
+should extract that set into another area and carefully merge the changes
+by hand.
