+There are three basic ways a system can be bootstrapped corresponding to the
+first three files.
+You may want to read the section on bootstrapping the HP300
+since many of the steps are similar.
+A spare, formatted SCSI disk is also useful.
+.NH 4
+Procedure A: copy root filesystem to disk
+.PP
+This procedure is similar to the HP300.
+If you have an extra disk, the easiest approach is to use \fIdd\fP\|(1)
+under ULTRIX to copy the root filesystem image to the beginning
+of the spare disk.
+The root filesystem image includes a disklabel and bootblock along with the
+root filesystem.
+An example command to copy the image to the beginning of a disk is:
+.DS
+.ft CW
+dd if=root.image of=/dev/rz1c bs=20b
+.DE
+The actual special file syntax will vary depending on unit numbers and
+the version of ULTRIX that is running.
+This system is now ready to boot.
+You will probably want to change the disk label
+to create reasonable partitions for your machine (see section 4.2).
+You can then proceed to section 2.5 to install the rest of the system.
+.NH 4
+Procedure B: bootstrap from tape
+.PP
+If you have only a single machine with a single disk,
+you need to use the more difficult approach of booting a
+kernel and mini-root from tape or the network, and using it to restore
+the root filesystem.
+.PP
+First, you will need to create a boot tape. This can be done using
+\fIdd\fP as in the following example.
+.DS
+.ft CW
+dd if=vmunix.tape of=/dev/nrmt0 bs=1b
+dd if=root.dump of=/dev/nrmt0 bs=20b
+.DE
+The actual special file syntax for the tape drive will vary depending on
+unit numbers, tape device and the version of ULTRIX that is running.
+.PP
+The first file on the boot tape contains a boot header, kernel, and
+mini-root file system that the PROM can copy into memory.
+Installing from tape has only been tested
+on a 3100 and a 5000/200 using a TK50 tape drive. Here are two example
+PROM commands to boot from tape.
+.DS
+.ft CW
+DEC 3100: boot \-f tz(0,5,0) m # 5 is the SCSI id of the TK50
+DEC 5000: boot 5/tz6 m # 6 is the SCSI id of the TK50
+.DE
+The `m' argument tells the kernel to look for a root filesystem in memory.
+Next you should proceed to section 2.4.3 to build a disk-based root filesystem.
+.NH 4
+Procedure C: bootstrap over the network
+.PP
+You will need a host machine that is running the \fIbootp\fP server
+with the vmunix.net file installed in the default directory defined by the
+configuration file for \fIbootp\fP.
+Here are two example PROM commands to boot across the net:
