Most of this is gone, into pmax/install.  Just keep a mention that
backups are important.

-Installing NetBSD/pmax using the sysinst tool and an image of a full
-bootable root filesystem is now a relatively painless process.  The
-diskimage is avaiable via (either a diskimage, dd'able to a raw disk
-or tarfile to for NFS .
-.Pp
-From most convenient to least convenient, the installation methods
-are:
-.Bl -enum
-.It
-Booting as a diskless workstation via Ethernet,
-followed by initialization of the local disk and
-installing onto the local disk over NFS.
-.It
-Copying a bootable diskimage onto the beginning of a disk
-and installing onto that disk 
-.It
-installation using a helper machine to set up a bootable
-NetBSD/pmax  root filesystem, and moving the disk
-to the target.
-.It
-Installation from Ultrix or other OSes by putting a copy
-of the diskimage into the existing swap partition and a copy
-of the NetBSD kernel into your Ultrix root filesystem.
-.El
-.Pp
-Before you start, you must choose an installation method.  If you have
-an Ethernet connection to an NFS server that can provide even ~30M for
-a diskless-root filesystem, then installation via the net is best.
-Next best, if your DECstation is already running Ultrix and has two
-disk drives (or one, if you live dangerously), is to copy a diskimage
-onto one drive.  Finally, you can install by using a second machine as
-a helper to prepare a bootable NetBSD/pmax disk.
-.Pp
-If your target is going to run diskless, then installation proceeds as
-for method 1.
-.Pp
-This release of NetBSD/pmax uses the new sysinst installation utility.
-You should examine the guide on the NetBSD/pmax web site, which has
-more complete and more up-to-date instructions for sysinst.  The
-following is a brief synopsis which has been successfully followed by
-both first-time NetBSD/pmax installers and to upgrade existing
-gsystems.
-.Pp
-You should familiarize yourself with the console PROM environment
-and the hardware configuration. The PROMs on the older Decstation
-2100 and 3100 use one syntax. The PROMs on the TurboChannel machines
-use a completely different syntax.  Be sure you know how to print
-the configuration of your machine, and how to boot from disk or
-network, as appropriate.
-.Pp
-On the 2100/3100, that's
-.Bd -literal -offset indent
-boot -f rz(0,N,0)netbsd (boot from rzN)
-boot -f tftp()          (boot diskless via TFTP)
-boot -f tftp()          (boot via MOP from an Ultrix server)
-.Ed
-On the 5000/200, the equivalent is
-.Bd -literal -offset indent
-boot 5/rzN/netbsd
-boot 6/tftp
-boot 6/mop
-.Ed
-and on other  5000 series machines,
-.Bd -literal -offset indent
-boot 3/rzN/netbsd
-boot 3/tftp
-boot 3/mop
-.Ed
-You will also need to know the total size (in sectors) and the
-approximate geometry of the disks you are installing onto, so that you
-can label your disks for the BSD fast filesystem (FFS).  For most SCSI
-drives (including all SCSI-2 drives), the kernel will correctly detect
-the disk geometry. The sysinst tool will suggest these as the default.
-.Pp
-If you're installing NetBSD/pmax for the first time it's a very good
-idea to pre-plan partition sizes for the disks on which you're
-installing NetBSD.  Changing the size of partitions after you've
-installed is difficult.  If you do not have a spare bootable disk, it
-may be simpler to re-install NetBSD again from scratch.
-.Pp
-If you install by copying a disk image, and you want to change the size
-of the root partition from the default 32Mbytes, you will need a second
-`scratch' disk. You should copy the diskimage onto the `scratch' disk,
-boot the scratch disk, and use it to create a tailored root filesystem.
-This is because you cannot change the size of an active partition (i.e.,
-the root filesysem you booted). The standard trick to get around this is
-to put a cut-down miniroot into the swap partition, boot the miniroot,
-and use that system to change the root filesystem size.  DECstation
-PROMs don't reliably support booting off partitions other than the 'a'
-partition, which is why you need two disks to tailor the root filesystem
-size.
-.Pp
-Assuming a classic partition scheme with separate root (`/') and /usr
-filesystems, a comfortable size for the NetBSD root filesystem
-partition is about 32M.  A good initial size for the swap partition is
-twice the amount of physical memory in your machine (though, unlike
-Ultrix, there are no restrictions on the size of the swap partition
-that would render part of your memory unusable).  The default swap
-size is 64Mbytes, which is adequate for doing a full system build.  A
-full binary installation, with X11R6.3, takes about 150MB in `/usr'.
+First and foremost, before beginning the installation process,
+.Em make sure you have a reliable backup
+of any data on your hard disk that you wish to keep. Mistakes in
+partitioning your hard disk may lead to data loss.
