+Before you start you should familiarize yourself with the boot PROM
+of your machine. The older Decstation 2100 and 3100 cannot select
+a kernel from the command line. You need to set the bootpath
+environment variable to point to the disk and kernel you intend to boot.
+
+You should also examine the guide on the OpenBSD/pmax web site, which
+will hopefully soon have more complete and more up-to-date
+instructions than are given in the install document.
+
+If you're installing OpenBSD/pmax for the first time it's a very good idea
+to look at the partition sizes of disk you intend installing OpenBSD on.
+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
+OpenBSD again from scratch.
+
+But if you don't have a second disk or plan to do an installation via
+netbooting you don't have any choice about the partition sizes (at
+least not for the root and the swap partitions) because they are set
+in the simpleroot image to to 32M for root and 64M for swap. About the
+rest of your disk you can still decide yourself.
+
+Asumming a classic partition scheme with root (`/') and /usr filesystems,
+a comfortable size for the OpenBSD 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). A full binary installation, without X11 or other additional
+software, takes about 130MB in `/usr'.
