Suggest booting from cd-rom as the first choice. Document that cd54.iso is

now bootable on all supported platforms (although it will still need manual
operation on IP22), but that install54.iso is currently still not bootable
on IP27/IP35.

 There are several ways to install OpenBSD onto a disk. The easiest way
-in terms of preliminary setup is to use the OpenBSD ramdisk kernel that
-can be booted via BOOTP. The normal way is to use the bootable CD-ROM
-mini image.
+in terms of preliminary setup is to use the bootable CD-ROM mini image.
+Alternatively, the OpenBSD ramdisk kernel can be booted from the network,
+using a bootp/tftp server.
+
+Booting from CD-ROM installation media:
+
+	NOTE: Only cd${:--:}OSrev.iso may be booted on IP27 and IP35 class systems,
+	due to PROM limitations. install${:--:}OSrev.iso will not boot, but may be
+	used to the sets without requiring network access.
+
+  From the System Maintenance Menu, select '2' (or click on the
+  appropriate icon if in graphics console) to Install System Software.
+
+  If necessary, select the proper CD-ROM drive, and press enter to
+  confirm your choice.  Insert the installation CD-ROM (if you did not
+  do so already) and press enter to boot the system.
+
+  If the boot is successful, you will get a loader version message,
+  executable sizes, and then the kernel copyright and device probe
+  messages. Boot failure modes are typically a lot of CD-ROM drive
+  activity, but no messages or complaints about magic numbers,
+  checksums or formats.
+
+  If the system does not complain about being able to read the CD-ROM,
+  but of not being able to load a particular file, you can nevertheless
+  boot manually. This is the case on IP22 systems.
+
+  To boot manually from the CD-ROM, select ``Enter Command Monitor''
+  at the menu, and invoke the bootloader and ramdisk image manually.
+  For example, on an IP22 system, automatic boot may fail with:
+
+dnl IP22
+	Cannot load scsi(1)cdrom(4)partition(8)sashARCS.
+	Text start 0x10000, size 0xa120 doesn't fit in a FreeMemory area.
+	Cannot load scsi(1)cdrom(4)partition(8)sashARCS -- not enough space.
+
+  or:
+
+dnl IP20, changed from scsi(0) to scsi(1) for consistency
+	Cannot load scsi(1)cdrom(4)partition(8)sashARCS.
+	Error 15 while loading scsi(1)cdrom(4)partition(8)sashARCS
+
+  The name of the CD-ROM drive is then ``scsi(1)cdrom(4)'', and the manual
+  boot command will be:
+
+	>> scsi(1)cdrom(4)partition(8)bootecoff
+	   scsi(1)cdrom(4)partition(0)/bsd.rd.IP22
+
+  Note that this is a single commandline, the two paths should be separated
+  with spaces.
