 this document in hand it shouldn't be too much trouble.
 
 There are several ways to install OpenBSD onto a disk. The easiest way
-in terms of preliminary setup is to use the OpenBSD simpleroot that can
-be booted off your local disk. Alternatively, if your Decstation is
-hooked up in a network you can find a server and arrange for a
-diskless setup which is a convenient way to install on a machine whose
-disk does not currently hold a usable operating system (see the
-section `Installing using a diskless setup' below).
+in terms of preliminary setup is to use the OpenBSD ramdisk kernel that
+can be booted off your local MSDOS disk or from the CD-ROM.
 
 
-Installing using the OpenBSD simpleroot.
+Installing using the OpenBSD ramdisk kernel.
 
-The miniroot is a self-contained OpenBSD filesystem holding a complete
-OpenBSD/pmax rootfilesystem plus all utilities necessary to install
-OpenBSD on a local disk. It is distributed as a plain file designed to
-be transferred to a raw disk partition from which it can be booted
-using the appropriate PROM command.
+The ramdisk kernel is a self-contained OpenBSD filesystem including all
+utilities necessary to install OpenBSD on a local disk, embedded in a
+GENERIC kernel image. It is distributed as a plain ECOFF executable file
+designed to be loaded into the system by the ARC firmaware.
 
-Loading the simpleroot onto your raw partition is simple. On OpenBSD
-as well as SunOS you use a command like:
+Loading the ramdisk kernel into your system is done with the appropriate
+BIOS Run command on Your system. Usually this is done by typing in the
+following string at the "Run a program" prompt:
 
-	# dd if=simpleroot21.fs of=/dev/rsd0c bs=20b conv=sync
+	scsi()disk()rdisk()partition(1)\bsd.rd
 
-Especially on OpenBSD/pmax you'll have to use /dev/rrz0c or something
-like that instead of /dev/rsd0c.
+to boot from an existing MSDOS FAT partition to which the ramdisk kernel
+have been copied. Or from the CD-ROM:
 
-Keep in mind that this will overwrite the contents of that disk!
+	CD:\2.1\arc\bsd.rd
 
-After transferring the simpleroot to disk, bring the system down by:
+Exact input to describe the device path varies. Consult your ARC-Bios manual
+for more information about the particular system.
 
-	# halt
+This will cause the ramdisk kernel to be booted. After the initial probe
+messages you'll asked to choose a shell with sh as default. Simply type
+[Return] here and you are in single user mode.
 
-Then boot the miniroot by typing the appropriate command at the PROM:
 
-	>> boot rz(0,0,0)/bsd		# for Decstation 2100/3100
+Start the installation script:
 
-or
+	# install
 
-	>> boot 5/rz0a/bsd		# for Decstation 5000's
 
-If you've loaded the simpleroot onto some other disk than `rz0' adapt
-the boot specifier accordingly.
-
-This will cause the kernel contained in the simpleroot to be booted.
-After the initial probe messages you'll asked to choose a shell with
-sh as default. Simply type Return here and you are in single user
-mode.

-Installing using a diskless setup.
-
-First, you must setup a diskless client configuration on a server. If
-you are using a OpenBSD system as the boot-server, have a look at the
-diskless(8) manual page for guidelines on how to proceed with this.
-If the server runs another operating system, you'll have to consult
-documentation that came with it (on SunOS systems, add_client(8) is a
-good start).
-
-XXX more to come here
-
-As noted above in the section `Preparing your System for OpenBSD Installation',
-you have several options when choosing a location to store the installation
-filesets. However, the easiest way is to put the *.tar.gz files you want
-to install into the root directory for your client on the server.
-
-Next, unpack `base.tar.gz' and `etc.tar.gz' on the server in the root 
-directory for your machine. If you elect to use a separately NFS-mounted
-filesystem for `/usr' with your diskless setup, make sure the "./usr" base
-files in base.tar.gz end up in the correct location. One way to do this is
-to temporarily use a loopback mount on the server, re-routing <root>/usr to
-your server's exported OpenBSD "/usr" directory. Also put the kernel and the
-install/upgrade scripts into the root directory.
-
-A few configuration files need to be edited:
-
-	<root>/etc/hosts
-		Add the IP addresses of both server and client.
-
-	<root>/etc/myname
-		This files contains the client's hostname; use the same
-		name as in <root>/etc/hosts.
-
-	<root>/etc/fstab
-		Enter the entries for the remotely mounted filesystems.
-		For example:
-			server:/export/root/client       /     nfs  rw 0 0
-			server:/export/exec/sun4.OpenBSD /usr  nfs  rw 0 0
-
-Now you must populate the the `/dev' directory for your client. If you server
-runs SunOS 4.x, you can simply change your working directory to `<root>/dev'
-and run the MAKEDEV script: `sh MAKEDEV all'.
-
-On SunOS 5.x systems, MAKEDEV can also be used, but there'll be error
-messages about unknown user and groups. These errors are inconsequential
-for the purpose of installing OpenBSD. However, you may want to correct them
-if you plan to the diskless setup regularly. In that case, you may re-run
-MAKEDEV on your OpenBSD machine once it has booted.
-

-
-This will boot the OpenBSD kernel in single-user mode.
-
-If you use a diskless setup with a separately NFS-mounted /usr filesystem,
-mount /usr by hand now:
-
-OpenBSD# mount /usr
-
-XXX more to come here
-
-Here follows an example of what you'll see while in the dislabel editor.
-Do not touch any of the parameters except for the `label: ' entry and
-the actual partition size information at the bottom (the lines starting
-with `a:', `b:', ...).
-
-The size and offset fields are given in sector units. Partitions on
-which you intend to have a mountable filesystem, should be given
-fstype `4.2BSD'. Remember, the `c' partition should describe the whole
-disk. The `(Cyl. x - y)' info that appears after the hash (`#')
-character is treated as a comment and need not be filled in when
-altering partitions.
-
-Special note: the line containing `8 partitions:' is best left alone,
-even if you define less then eight partitions. If this line displays
-a different number and the program complains about it (after you leave
-the editor), then try setting it to `8 partitions:'.

+The script will do most of the work of transferring the system from the
 tar files onto your disk. You will frequently be asked for confirmation
 before the script proceeds with each phase of the installation process.
 Occasionally, you'll have to provide a piece of information such as the
 name of the disk you want to install on or IP addresses and domain names
-you want to assign. If your system has more than one disk, you may want
-to look at the output of the dmesg(8) command to see how your disks

+you want to assign.
 
 The installation script goes through the following phases:
 
 	- determination of the disk to install OpenBSD on
-	- checking of the partition information on the disk
+	- checking of the MBR partition information on the disk
+	- checking of the OpenBSD partition information on the disk
 	- creating and mounting the OpenBSD filesystems
 	- setup of IP configuration
 	- extraction of the distribution tar files
-	- installation of boot programs
+	- installation of kernel and the bootable kernel
+
+The installation program will guide you through the installation. There is
+one area of complexity that you should be very careful about and that is
+how to install the requiered MBR (Msdos Boot Record) and MSDOS FAT partition.
+
+OpenBSD will coexist with other operating systems with help from the MSDOS
+partition table. Because the ARC Bios only knows how to boot from a FAT
+formatted disk there must always exist a small or big (depending on your
+needs) MSDOS FAT partition on the disk. Install will initialize the install
+target disk with a proper MBR and an empty 5Mb MSDOS partition it that is
+desired. Or it will keep the curent MBR and partitioning. In the later case
+you will need to fill in the MBR with a usable OpenBSD partition.
+
+
+Now try a reboot (enter the command "reboot" at the prompt). This will take
+you back to the ARC Bios. You will now need to set up a boot selection to
+boot OpenBSD. How to do this varies from system to system and should be
+described in your systems manual. The process to set up the parameters is
+almost exactly the same as for Win/NT apart from the name of the OSLOADER
+which should be set to 'bsd'. You may also set the OSLOADOPTIONS parameter
+to any of the following characters:
 
+	n = Ask for root device Name.	N = Don't as for root device Name.
+	a = Autoboot to Multiuser mode.	A = Boot to single user mode.
 
-Now try a reboot.  (If needed, swap your scsi id's first).  Initially
-I'd suggest you "boot" (Decstation 2100/3100) or "boot/rz0a/bsd", then
-try multiuser after that. if you boot single-user the OpenBSD
-incantation to make the root filesystem writable is
+So to boot the system to multiuser mode set:
 
-    OpenBSD# mount -u /dev/sd0a /
+	OSLOADOPTIONS=Na

 Congratulations, you have successfully installed OpenBSD 2.1.  When you
 reboot into OpenBSD, you should log in as "root" at the login prompt.
