What's New

This is a partial list of new features and systems included in OpenBSD 4.0. For a comprehensive list, see the changelog leading to 4.0.

How to install

Following this are the instructions which you would have on a piece of paper if you had purchased a CDROM set instead of doing an alternate form of install. The instructions for doing an FTP (or other style of) install are very similar; the CDROM instructions are left intact so that you can see how much easier it would have been if you had purchased a CDROM instead.

Please refer to the following files on the three CDROMs or FTP mirror for extensive details on how to install OpenBSD 4.0 on your machine:

Quick installer information for people familiar with OpenBSD, and the use of the "disklabel -E" command. If you are at all confused when installing OpenBSD, read the relevant INSTALL.* file as listed above!

OpenBSD/i386:

Play with your BIOS options to enable booting from a CD. The OpenBSD/i386 release is on CD1. If your BIOS does not support booting from CD, you will need to create a boot floppy to install from. To create a boot floppy write CD1:4.0/i386/floppy40.fs to a floppy and boot via the floppy drive.

Use CD1:4.0/i386/floppyB40.fs instead for greater SCSI controller support, or CD1:4.0/i386/floppyC40.fs for better laptop support.

If you can't boot from a CD or a floppy disk, you can install across the network using PXE as described in the included INSTALL.i386 document.

If you are planning on dual booting OpenBSD with another OS, you will need to read INSTALL.i386.

To make a boot floppy under MS-DOS, use the "rawrite" utility located at CD1:4.0/tools/rawrite.exe. To make the boot floppy under a Unix OS, use the dd(1) utility. The following is an example usage of dd(1), where the device could be "floppy", "rfd0c", or "rfd0a". 

# dd if=<file> of=/dev/<device> bs=32k

Make sure you use properly formatted perfect floppies with NO BAD BLOCKS or your install will most likely fail. For more information on creating a boot floppy and installing OpenBSD/i386 please refer to this page.

OpenBSD/amd64:

The 4.0 release of OpenBSD/amd64 is located on CD2. Boot from the CD to begin the install - you may need to adjust your BIOS options first. If you can't boot from the CD, you can create a boot floppy to install from. To do this, write CD2:4.0/amd64/floppy40.fs to a floppy, then boot from the floppy drive.

If you can't boot from a CD or a floppy disk, you can install across the network using PXE as described in the included INSTALL.amd64 document.

If you are planning to dual boot OpenBSD with another OS, you will need to read INSTALL.amd64.

OpenBSD/macppc:

Put CD2 in your CDROM drive and poweron your machine while holding down the C key until the display turns on and shows OpenBSD/macppc boot.

Alternatively, at the Open Firmware prompt, enter boot cd:,ofwboot /4.0/macppc/bsd.rd

OpenBSD/sparc:

The 4.0 release of OpenBSD/sparc is located on CD3. To boot off of this CD you can use one of the two commands listed below, depending on the version of your ROM. 

ok boot cdrom 4.0/sparc/bsd.rd
or
> b sd(0,6,0)4.0/sparc/bsd.rd

If your SPARC system does not have a CD drive, you can alternatively boot from floppy. To do so you need to write CD3:4.0/sparc/floppy40.fs to a floppy. For more information see this page. To boot from the floppy use one of the two commands listed below, depending on the version of your ROM. 

ok boot floppy
or
> b fd()

Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install will most likely fail.

If your SPARC system doesn't have a floppy drive nor a CD drive, you can either setup a bootable tape, or install via network, as told in the INSTALL.sparc file.

OpenBSD/sparc64:

Put CD3 in your CDROM drive and type boot cdrom.

If this doesn't work, or if you don't have a CDROM drive, you can write CD3:4.0/sparc64/floppy40.fs or CD3:4.0/sparc64/floppyB40.fs (depending on your machine) to a floppy and boot it with boot floppy. Refer to INSTALL.sparc64 for details.

Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install will most likely fail.

You can also write CD3:4.0/sparc64/miniroot40.fs to the swap partition on the disk and boot with boot disk:b.

If nothing works, you can boot over the network as described in INSTALL.sparc64.

OpenBSD/alpha:

Write 4.0/alpha/floppy40.fs or 4.0/alpha/floppyB40.fs (depending on your machine) to a diskette and enter boot dva0. Refer to INSTALL.alpha for more details.

Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install will most likely fail.

OpenBSD/armish:

After connecting a serial port, Thecus can boot directly from the network either tftp or http. Configure the network using fconfig, reset, then load bsd.rd, see INSTALL.armish for specific details. IOData HDL-G can only boot from an EXT-2 partition. Boot into linux and copy 'boot' and bsd.rd into the first partition on wd0 (hda1) then load and run bsd.rd, preserving the wd0i (hda1) ext2fs partition. More details are available in INSTALL.armish.

OpenBSD/cats:

After updating the firmware to at least ABLE 1.95 if necessary, boot 4.0/cats/bsd.rd from an ABLE-supported device (such as a CD-ROM or an existing FFS or EXT2FS partition).

OpenBSD/hp300:

Boot over the network by following the instructions in INSTALL.hp300.

OpenBSD/hppa:

Boot over the network by following the instructions in INSTALL.hppa or the hppa platform page.

OpenBSD/luna88k:

Copy bsd.rd to a Mach or UniOS partition, and boot it from the PROM. Alternatively, you can create a bootable tape and boot from it. Refer to the instructions in INSTALL.luna88k for more details.

OpenBSD/mac68k:

Boot MacOS as normal and extract the Macside "BSD/Mac68k Booter" utility from 4.0/mac68k/utils onto your hard disk. Configure the "BSD/Mac68k Booter" with the location of your bsd.rd kernel and boot into the installer. Refer to the instructions in INSTALL.mac68k for more details.

OpenBSD/mvme68k:

You can create a bootable installation tape or boot over the network.
The network boot requires a MVME68K BUG version that supports the NIOT and NBO debugger commands. Follow the instructions in INSTALL.mvme68k for more details.

OpenBSD/mvme88k:

You can create a bootable installation tape or boot over the network.
The network boot requires a MVME88K BUG version that supports the NIOT and NBO debugger commands. Follow the instructions in INSTALL.mvme88k for more details.

OpenBSD/sgi:

Burn cd40.iso on a CD-R, put it in the CD drive of your machine and select Install System Software from the System Maintenance menu.

If your machine doesn't have a CD drive, you can setup a DHCP/tftp network server, and boot using "bootp()/bsd.rd". Refer to the instructions in INSTALL.sgi for more details.

OpenBSD/vax:

Boot over the network via mopbooting as described in INSTALL.vax.

OpenBSD/zaurus:

Using the Linux built-in graphical ipkg installer, install the openbsd40_arm.ipk package. Reboot, then run it. Read INSTALL.zaurus for a few important details.

Notes about the source code

src.tar.gz contains a source archive starting at /usr/src. This file contains everything you need except for the kernel sources, which are in a separate archive. To extract: 

# mkdir -p /usr/src
# cd /usr/src
# tar xvfz /tmp/src.tar.gz

sys.tar.gz contains a source archive starting at /usr/src/sys. This file contains all the kernel sources you need to rebuild kernels. To extract: 

# mkdir -p /usr/src/sys
# cd /usr/src
# tar xvfz /tmp/sys.tar.gz

Both of these trees are a regular CVS checkout. Using these trees it is possible to get a head-start on using the anoncvs servers as described here. Using these files results in a much faster initial CVS update than you could expect from a fresh checkout of the full OpenBSD source tree.

How to upgrade

If you already have an OpenBSD 3.9 system, and do not want to reinstall, upgrade instructions and advice can be found in the Upgrade Guide.

Ports Tree

A ports tree archive is also provided. To extract: 

# cd /usr
# tar xvfz /tmp/ports.tar.gz

The ports/ subdirectory is a checkout of the OpenBSD ports tree. Go read the ports page if you know nothing about ports at this point. This text is not a manual of how to use ports. Rather, it is a set of notes meant to kickstart the user on the OpenBSD ports system.

The ports/ directory represents a CVS (see the manpage for cvs(1) if you aren't familiar with CVS) checkout of our ports. As with our complete source tree, our ports tree is available via anoncvs. So, in order to keep current with it, you must make the ports/ tree available on a read-write medium and update the tree with a command like: 

# cd [portsdir]/; cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_4_0

[Of course, you must replace the local directory and server name here with the location of your ports collection and a nearby anoncvs server.]

Note that most ports are available as packages on our mirrors. Updated packages for the 4.0 release will be made available if problems arise.

If you're interested in seeing a port added, would like to help out, or just would like to know more, the mailing list ports@openbsd.org is a good place to know.
