What's New
This is a partial list of new features and systems included in OpenBSD 4.8. For a comprehensive list, see the changelog leading to 4.8.
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 4.8 on your machine:
OpenBSD/i386:
If you already have an OpenBSD 4.7 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:
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:
Note that most ports are available as packages through FTP. Updated packages for the 4.8 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 [email protected] is a good place to know.

- bgpd(8) control sockets are now specified in the config file. This removes the -s and -r arguments to bgpd.
- Extended the BGP MPLS VPN support to allow Layer-3 MPLS VPNs to be terminated on OpenBSD with the help of mpe(4), ldpd(8), and bgpd(8).
- bgpd(8) supports multiple FIBs and it is possible to assign them to RIBs for redistribution.
- bgpd now supports to use neighbor-as in AS filter statements and added two new filters -- max-as-seq and max-as-len -- to limit the length of a sequence of a single AS or the total length of an AS path.
- Added softreconfig support in bgpd for peers changing the RIB.
- Fixed multiprotocol MRT dumps and added 4-byte AS-Number support in bgpd(8).

- Generic network stack improvements:
- ifconfig(8) and route(8) get better Multiprotocol Label Switching support.
- traceroute(8) now supports extended ICMP headers which allows printing of MPLS labels.
- Support for RFC 4941 privacy extensions for stateless address autoconfiguration has been added to inet6(4) and can be enabled via ifconfig(8).

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 CD1:4.8/i386/floppy48.fs to a floppy and boot via the floppy drive.
Use CD1:4.8/i386/floppyB48.fs instead for greater SCSI controller support, or CD1:4.8/i386/floppyC48.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 CD1:4.8/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
- The 4.8 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 CD2:4.8/amd64/floppy48.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.
- 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 /4.8/macppc/bsd.rd
- 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 CD3:4.8/sparc64/floppy48.fs or CD3:4.8/sparc64/floppyB48.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 CD3:4.8/sparc64/miniroot48.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.
- Write FTP:4.8/alpha/floppy48.fs or FTP:4.8/alpha/floppyB48.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.
- 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.
- Boot over the network by following the instructions in INSTALL.hp300.
- Boot over the network by following the instructions in INSTALL.hppa or the hppa platform page.
- Write miniroot48.fs to the start of the CF or disk, and boot normally.
- Write miniroot48.fs to a USB stick and boot bsd.rd from it or boot bsd.rd via tftp. Refer to the instructions in INSTALL.loongson for more details.
- 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.
- 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.
- To install on an O2, burn cd48.iso on a CD-R, put it in the CD drive of your machine and select Install System Software from the System Maintenance menu. On other systems, or if your machine doesn't have a CD drive, you can setup a DHCP/tftp network server, and boot using "bootp()/bsd.rd.IP##" using the kernel matching your system type. Refer to the instructions in INSTALL.sgi for more details.
- After connecting a serial port, boot over the network via DHCP/tftp. Refer to the instructions in INSTALL.socppc for more details.
- Boot from one of the provided install ISO images, using one of the two commands listed below, depending on the version of your ROM.
- ok boot cdrom 4.8/sparc/bsd.rdor> b sd(0,6,0)4.8/sparc/bsd.rd
- ok boot floppyor> b fd()
- Boot over the network via mopbooting as described in INSTALL.vax.
- Using the Linux built-in graphical ipkg installer, install the openbsd48_arm.ipk package. Reboot, then run it. Read INSTALL.zaurus for a few important details.
- 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
- # mkdir -p /usr/src/sys# cd /usr/src# tar xvfz /tmp/sys.tar.gz
If you already have an OpenBSD 4.7 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# cd ports
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 [email protected]:/cvs update -Pd -rOPENBSD_4_8
Note that most ports are available as packages through FTP. Updated packages for the 4.8 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 [email protected] is a good place to know.
