Installing OpenBSD is a relatively complex process, but if you have this document in hand and are careful to read and remember the information which is presented to you by the install program, it shouldn't be too much trouble. Before you begin, you should know the geometry of your hard disk, i.e. the sector size (note that sector sizes other than 512 bytes are not currently supported), the number of sectors per track, the number of tracks per cylinder (also known as the number of heads), and the number of cylinders on the disk. The OpenBSD kernel will try to discover these parameters on its own, and if it can it will print them at boot time. If possible, you should use the parameters it prints. (You might not be able to because you're sharing your disk with another operating system, or because your disk is old enough that the kernel can't figure out its geometry.) You should now be ready to install OpenBSD. The following is a walk-through of the steps you will take while getting OpenBSD installed on your hard disk. If any question has a default answer, it will be displayed in brackets ("[]") after the question. If you wish to stop the installation, you may hit Control-C at any time, but if you do, you'll have to begin the installation process again from scratch. At this time the system can be installed from the supplied CD boot image or by network loading the bootloader. Once the bootloader is installed on the local hard drive, the system can boot from it. Although currently OpenBSD cannot share the same drive as Mac OS due to partitioning issues, systems that support more than one physical drive can dual boot using Open Firmware commands. (Refer to "OpenBSD OSREV Release Contents" above for information on how to access and boot from Open Firmware) You will then be presented with the OpenBSD kernel boot messages. You will want to read them, to determine your disk's name and geometry. Its name will be something like "sd0" and the geometry will be printed on a line that begins with its name. As mentioned above, you will need your disk's geometry when creating OpenBSD's partitions. You will also need to know the name, to tell the install tools what disk to install on. If you cannot read the messages as they scroll by, do not worry -- you can get at this information later inside the install program. While booting, you will probably see several warnings. You should be warned that no swap space is present, and that init(8) cannot find /etc/rc. Do not be alarmed, these are completely normal. When you reach the prompt asking you for a shell name, just hit return. You will be presented with a welcome message and a prompt. At this time you should enter the command "install" to start the installation process. You will be asked which terminal type to use, vt100 will work almost acceptably, however no terminal type quite works correctly) The install program will then tell you which disks of that type it can install on, and ask you which it should use. The name of the disk is typically "wd0" for IDE drives. Reply with the name of your disk. Next you will have to edit or create a disklabel for the disk OpenBSD is being installed on. If there are any existing partitions defined (for any operating system), and a disk label is not found, you will first be given an opportunity to run fdisk and create an OpenBSD partition. If fdisk is being invoked on your behalf, it will start by displaying the current partitions defined and then allow you to modify this information, add new partitions and change which partition to boot from by default. If you make a mistake, you will be allowed to repeat this procedure as necessary to correct this. Note that you should make OpenBSD be the active partition at least until the install has been completed. Next the disk label which defines the layout of the OpenBSD file systems must be set up. The installation script will invoke an editor allowing you to do this. Note that partition 'c' inside this disk label should ALWAYS reflect the entire disk, including any non-OpenBSD portions. The root file system should be in partition 'a', and swap is usually in partition 'b'. If you have DOS or Linux partitions defined on the disk, these will usually show up as partition 'h', 'i' and so on. It is recommended that you create separate partitions for /usr and /var, and if you have room for it, also for /home. Currently OpenBSD will not share a disk with any other operating system care should be taken not to overwrite any data on other disks in the system and that no data is on the disk to be used for OpenBSD/MACHINE. Note that all OpenBSD partitions in the disk label must have an offset that makes it start within the OpenBSD part of the disk, and a size that keeps it inside of that portion of the disk. This is within the bounds of the 'c' partition. The swap partition (usually 'b') should have a type of "swap", all other native OpenBSD partitions should have a type of "4.2BSD". Block and fragment sizes are usually 8192 and 1024 bytes, but can also be 4096 and 512 or even 16384 and 2048 bytes. The install program will now label your disk and ask which file systems should be created on which partitions. It will auto- matically select the 'a' partition to be the root file system. Next it will ask for which disk and partition you want a file system created on. This will be the same as the disk name (e.g. "sd0") with the letter identifying the partition (e.g. "d") appended (e.g. "sd0d"). Then it will ask where this partition is to be mounted, e.g. /usr. This process will be repeated until you just hit return. At this point you will be asked to confirm that the file system information you have entered is correct, and given an opportunity to change the file system table. Next it will create the new file systems as specified, OVERWRITING ANY EXISTING DATA. This is the point of no return. After all your file systems have been created, the install program will give you an opportunity to configure the network. The network configuration you enter (if any) can then be used to do the install from another system using NFS, HTTP or FTP, and will also be the configuration used by the system after the installation is complete. If you select to configure the network, the install program will ask you for a name of your system and the DNS domain name to use. Note that the host name should be without the domain part, and that the domain name should NOT {:-include-:} the host name part. Next the system will give you a list of network interfaces you can configure. For each network interface you select to configure, it will ask for the IP address to use, the symbolic host name to use, the netmask to use and any interface-specific flags to set. The interface-specific flags are usually used to determine which media the network card is to use. Supply the apropriate media options as suggested, Typically no media flags are required as autodetect normally works. After all network interfaces has been configured the install pro- gram will ask for a default route and IP address of the primary name server to use. You will also be presented with an opportunity to edit the host table. At this point you will be allowed to edit the file system table that will be used for the remainder of the installation and that will be used by the finished system, following which the new file systems will be mounted to complete the installation. After these preparatory steps has been completed, you will be able to extract the distribution sets onto your system. There are several install methods supported; FTP, HTTP, tape, CD-ROM, NFS or a local disk partition. To install from a tape, the distrib- ution sets must have been written to tape prior to running the installation program, either as tar images or as gzipped tar images. Note that installation from floppies are not currently supported.
