OpenBSDInstallPrelude If OpenBSD will be sharing the disk with DOS or another operating system, you should have already completed the section of these notes that instructed you on how to prepare your hard disk. You should know the size of the OpenBSD area of the disk and its offset from the beginning of the disk. You will need this information when setting up your OpenBSD partitions. If your BIOS uses translated geometry, you should use this geometry for the remainder of the install. This is only necessary if you are sharing the disk with other operating systems that use the translated geometry. OpenBSDInstallPart2 Boot your machine using the floppy{:--:}OSrev.fs floppy. When presented with the boot prompt hit return. If the boot prompt does not appear in a reasonable amount of time, you either have a bad boot floppy or a hardware problem. Try writing the floppy{:--:}OSrev.fs floppy image to a different disk, and using that. If that doesn't work, try booting after disabling your CPU's internal and external caches (if any). If it still doesn't work, OpenBSD probably can't be run on your hardware. This can probably be considered a bug, so you might want to report it. If you do, please {:-include-:} as many details about your system configuration as you can. It will take a while to load the kernel from the floppy, most likely more than a minute. If some action doesn't eventually happen, or the spinning cursor has stopped and nothing further has happened, either your boot floppy is bad or you are having hardware problems, and should proceed as outlined above. OpenBSDBootMsgs 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. Now you will be asked whether you wish to do an "install" or an "upgrade". Enter 'i' for a fresh install or 'u' to upgrade an existing installation. You will be presented with a welcome message and asked if you really wish to install (or upgrade). Assuming you answered yes, you will be asked which terminal type to use. You should just hit return to select the default (pcvt25). 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/RLL/ESDI/ST506 drives or "sd0" for SCSI drives. Reply with the name of your disk. Next you will have to edit or create a disk label 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 interactive 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. If you are labeling a new disk, you will probably start out with an 'a' partition that spans the disk. In this case You should delete 'a' before adding new partitions. 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, /tmp, and /var, and if you have room for it, one for /home. In doing this, remember to skip 'c', leaving it as type "unused". Create your next partition as 'd' and continue from there with any additional partitions. If you have DOS or Linux partitions defined on the disk, these will usually show up as partition 'h', 'i', and so on. When you are finished with disklabel you will be prompted for the mount points for the partitions in the current label. For help in the disk label editor, enter '?' or 'M' to view the manual page (see the info on the ``-E'' flag). 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 if the disk is not being shared with other operating systems, and within the OpenBSD fdisk partition if the disk is being shared. 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. "wd0") with the letter identifying the partition (e.g. "d") appended (e.g. "wd0d"). Then it will ask where this partition is to be mounted, e.g. /usr. This process will be repeated until you enter "done". 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. The flags usually carry the following meaning: -link0 -link1 Use BNC (coaxial) port [default] link0 -link1 Use AUI port link0 link1 Use UTP (twisted pair) port After all network interfaces have 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 have 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 is not currently supported.
