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.

As mentioned above, you will need your disk's geometry when creating OpenBSD partitions. You will also need to know the device name to tell the install tools what disk to install on.

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, the install program will then tell you which disks of that type it can install on, and ask you which it should use.

Reply with the name of your disk.-:})dnl dnl dnl OpenBSDInstallPart4(mention about other OS partitions) dnl Describes the disklabel operation dnl define({:-OpenBSDInstallPart4-:}, {:- 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'.$1 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". For help in the disk label editor, enter '?' or 'M' to view the manual page (see the info on the ``-E'' flag).-:})dnl dnl dnl OpenBSDInstallPart5 dnl More disklabel notes(disk) define({:-OpenBSDInstallPart5-:}, {:- 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. "$1") with the letter identifying the partition (e.g. "d") appended (e.g. "$1d"). 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.-:})dnl dnl dnl OpenBSDInstallNet(other installation sources,hasfloppy) dnl Setting up the network define({:-OpenBSDInstallNet-:}, {:- 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 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 the 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. Typically no media flags are required as autodetection normally works, but you will be prompted with a list of the acceptable media flags, and asked if you want to provide any. In doubt, do not enter any media flags; or you can refer to the manual page for your interface for the appropriate flags. 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.

You need to {:-define-:} a proxy if you are behind a firewall that blocks outgoing FTP (assuming you have a proxy available to use). 2) Do you need to use active mode FTP? By default, ftp will attempt to use passive mode and fall back to an active connection if the server does not support passive mode. You only need to enable this option if you are connecting to a buggy FTP daemon that implements passive FTP incorrectly. Note that you will not be asked about active FTP if you are using a proxy. 3) The IP address (or hostname if you enabled DNS earlier in the install) of an FTP server carrying the OpenBSD OSREV distribution. If you don't know, just hit return when asked if you want to see a list of such hosts. 4) The FTP directory holding the distribution sets. The default value of pub/OpenBSD/OSREV/MACHINE is almost always correct. 5) The login and password for the FTP account. You will only be asked for a password for non-anonymous FTP.

First you must identify the IP address of the NFS server to load the distribution from, and the file system the server expects you to mount. The install program will also ask whether or not TCP should be used for transport (the default is UDP). Note that TCP only works with newer NFS servers. You will also have to provide the relative path to the directory on the file system where the distribution sets are located. Note that this path should not be prefixed with a '/'.

The key issue is that the device name used for the floppy *must* be one that refers to the correct block device, not a partition or compatibility mode, and the copy command needs to be compatible with the requirement that writes to a raw device must be in multiples of 512-byte blocks. The variations are endless and beyond the scope of this document. If you're doing this on the system you intend to boot the floppy on, copying the floppy back to a file and doing a compare or checksum is a good way to verify that the floppy is readable and free of read/write errors. Note that, when installing, the boot floppy can be write-protected (i.e. read-only).-:})dnl dnl dnl Tape preparation instructions. dnl dnl OpenBSDXferBareTape describes how to set up a non-bootable distribution dnl tape, and takes as an optional argument, the list of X11 sets which dnl may be put on the tape. define({:-OpenBSDXferBareTape-:}, {:-Creating an installation tape: While you won't be able to boot OpenBSD from a tape, you can use one to provide the installation sets.

First you will need to transfer the distribution sets to your local system, using ftp or by mounting the CD-ROM containing the release. Then you need to make a tape containing the files.

If you aren't, this documentation should help, but is not intended to be all-encompassing. Place the OpenBSD distribution sets you wish to install into a directory on an NFS server, and make that directory mountable by the machine on which you are installing or upgrading OpenBSD. This will probably require modifying the /etc/exports file of the NFS server and resetting its mount daemon (mountd). (Both of these actions will probably require superuser privileges on the server.) You need to know the numeric IP address of the NFS server, and, if the server is not on a network directly connected to the machine on which you're installing or upgrading OpenBSD, you need to know the numeric IP address of the router closest to the OpenBSD machine.

These errors are inconsequential for the purpose of installing OpenBSD. However, you may want to correct them if you plan to use the diskless setup regularly.
