dnl $OpenBSD: install,v 1.41 2019/08/01 19:42:52 jmc Exp $ OpenBSDInstallPrelude There are several ways to install OpenBSD onto a disk. The easiest way is to boot from the bootable CD-ROM mini image, then install from your favorite source. You can also use one of the OpenBSD installation floppies, if your machine has a floppy drive. Network booting is supported through means of dhcpd(8) and tftpd(8). Booting from Floppy Disk installation media: At the SRM console prompt, enter boot dva0 You should see info about the primary and secondary boot and then the kernel should start to load. 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, or the machine spontaneously reboots, then either you have a bad boot floppy (in which case you should try another) or your alpha is not currently supported by OpenBSD. Booting from CD-ROM installation media: At the SRM console prompt, enter show device to find the device ID of your CD-ROM drive (the device ID is usually in the second column (``bootdev'') and should start with DKA for a SCSI CD-ROM drive). If your drive shows up with a drive number with trailing zeros, you will want to ignore them (unless it is DKA0). For example, if your CD-ROM drive is listed as DKA600, you want to use dka6 (device IDs are case insensitive). Insert the OpenBSD/MACHINE CD-ROM and enter boot DEVICE where DEVICE is the dka device name. You should see info about the primary and secondary boot and then the kernel should start to load. If the kernel fails to load or the spinning cursor has stopped and nothing further has happened, you either have a hardware problem or your MACHINE is not currently supported by OpenBSD; try booting from a floppy instead if possible. Booting from Network: In order to bootstrap via the network, you must provide a second system to act as a boot server. It is convenient if this is a second OpenBSD machine as the necessary services are already installed, although source code for such programs as dhcpd can be found in OpenBSD's source tree, and should be reasonably portable to other Unix-like operating systems. More information on diskless booting can be found in the OpenBSD diskless(8) manual page. Alpha systems can download their boot code over the network either using the old DEC MOP protocol, or the common bootp protocol. Older systems, such as the DEC 3000 systems, can only use the MOP protocol. Booting from a bootp or dhcp server: You will need to set up dhcpd on the server, which can serve bootp protocol requests. Start by editing the /etc/dhcpd.conf on the bootserver, and declare an information block. Here is an example: subnet 10.0.0.0 netmask 255.0.0.0 { host piper { always-reply-rfc1048 "true"; filename "netboot"; option root-path "/alpha"; hardware ethernet 08:00:2b:3d:28:2a; fixed-address 10.42.42.42; } } Do not forget to start dhcpd. You will also need to start tftpd, for the system to download the "netboot" file from the server in the /tftpboot directory. Booting from a MOP server: You will need to copy netboot.mop into /tftpboot/mop/1a2b3c4d5e6f.SYS, where "1a2b3c4d5e6f" represents the six octets of your Ethernet address, which can be obtained with ``show dev'' at the SRM prompt. For example, the filename for the machine in the dhcp example above would be "08002b3d282a.SYS". Note that the MAC portion of the filename must be lower case, but the "SYS" extension must be upper case. Do not forget to start mopd. Common netboot steps: A few more services need to be enabled on the boot server. First, add the Ethernet address to /etc/ethers file, as in: 08:00:2b:3d:28:2a piper and start rarpd. Second, you will need to export a directory for your new machine to mount over NFS, in order to get its kernel. This is accomplished by adding an entry to /etc/exports such as: /alpha piper The NFS server (which may be a different machine than the MOP or dhcp server) will need to run nfsd, mountd, and the rpc portmapper. See the exports(5) manpage for more information. Last, you will need to add an entry for your system in /etc/bootparams, to point to the NFS server. For example: piper root=myserver:/alpha and start bootparamd. Once loaded, the boot loader will mount /alpha over NFS and load the kernel from there. Installing using the Floppy, CD-ROM or Network procedure: OpenBSDInstallPart2 Boot your machine from the installation media as described above. It will take a while to load the installation kernel, especially from a slow network connection or a CD-ROM, 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 media is bad, your diskless setup is incorrect, or you may have a hardware or configuration problem.
