.\" $NetBSD: xfer,v 1.5 1999/02/20 16:18:11 scw Exp $ . Installation is supported from several media types, including: .Bl -bullet -compact .Pp .It Tape .It NFS .It CD-ROM .It FTP .El Note that installing on a "bare" machine requires either a bootable tape drive or an ethernet to a compatible NFS server. MVME147 may also need to be booted over an RS232 connection. .Pp The procedure for transferring the distribution sets onto installation media depends on the type of media. Instructions for each type of media are given below. .Pp In order to create installation media, you will need all the files and subdirectories in these two directories: .Pp .Dl Pa \&.../NetBSD-\*V/mvme68k/installation .Dl Pa \&.../NetBSD-\*V/mvme68k/binary . .Ss2 Creating boot/install tapes: . Installing from tape is the simplest method of all. This method uses two tapes, one containing a bootable ramdisk and miniroot, the other containing the installation sets. .Pp The boot tape is created as follows: .Pp .D1 Ic "cd .../NetBSD-\*V/mvme68k/installation .D1 Ic "set T = /dev/nrst0 .D1 Ic "mt -f $T rewind .D1 Ic "dd if=tapeimage/stboot of=$T .D1 Ic "dd if=tapeimage/bootst of=$T obs=8k conv=osync .D1 Ic "gzip -dc tapeimage/netbsd-rd.gz | dd of=$T obs=8k conv=osync .D1 Ic "gzip -dc miniroot/miniroot.gz | dd of=$T obs=8k conv=osync .D1 Ic "mt -f $T rewind .Pp The installation set tape is created as follows: .Pp .D1 Ic "cd .../NetBSD-\*V/mvme68k/binary/sets .D1 Ic "set T = /dev/nrst0 .D1 Ic "mt -f $T rewind .D1 Ic "foreach f (base etc comp games man misc text) .D1 Ic "gzip -d \*< $f.tgz | dd of=$T bs=8k .D1 Ic "end .D1 Ic "mt -f $T rewind .Pp If the tape does not work as expected, you may need to explicitly set the EOF mark at the end of each tape segment. Consult the tape-related manual pages on the system where the tapes are created for more details. . .Ss2 Boot/Install from NFS server: . If your machine has a disk and network connection, but no tape drive, it may be convenient for you to install .Nx over the network. This involves temporarily booting your machine over NFS, just long enough so you can initialize its disk. This method requires that you have access to an NFS server on your network so you can configure it to support diskless boot for your machine. Configuring the NFS server is normally a task for a system administrator, and is not trivial. .Pp If you are using a .Nx system as the boot-server, have a look at the .Xr diskless 8 manual page for guidelines on how to proceed with this. If the server runs another operating system, consult the documentation that came with it (i.e. add_client(8) on SunOS). .Pp Booting an MVME147 from ethernet is not possible without first downloading a small bootstrap program (sboot) via RS232. See the section entitiled "Installing from NFS" for details on how to accomplish this. .Pp sboot expects to be able to download a second stage bootstrap program via TFTP after having acquired its IP address through RARP It will look for a filename derived from the machine's IP address expressed in hexadecimal, with an extension of ".147". For example, an MVME147 with IP address 130.115.144.11 will make an TFTP request for `8273900B.147'. Normally, this file is just a symbolic link to the NetBSD/mvme68k "netboot" program, which should be located in a place where the TFTP daemon can find it (remember, many TFTP daemons run in a chroot'ed environment). The netboot program may be found in the install directory of this distribution. .Pp The MVME167 boot ROM has code builtin to boot over ethernet from a TFTP server. You should configure it to download the same "netboot" program as is used for MVME147. .Pp The netboot program will query a bootparamd server to find the NFS server address and path name for its root, and then load a kernel from that location. The server should have a copy of the netbsd-rd kernel in the root area for your client (no other files are needed in the client root, although it might be a convenient place to put the uncompressed miniroot image) and /etc/bootparams on the server should have an entry for your client and its root directory. Note that you should rename the netbsd-rd kernel to just 'netbsd' in the client's root directory before trying to netboot the client. .Pp The client will need access to the miniroot image, which can be provided using NFS or remote shell. If using NFS, miniroot.gz should be expanded on the server, because doing so from the RAMDISK shell is not so easy. The unzipped miniroot takes about 6Mb of space. .Pp If you will be installing .Nx on several clients, it may be useful to know that you can use a single NFS root for all the clients as long as they only use the netbsd-rd kernel. There will be no conflict between clients because the RAM-disk kernel will not use the NFS root. No swap file is needed; the RAM-disk kernel does not use that either. . .Ss2 Install/Upgrade from CD-ROM: . This method requires that you boot from another device (i.e. tape or network, as described above). You may need to make a boot tape on another machine using the files provided on the CD-ROM. Once you have booted netbsd-rd (the RAMDISK kernel) and loaded the miniroot, you can load any of the distribution sets directly from the CD-ROM. The "install" program in the miniroot automates the work required to mount the CD-ROM and extract the files. . .Ss2 Install/Upgrade via FTP: . This method requires that you boot from another device (i.e. tape or network, as described above). You may need to make a boot tape on another machine using the files in .../install (which you get via FTP). Once you have booted netbsd-rd (the RAM-disk kernel) and loaded the miniroot, you can load any of the distribution sets over the net using FTP. The "install" program in the miniroot automates the work required to configure the network interface and transfer the files. .Pp This method, of course, requires network access to an FTP server. This might be a local system, or it might even be ftp.NetBSD.ORG itself. If you wish to use ftp.NetBSD.ORG as your FTP file server, you may want to keep the following information handy: .Pp .Dl No IP Address: ftp.NetBSD.ORG .Dl Login: Ic anonymous .Dl Password: Ar your e-mail address .Dl Server path: Ic /pub/NetBSD/NetBSD-\*V/mvme68k/binary .(Note If you're not using a nameserver duing installation, you might find 204.152.184.75 handy; it's the IP address of ftp.NetBSD.ORG as of January, 1999. .Note)
