      3 Installation is supported from several media types, including:
      4 
      5         FTP
      6         Remote NFS partition
      7         CD-ROM
      8 
      9 No matter which installation medium you choose, you'll need to have
     10 either a 1.44 MB floppy disk (if your Alpha has a floppy drive to
     11 boot from) or you'll have to set up a server with BOOTP, TFTP and
     12 NFS to boot from as described later in this document.
     13 
     14 If you are using a UN*X-like system to write the floppy images to
     15 disks, you should use the "dd" command to copy the file system image
     16 (.fs file) directly to the raw floppy disk.  It is suggested that you
     17 read the dd(1) manual page or ask your system administrator to
     18 determine the correct set of arguments to use; it will be slightly
     19 different from system to system, and a comprehensive list of the
     20 possibilities is beyond the scope of this document.
     21 
     22 If you are using DOS to write the floppy image to disk, you should
     23 use the "rawrite" utility, provided in the "i386/utilities" directory
     24 of the NetBSD distribution.  It will write the file system image (.fs
     25 file) to disks.
     26 
     27 Note that, when installing or upgrading, the floppy can be
     28 write-protected if you wish. These systems mount ramdisks as their
     29 root file systems once booted, and will not need to write to the
     30 floppy itself at any time -- indeed, once booted, the floppy may be
     31 removed from the disk drive.
     32 
     33 Obviously, the steps necessary to prepare the distribution sets
     34 for installation depend on which installation medium you choose.
     35 The steps for the various media are outlined below.
     36 
     37 To install NetBSD using NFS to get the installation sets, you must
     38 do the following:
     39 
     40         Place the NetBSD distribution sets you wish to install into a
     41         directory on an NFS server, and make that directory mountable
     42         by the machine on which you are installing or upgrading NetBSD.
     43         This will probably require modifying the /etc/exports file on
     44         of the NFS server and resetting its mount daemon (mountd).
     45         (Both of these actions will probably require superuser
     46         privileges on the server.)
     47 
     48         You need to know the the numeric IP address of the NFS server,
     49         and, if the server is not on a network directly connected to
     50         the machine on which you're installing or upgrading NetBSD,
     51         you need to know the numeric IP address of the router closest
     52         to the NetBSD machine.  Finally, you need to know the numeric
     53         IP address of the NetBSD machine itself. The install
     54         program will ask you to provide this information to be able
     55         to access the sets.
     56 
     57         Once the NFS server is set up properly and you have the
     58         information mentioned above, you can start the actual
     59         installation process.
     60 
     61 To install NetBSD by using FTP to get the installation sets, you
     62 must do the following:
     63 
     64         The preparations for this installation method are easy;
     65         all you make sure that there's some FTP site from which
     66         you can retrieve the NetBSD distribution when you're about
     67         to install. You need to know the numeric IP address of that
     68         site, and, if it's not on a network directly connected to
     69         the machine on which you're installing or upgrading NetBSD,
     70         you need to know the numeric IP address of the router
     71         closest to the NetBSD machine.  Finally, you need to know
     72         the numeric IP address of the NetBSD machine itself. The
     73         install program will ask you to provide this information
     74         to be able to access the sets via ftp.
     75 
     76         Once you have this information, you can proceed to the actual
     77         installation.
     78 
     79 To install NetBSD by using a CD-ROM to get the installation sets,
     80 you must do the following:
     81 
     82         Have a CD-ROM with the installation sets on it, and a CD-ROM
     83         drive on your machine.
     84 
     85 If you are upgrading NetBSD, you also have the option of installing
     86 NetBSD by putting the new distribution sets somewhere in your existing
     87 file system, and using them from there.  To do that, you must do the
     88 following:
     89 
     90         Place the distribution sets you wish to upgrade somewhere in
     91         your current file system tree. Please note that the /dev on
     92         the floppy used for upgrades only knows about wd0, wd1, sd0,
     93         sd1 and sd2. If you have more than two IDE drives or more than
     94         three SCSI drives, you should take care not to place the sets
     95         on the high numbered drives.
     96 
     97         At a bare minimum, you must upgrade the "base" and "kern"
     98         binary distribution, and so must put the "base" and
     99         "kern" sets somewhere in your file system.  If you wish,
    100         you can do the other sets, as well, but you should NOT upgrade
    101         the "etc" distribution; the "etc" distribution contains system
    102         configuration files that you should review and update by hand.
    103 
    104         Once you have done this, you can proceed to the next step in
    105         the upgrade process, actually upgrading your system.
