Installation is supported from several media types, including:
|
|
|
|
FTP
|
|
Remote NFS partition
|
|
DOS floppies
|
|
|
|
No matter which installation medium you choose, you'll need to have a
|
|
floppy disk (either 1.2M or 1.44M will work). You'll put the boot
|
|
floppy image ("boot.fs" for 1.44M floppies, "boot-small.fs" for 1.2M
|
|
floppies) onto this disk, which contains software to install or
|
|
upgrade your NetBSD system.
|
|
|
|
[Note: previous versions of NetBSD used several floppy images,
|
|
including several kernel/boot floppies depending on hardware
|
|
configuration, an install floppy, and an upgrade floppy. NetBSD _VER
|
|
only requires a single floppy for all tasks.]
|
|
|
|
If you are using a UN*X-like system to write the floppy images to
|
|
disks, you should use the "dd" command to copy the file system image
|
|
(.fs file) directly to the raw floppy disk. It is suggested that you
|
|
read the dd(1) manual page or ask your system administrator to
|
|
determine the correct set of arguments to use; it will be slightly
|
|
different from system to system, and a comprehensive list of the
|
|
possibilities is beyond the scope of this document.
|
|
|
|
If you are using DOS to write the floppy image to disk, you should
|
|
use the "rawrite" utility, provided in the "i386/utilities" directory
|
|
of the NetBSD distribution. It will write the file system image (.fs
|
|
file) to disks.
|
|
|
|
Note that, when installing or upgrading, the floppy can be
|
|
write-protected if you wish. These systems mount ramdisks as their
|
|
root file systems once booted, and will not need to write to the
|
|
floppy itself at any time -- indeed, once booted, the floppy may be
|
|
removed from the disk drive.
|
|
|
|
Obviously, the steps necessary to prepare the distribution sets for
|
|
installation or upgrade depend on which installation medium you
|
|
choose. The steps for the various media are outlined below.
|
|
|
|
To install or upgrade NetBSD using DOS floppies, you need to do the
|
|
following:
|
|
|
|
Count the number of "set_name.xx" files that make up the
|
|
distribution sets you want to install or upgrade. You will
|
|
need one fifth that number of 1.2M floppies, or one sixth that
|
|
number of 1.44M floppies. You should only use one size of
|
|
floppy for the install or upgrade procedure; you can't use
|
|
some 1.2M floppies and some 1.44M floppies.
|
|
|
|
Format all of the floppies with DOS. DO NOT make any of them
|
|
bootable DOS floppies, i.e. don't use "format/s" to format
|
|
them. (If the floppies are bootable, then the DOS system
|
|
files that make them bootable will take up some space, and you
|
|
won't be able to fit as many distribution set parts per disk.)
|
|
If you're using floppies that are formatted for DOS by their
|
|
manufacturers, they probably aren't bootable, and you can use
|
|
them out of the box.
|
|
|
|
Place all of the "set_name.xx" files on the DOS disks, five
|
|
per disk if you're using 1.2M disks, six per disk if you're
|
|
using 1.44M disks. How you do this is up to you; there are
|
|
many possibilities. You could, for instance, use a DOS
|
|
terminal program to download them on to the floppies, or use
|
|
a UN*X-like system capable of reading and writing DOS file
|
|
systems (either with "mtools" or a real DOS file system)
|
|
to place them on the disk.
|
|
|
|
Once you have the files on DOS disks, you can start the
|
|
actual installation or upgrade process.
|
|
|
|
To install or upgrade NetBSD using NFS, you must do the following:
|
|
|
|
Place the NetBSD 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 NetBSD.
|
|
This will probably require modifying the /etc/exports file on
|
|
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 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 NetBSD,
|
|
you need to know the numeric IP address of the router closest
|
|
to the NetBSD machine. Finally, you need to know the numeric
|
|
IP address of the NetBSD machine itself. The install
|
|
program will ask you to provide this information to be able
|
|
to access the sets.
|
|
|
|
Once the NFS server is set up properly and you have the
|
|
information mentioned above, you can start the actual
|
|
installation or upgrade process.
|
|
|
|
To install or upgrade NetBSD by using FTP to get the installation
|
|
sets, you must do the following:
|
|
|
|
The preparations for this installation/upgrade method are
|
|
easy; all you make sure that there's some FTP site from which
|
|
you can retrieve the NetBSD distribution when you're about to
|
|
install or upgrade. You need to know the numeric IP address
|
|
of that site, and, if it's not on a network directly connected
|
|
to the machine on which you're installing or upgrading NetBSD,
|
|
you need to know the numeric IP address of the router closest
|
|
to the NetBSD machine. Finally, you need to know the numeric
|
|
IP address of the NetBSD machine itself. The install program
|
|
will ask you to provide this information to be able to access
|
|
the sets via ftp.
|
|
|
|
Once you have this information, you can proceed to the actual
|
|
installation or upgrade.
|
|
|
|
If you are upgrading NetBSD, you also have the option of installing
|
|
NetBSD by putting the new distribution sets somewhere in your existing
|
|
file system, and using them from there. To do that, you must do the
|
|
following:
|
|
|
|
Place the distribution sets you wish to upgrade somewhere in
|
|
your current file system tree. Please note that the /dev on
|
|
the floppy used for upgrades only knows about wd0, wd1, sd0,
|
|
sd1 and sd2. If you have more than two IDE drives or more than
|
|
three SCSI drives, you should take care not to place the sets
|
|
on the high numbered drives.
|
|
|
|
At a bare minimum, you must upgrade the "base" and "kern"
|
|
binary distribution, and so must put the "base" and
|
|
"kern" sets somewhere in your file system. If you wish,
|
|
you can do the other sets, as well, but you should NOT upgrade
|
|
the "etc" distribution; the "etc" distribution contains system
|
|
configuration files that you should review and update by hand.
|
|
|
|
Once you have done this, you can proceed to the next step in
|
|
the upgrade process, actually upgrading your system.
