Tape, CD, Disk, and Netboot Images
|
|
----- --- ----- --- ------- ------
|
|
|
|
This release or snapshot contains three installation image types.
|
|
The first, for floppies, is split into a multiple volume set.
|
|
|
|
installation/floppy/disk1of3
|
|
installation/floppy/disk2of3
|
|
installation/floppy/disk3of3
|
|
|
|
installation/diskimage/cdhdtape
|
|
|
|
installation/instkernel/netbsd.gz
|
|
|
|
All three boot images load the same installation kernel into memory
|
|
and then make no further use of the source media. The general idea
|
|
is to load a kernel with a pre-initialized memory filesystem of
|
|
utilities and an installation program.
|
|
|
|
The floppy image set uses two floppies to load the install kernel.
|
|
The cdhdtape image can be written to a CD, hard drive, or tape and
|
|
then booted from the SRM console. The kernel image can be netbooted
|
|
or loaded off the root directory of an existing installation.
|
|
|
|
Note: The netboot loader can load the netbsd.gz file directly; it
|
|
is not necessary to ungzip this kernel first.
|
|
|
|
To copy the boot images to a magnetic disk under unix, the dd(1)
|
|
command can be used:
|
|
|
|
Floppy:
|
|
dd if=disk1of3 of=/dev/rfd0a bs=18k
|
|
(change floppies)
|
|
dd if=disk2of3 of=/dev/rfd0a bs=18k
|
|
(change floppies)
|
|
dd if=disk3of3 of=/dev/rfd0a bs=18k
|
|
|
|
|
|
You can write the image to a hard drive too:
|
|
|
|
dd bs=18k if=cdhdtape of=/dev/rsd1c
|
|
dd bs=18k if=cdhdtape of=/dev/rsd1d (NetBSD/i386)
|
|
|
|
For a tape, it is important to use a block size of 512, so:
|
|
|
|
dd bs=512 if=cdhdtape of=/dev/erst0 (NetBSD)
|
|
dd bs=512 if=cdhdtape of=/dev/rmt0h (Digital Unix)
|
|
|
|
Note that the bits on the installation media are only used when
|
|
initially loaded. They can be written to a hard drive, loaded, and
|
|
then overwritten during the installation with no conflict, or
|
|
alternatively, the boot CD or tape can be removed and replaced with
|
|
one containing the installation sets.
|
|
|
|
The install notes from this directory subtree are present on the
|
|
installation file system.
