Tape, CD, and Disk Images
|
|
|
|
This release or snapshot contains two installation image types:
|
|
|
|
installation/floppy/disk1of2
|
|
installation/floppy/disk2of2
|
|
|
|
and
|
|
installation/diskimage/cdhdtape
|
|
|
|
Both image sets 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 use of the floppy disk set should be obvious. The cdhdtape
|
|
image can be written to a CD, hard drive, or tape and then booted
|
|
from the SRM console.
|
|
|
|
To copy the boot images to a magnetic disk under unix, the dd(1)
|
|
command can be used:
|
|
|
|
Floppy:
|
|
dd if=disk1of2 of=/dev/rfd0a bs=18k
|
|
(change floppies)
|
|
dd if=disk2of2 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.
