3 Tape, CD, Disk, and Netboot Images
4 ----- --- ----- --- ------- ------
6 This release or snapshot contains three installation image types.
7 The first, for floppies, is split into a multiple volume set.
9 installation/floppy/disk1of3
10 installation/floppy/disk2of3
11 installation/floppy/disk3of3
13 installation/diskimage/cdhdtape
15 installation/instkernel/netbsd.gz
17 All three boot images load the same installation kernel into memory
18 and then make no further use of the source media. The general idea
19 is to load a kernel with a pre-initialized memory filesystem of
20 utilities and an installation program.
22 The floppy image set uses two floppies to load the install kernel.
23 The cdhdtape image can be written to a CD, hard drive, or tape and
24 then booted from the SRM console. The kernel image can be netbooted
25 or loaded off the root directory of an existing installation.
27 Note: The netboot loader can load the netbsd.gz file directly; it
28 is not necessary to ungzip this kernel first.
30 To copy the boot images to a magnetic disk under unix, the dd(1)
34 dd if=disk1of3 of=/dev/rfd0a bs=18k
36 dd if=disk2of3 of=/dev/rfd0a bs=18k
38 dd if=disk3of3 of=/dev/rfd0a bs=18k
41 You can write the image to a hard drive too:
43 dd bs=18k if=cdhdtape of=/dev/rsd1c
44 dd bs=18k if=cdhdtape of=/dev/rsd1d (NetBSD/i386)
46 For a tape, it is important to use a block size of 512, so:
48 dd bs=512 if=cdhdtape of=/dev/erst0 (NetBSD)
49 dd bs=512 if=cdhdtape of=/dev/rmt0h (Digital Unix)
51 Note that the bits on the installation media are only used when
52 initially loaded. They can be written to a hard drive, loaded, and
53 then overwritten during the installation with no conflict, or
54 alternatively, the boot CD or tape can be removed and replaced with
55 one containing the installation sets.
57 The install notes from this directory subtree are present on the
58 installation file system.
