1 2 Tape, CD, and Disk Images 3 4This release or snapshot contains two installation image types: 5 6 installation/floppy/disk1of2 7 installation/floppy/disk2of2 8 9and 10 installation/diskimage/cdhdtape 11 12Both image sets load the same installation kernel into memory and 13then make no further use of the source media. The general idea is 14to load a kernel with a pre-initialized memory filesystem of 15utilities and an installation program. 16 17The use of the floppy disk set should be obvious. The cdhdtape 18image can be written to a CD, hard drive, or tape and then booted 19from the SRM console. 20 21To copy the boot images to a magnetic disk under unix, the dd(1) 22command can be used: 23 24Floppy: 25 dd if=disk1of2 of=/dev/rfd0a bs=18k 26 (change floppies) 27 dd if=disk2of2 of=/dev/rfd0a bs=18k 28 29You can write the image to a hard drive too: 30 31 dd bs=18k if=cdhdtape of=/dev/rsd1c 32 dd bs=18k if=cdhdtape of=/dev/rsd1d (NetBSD/i386) 33 34For a tape, it is important to use a block size of 512, so: 35 36 dd bs=512 if=cdhdtape of=/dev/erst0 (NetBSD) 37 dd bs=512 if=cdhdtape of=/dev/rmt0h (Digital Unix) 38 39Note that the bits on the installation media are only used when 40initially loaded. They can be written to a hard drive, loaded, and 41then overwritten during the installation with no conflict, or 42alternatively, the boot CD or tape can be removed and replaced with 43one containing the installation sets. 44 45The install notes from this directory subtree are present on the 46installation file system. 47
