mkbootimage
utility creates bootable image files
from NetBSD/alpha bootstrap programs. Bootable image
files can be placed directly on disk or tape to create bootable media which
can be booted by the SRM console. This is primarily useful for creating
bootable tapes or disk sets with the
/usr/mdec/ustarboot bootstrap program, or for creating
firmware upgrade media using firmware upgrade programs.
The bootstrap program infile is padded to a 512-byte boundary, has a properly formed Alpha Boot Block prepended, and is written to the output file outfile. If no output file is specified, the result is written to standard output.
The mkbootimage
utility does not install
bootstrap programs to make disks bootable. To do that, use
installboot(8).
Similarly, it is not necessary to use mkbootimage
to
create images to boot over the network; network-capable bootstrap programs
are usable without modification.
The options recognized by mkbootimage
are
as follows:
mkbootimage
utility exits 0 on success,
and >0 if an error occurs.
mkbootimage as200_v5_8.exe as200_v5_8.exe.bootimage
Create a bootable image from the (firmware image) file as200_v5_8.exe. That bootable image could then be written to floppy, disk, CD-ROM, or tape to create bootable firmware update media.
(mkbootimage /usr/mdec/ustarboot; tar cvf - netbsd) | \ dd of=/dev/rst0
Make a bootable image from the bootstrap program /usr/mdec/ustarboot, concatenate it with a tar file containing a kernel, and write the output to a tape. This is an example of how to create a tape which boots a kernel.
mkbootimage
command first appeared in NetBSD 1.4.
