How 2 create an OpenBSD bootable DVD

gentisle · 05-23-2005, 10:20 PM

Hi,

Has anyone had sucess creating an OpenBSD bootable DVD that actually installs? I can create a bootable DVD, but when I get to the point of selecting the location where the install files are, it won't read the DVD. Are boot.catalog files different for CD and DVD? I can create a bootable CD that installs perfectly. Any help would be appreciated. Thanks.

With nero I create OpenBSD bootable DVD under windows os.

In nero I selected "create bootable DVD" and use "cdrom37.fs".

DVD contains directory 3.7 and all subdirectories and files that are needed for i386 platform.

Installation from bootable DVD works fine for me.

I have downloaded all the files in 3.7/i386. do i need to make an iso before i burn them? what would be the mkisofs command to make a bootable iso cd?

i do not have any problem burning them. so i just need to know the mkisofs command.

This is the way I prepare OpenBSD installation DVDs for myself.
I use Linux, but this should be usable in other OSes (like *BSD) as well.

For this example, I used the 3.7/i386 version, but please use your
version and/or architecture to suit your needs.

1) Make a directory, in which you will prepare the whole CD layout,
preferably in the temporary directory, an cd into it.

Code:

mkdir /tmp/OpenBSD
cd /tmp/OpenBSD

2) Get files in your favourite way and populate the OpenBSD directory
with files, preserving the layout of the mirror. Because there
are numerous ways of doing this, I will write how this is supposed
to look like:

Code:

/tmp/OpenBSD:
    3.7/
        i386/
	    CKSUM
	    INSTALL.i386
	    INSTALL.linux
	    MD5
	    ...
	packages/
		i386/
		    9libs-1.0p1.tgz
		    9menu-1.7.tgz
		    ...
		tools/
		     fips/
			 ...
		     fdimage.exe
		      ...
		ANNOUNCEMENT
		HARDWARE
		...

3) To be able to boot, you have to create a new directory "etc"
in the OpenBSD directory (not in 3.7!) and create a file
"boot.conf" with the following one-line content:

Code:

set image /3.7/i386/bsd.rd

After you are done, the layout will be:

Code:

/tmp/OpenBSD:
    3.7/
        ...
    etc/
        boot.conf

4) To be able to work with the DVD, we need to do some
permission changes. Do this in the command line
(you NEED NOT to be root).

Code:

you@yourdesk:/tmp/OpenBSD $ find -type f -exec chmod 0444 \{\} \;
you@yourdesk:/tmp/OpenBSD $ chmod 0555 3.7/i386/bsd
you@yourdesk:/tmp/OpenBSD $ chmod 0555 3.7/i386/bsd.mp
you@yourdesk:/tmp/OpenBSD $ chmod 0555 3.7/i386/bsd.rd
you@yourdesk:/tmp/OpenBSD $ chmod 0555 3.7/i386/cdboot
you@yourdesk:/tmp/OpenBSD $ chmod 0555 3.7/i386/cdbr
you@yourdesk:/tmp/OpenBSD $ chmod 0555 3.7/i386/pxeboot
you@yourdesk:/tmp/OpenBSD $ find -type d -exec chmod 0555 \{\} \;

5) Now, you are ready to make a burnable image. In the /tmp
directory, issue the following command:

Code:

# HERE ARE FOUR SPACES        ||||
#                             vvvv
mkisofs -R -T -V "OpenBSD/i386    3.7 install DVD" \
-p "Your Name <yname@your.domain>" \
-publisher "Your Name <yname@your.domain>" \
-A "OpenBSD 3.7 i386 unofficial install DVD" \
-b 3.7/i386/cdbr \
-c 3.7/i386/boot.catalog \
-no-emul-boot \
-uid 0 -gid 9 \
-o openbsd37.iso \
OpenBSD

Here you may need to change the -b and -c switch as I don't
know whether these apply to architectures other than i386.
Look into manual page for more information.

6) Now burn this image to DVD+R/DVD-R and enjoy.

For example, I use the following:

Code:

cdrecord-ProDVD -v dev=ATA:1,0,0 -dao /tmp/openbsd37.iso

7) Now you can delete the OpenBSD directory and the image.

I have used this way to make 3.6 i386 and 3.7 i386 bootable DVD.
