I just thought of something that will make the install a lot easier if
you've got an existing UNIX box, a CD-burner, and a CD-ROM that does
512-byte blocks. I used this to make a bootable CD-ROM for my SparcBook 3GS
(I toasted the Solaris 2.5.1 that was on it by installing Sun's Y2K

I used the following proceedure on my Sparc 20/712 running Solaris 2.6 and
then copied the resulting image over to my Mac and burned it to CD-R.
Worked great once I figured out how to boot it. Beware, the OpenBSD utility
for setting up your disk is a royal pain.

If you don't have the hardware/software to do this, you can also make a boot
floppy or dd miniroot28.fs (I think that's the right one) to a second HD.

OpenBSD Bootable Sparc CD-ROM How-To

Many thanks are owed to the authors of mksunbootcd and the NetBSD Bootable

Step 1.

Create an ISO out of the files you wish to include on the CD. The first
disc I made was 79MB and included just the base packages, ports.tar.gz and
some readme files. There is plenty of room to add 150MB of sparc packages,
source tar balls, etc.

mkisofs -o ~/obsd28sparc.iso -T -a -l -J -r -L \
 -V "OpenBSD2.8_sparc" /mnt/cdrom/2.8/sparc

Check the man page for mkisofs to see what all the switches do. For me it
was important to select a couple of options so the disc would show up
properly under Win2k; translation tables (-T) for lower case file names
and a volume ID (-V).

In case you're using an OS that doesn't already have mkisofs, it can be
retrieved here:

Step 2.

Retrieve a bootable floppy image of OpenBSD. At the time of this writing I

Step 3.

Compile and install mksunbootcd. This tool will allow you to append a sun
disklabel and OpenBSD boot image to the ISO.

You can find mksunbootcd here:

Step 4.

Create the final ISO. I used the following command:
mksunbootcd obsd28sparc.iso floppy28.fs floppy28.fs floppy28.fs

If you happen to have different boot images for sun4, sun4c, and sun4m
architectures, you might use a command like this:
mksunbootcd obsd28sparc.iso obsd-sun4.fs obsd-sun4c.fs obsd-sun4m.fs

Be sure not to run this command more than once since it rewrites the ISO
file. Once you have burned the ISO to a CD you should be able to run 'boot
cdrom'. See the current INSTALL.sparc file for equivalent commands with
different OpenBoot versions.

Step 5.

Contribute to the OpenBSD project. Every six months I try to buy at least
one copy of the official CD-ROM and usually go crazy with t-shirt
purchases. See for more info.
