There is some info in
http://www.burdell.org/technotes/iri...nst_cds_65.txt
and
http://www.burdell.org/technotes/iri...g_inst_cds.txt
but dont forget, the files you have downloaded are just updates. You can
use them for upgrading any previous 6.5.x IRIX. If you're starting with a
blank disk, you need more than just the update files, i.e., you need IRIX
installation disks too. Older 6.5.x versions will do, but AFAIR x may
depend on how recent your SGI box is.

Thanks, I'll check those links out promptly!

I have the entire 6.5 base on CDs, as I'm no novice to IRIX 6.5. Anyway, I
learned by digging with Google that there's thins thingy called "mkefs" and
I even found a link pointing to it (at nekochan.net), but the link was
busted! ("mkefs" is not to be confused with mk_efs or mkfs -T efs.)

Does anyone know where one can get a copy of that "mkefs" tool?

Do you mean the script here: http://sigbus.nove.bg/pool/irix/CDR/?

Or https://toolbox.sgi.com/toolbox/utilities/CDmastering/?

Hm, good question, as they don't appear to be identical.

Using the SGI's mkefs script, you get two files, image.vh and image.efs.
That should solve the mastering problem. Using sgi's "burncd" tools is out
of the question, because they only support two types of specific writers;
which means I have to use cdrecord.

The question is, how does one pass the .vh and .efs files to cdrecord so
that the CD is burned bootable? Obviously, we're not dealing with an ISO
image here.

Question #2 is, what is the difference toolwise between sgi's and the
Bulgarian guy's?

cat image.vh image.efs |cdrecord -v -

For it to be really bootable, the right files have to be in the volume
header, i.e. the proper sash, a kernel, and for the sake of completeness
the ide*.

they are essentially the same.
