Default HPPA, creating boot cdrom ....


In reading the boot instructions for the HPPA, I see the section for
creating a boot tape, but I'd prefer to create a boot cdrom. Is this an
EL-Torito style boot cd with the LIF file stuck into the boot section on
the cd or does one simply attempt to BURN an iso image of a .tar file with
the LIF file as the first file in the archive?

I have an HP9000 712/60 (if it matters).

Cheers,
R

It's easy to create a boot CD from a running hppa/openbsd machine,
don't know about creating it on another architecture, though.
Create file.iso (I usually use mkhybrid) then do this:

dd if=/usr/mdec/cdboot of=${ISODIR}/file.iso bs=32k count=1 conv=notrunc
vnconfig -v -c svnd0 ${ISODIR}/file.iso
disklabel -w svnd0 fakecdrom "CD-ROM OpenBSD"
vnconfig -u svnd0
dd if=/dev/zero bs=64k count=1 >> ${ISODIR}/file.iso

I'm not 100% sure that the disklabel is needed, but at least it doesn't
seem to hurt.
